We’re happy to report that our search for the PERFECT scratch Lemon Blueberry Cake is over!
The flavor combination of tangy lemon balanced with sweet blueberries has always been a popular choice for desserts, especially in the spring and summer months.
We’ve wanted to add a lemon blueberry layer cake to our site for a while now, and are so happy to have a recipe that we think you are going to absolutely LOVE!
How to Make lemon Blueberry Cake
This moist Lemon Blueberry Cake is sure to become a favorite!
You can find the full, printable lemon blueberry cake further down in this post, but here is a quick rundown of our steps!
- Preheat the oven to 350 degrees F. Grease and flour three 8 inch round pans. I also like to line them with circles of parchment paper.
- In a medium sized bowl add the flour, baking powder, baking soda and salt. Whisk to blend, set aside.
- In another bowl or measuring cup combine the sour cream, lemon juice and lemon zest, vanilla extract and lemon extract and set aside.
- In the bowl of your mixer, beat the softened butter until smooth. Next, slowly add the sugar and mix on medium speed for 3 to 5 minutes until fluffy.
- Add the room temperature eggs one at a time, mixing until the yellow of the yolk disappears.
- Add the flour mixture and the sour cream mixture alternately, beginning and ending with flour mixture (three additions of dry ingredients and two of wet). Mix until combined, do not mix above medium speed or overmix.
- Toss the blueberries in 1 Tablespoon flour and gently fold into the cake batter. The cake batter is very thick. Divide the batter between the 3 pans smoothing the tops with the back of a spoon.
- Bake at 350 degrees for 25 to 28 minutes or until a toothpick inserted into the center comes out clean or with just a few crumbs attached. Let the cakes cool on a wire rack for 5-10 minutes before turning out.
How to Keep the Blueberries from Sinking while baking
For this cake recipe, we knew that we wanted the blueberries to be baked into the lemon cake layers, and more importantly, that we wanted the blueberries to stay suspended and evenly distributed. Little did we know what a challenge this would be!
We experimented with SO MANY lemon blueberry cake recipes before finding “the one”. We played around with our favorite lemon cake recipe from our site, but the batter wasn’t thick enough to keep the berries evenly distributed.
Whether we tossed the blueberries in flour, used tiny wild blueberries, sliced the blueberries into tiny pieces, or sprinkled them on top of the batter before popping into the oven, it made no difference. The blueberries always fell to the bottom. Agggh!
We were beginning to think that cake layers with perfectly suspended blueberries were just a myth and all of the blueberry cake photos that we saw online were photoshopped, haha.
Finally, we tried a twist on our favorite White Almond Sour Cream Cake because the batter is nice and thick. The result was perfectly suspended berries– Woohoo! Such a proud moment! We could hardly believe it ourselves.
This cake tastes amazing, and the sour cream in the recipe lends a lovely texture and moistness.
You’ll notice in our recipe that we call for frozen wild blueberries (because of their small size) and we still toss them in a bit of flour.
This is all done as a precaution to make sinking blueberries less likely, however the thickness of the batter should keep your blueberries suspended no matter what their size.
Assembly of the lemon blueberry cake
We decided to boost the lemon and blueberry flavors in this lemon blueberry cake recipe with our luscious lemon cream cheese frosting in between the cake layers as well as a delicious blueberry buttercream!
You may have noticed that we have a thing for cream cheese frosting- we absolutely love it and many of our cake recipes call for a cream cheese frosting or filling– feel free to change things up as you like! A lemon curd or lemon buttercream would taste great too!
Since our lemon cream cheese filling is a little soft, I piped a blueberry buttercream dam about ¼ inch inside of the edge of the cake before filling. This helps to keep the filling right where it belongs as the layers are assembled.
We love this Blueberry Buttercream Frosting Recipe!
I love the speckled look of the blueberry buttercream, and the blueberry flavor really comes through! In this frosting recipe, you’ll see that the blueberry buttercream’s key ingredient is a flavorful blueberry syrup, which is a simple reduction.
We made enough blueberry buttercream for generously frosting and decorating this three layer cake- it pipes perfectly! After giving the cake some time to settle, I crumb coated our lemon blueberry cake and used a star tip 21 to make patterns of overlapping rosettes and vertical lines. I could pipe buttercream designs all day!
We served this cake for a family get together that we recently had for the Fourth of July and everyone loved it! If you’re a fan of lemon or blueberry, or both- you must put this recipe on your “must make” list! It’s a keeper!

Lemon Blueberry Cake
This homemade Lemon Blueberry Cake is the perfect balance of lemon and blueberry flavor! So moist and perfect for spring and summer gatherings!
Ingredients
For the Cake
- 2 sticks (226g) unsalted butter, slightly softened
- 2 cups (400g) sugar
- 3 large room temperature eggs
- 1 cup (242g) sour cream
- ⅓ cup — juice and zest of 2 lemons
- 1 teaspoon (4g) vanilla extract
- 1 Tablespoon (10g) lemon extract
- 3 cups (342g) cake flour (plain in the UK) — if you do not have cake flour see substitution below
- 1 ½ teaspoons (7g) baking powder
- ½ teaspoon (3g) baking soda
- ½ teaspoon (3g) salt
- 1 ½ cups wild blueberries (tossed in 1 Tablespoon flour) — Keep the berries frozen until just before stirring in. Wild blueberries are smaller and are less likely to sink in the cake batter. You can use fresh or frozen I usually use frozen. This cake batter is very thick, this also helps to keep the blueberries from sinking.
For the Blueberry Syrup
- 1 cup blueberries (125g)
- 2 Tablespoons sugar (27g)
- ¼ cup water (57g)
For the Blueberry Buttercream Frosting
- 3 sticks (354g) unsalted butter
- 7 ½ cups (863g) powdered sugar
- 2 teaspoons (8g) vanilla
- ½ to 1 teaspoon salt (optional to cut sweetness)
- ¼ cup plus 2 tablespoons blueberry syrup- more if needed to reach your desired consistency
For the Lemon Cream Cheese Filling
- 1 sticks (113g) unsalted butter, slightly softened but still cool to the touch
- 1 8oz package Cream Cheese (226 total gram weight) Use full fat cream cheese. Do not use reduced fat or cream cheese in the tub containers. Soften very slightly
- 1 teaspoon (4g) lemon juice
- ½ teaspoon (2g) lemon extract, optional
- Zest of One Lemon approximately 1.5 teaspoons (3g)
- 3 to 3 ½ cups (345g - 374g) powdered sugar, adding more if necessary
Instructions
INSTRUCTIONS FOR THE CAKE
- Preheat the oven to 350 degrees F, grease and flour three 8x2 inch round cake pans. Three layers will give you slightly shorter layers but more filling per slice.
- In a medium sized bowl add the flour, baking powder, baking soda and salt. Whisk to blend, set aside.
- In another bowl or measuring cup add the sour cream, lemon juice and zest, vanilla and lemon extract. Blend with a fork and set aside
- In the bowl of your mixer, beat the softened butter until smooth. Gradually ad the sugar and beat on medium speed for 3 to 5 minutes until it is lightened in color and fluffy.
- Add the eggs one at a time, mixing until the yellow of the yolk disappears.
- Add the flour mixture and the sour cream mixture alternately, beginning and ending with flour mixture (3 additions of dry ingredients and 2 of wet). Mix until combined and smooth, do not mix above medium speed or over mix.
- Toss the blueberries in 1 Tablespoon flour and gently fold into the cake batter. The cake batter is very thick. Divide the batter between the 3 pans smoothing the tops with the back of a spoon.
- Bake at 350 degrees for 25 to 28 minutes or until a toothpick inserted into the center comes out clean or with just a few crumbs attached. Let the cakes cool 5 to 10 minutes then turn out.
- Makes 7 cups cake batter
- (This recipe works well for cupcakes too)
INSTRUCTIONS FOR THE BLUEBERRY SYRUP (FOR USE IN BUTTERCREAM)
- To a saucepan add the above ingredients and cook over low heat until sugar dissolves. Increase to medium heat and cook until the mixture is reduced a bit. Cool the syrup before using in the buttercream. It can be refrigerated 3 to 5 days in the refrigerator.
INSTRUCTIONS FOR BLUEBERRY BUTTERCREAM
- Cream the softened butter until smooth. Blend in the vanilla.
- Gradually add the powdered sugar and blueberry syrup until the powdered sugar is incorporated . Mix on medium speed 4 to 6 minutes or until smooth. Slowing the mixer down to a low speed setting during the last minute of mixing helps to eliminate air pockets.
- Makes 6 cups frosting
INSTRUCTIONS FOR THE LEMON CREAM CHEESE FROSTING
- Cut butter into ½ inch slices and add to the bowl of your mixer, beat until smooth.
- Cut the cream cheese into pieces and add to the butter, beating until blended.
- Add the lemon juice and lemon zest. ½ teaspoon lemon extract, (optional) for a stronger lemon flavor.
- Gradually add powdered sugar and beat until well blended.
- This frosting will pipe best if used while still chilled. You can make it in advance, refrigerate and when ready to use let it soften slightly and remix. Do not microwave to soften.
ASSEMBLY
- Place the first layer on your pedestal or cake base. Pipe a dam of blueberry buttercream about ¼ inch within the edge of your cake layer and fill with lemon cream cheese frosting.
- Add next layer and repeat.
- Frost the cake with blueberry buttercream. I like to apply a thin crumb coat layer first, and then follow either with a second layer of frosting, or with piping as I did in today's cake. I used a star tip 21 to create the piped designs. Due to the cream cheese frosting, this cake should be refrigerated until within a few hours of serving.
SUBSTITUTION FOR CAKE FLOUR
- For each cup of flour in the recipe, remove 2 Tablespoons of flour and replace with 2 Tablespoons cornstarch. This recipe has 3 cups of flour, measure out 3 cups of all purpose flour, remove 6 Tablespoons and replace with 6 Tablespoons cornstarch, whisk to blend.

Cake flour? What would we use in the UK?
Hi Alison, I’m sorry I forgot to add the substitution. I just added it to the end of the recipe. In the UK you can use plain flour in the substitution. For each cup of flour in the recipe, remove 2 Tablespoons flour and replace with 2 Tablespoons cornstarch (it may be know as corn flour in the UK, not sure). This recipe has 3 cups of flour, measure out the all purpose or plain flour, remove 6 Tablespoons and replace with 6 Tablespoons cornstarch, whisk to blend.
Looks amazing! I’m going to get some blueberries as soon as possible to try this. I believe I will use a few drops of lemon oil in place of the extract (I am not very fond of lemon extract). Other than that, it looks perfect!
Review 1 of 2.
I have weddings, baptisms, anniversaries and such going on, that I am making cakes all the time lately. Therefore, little sleep. I just finished making this cake at 6:19 AM
Yesterday, I was asked to make a lemon blueberry cake. So, I had planned on using the America’s Test Kitchen lemon cake, with a blue berry jam. I have used it in the past and liked it. So that means, I normally use a vanilla cake with a strong lemon simple syrup.
However, I recently made the chocolate cake from this site and it was absolutely fantastic. So, I decided to give this cake a try for 2 reasons. 1: the cake has 3 different kinds of lemon in it (it is really hard to make a lemon cake taste like lemon), 2: The frosting used a blue berry reduction that I have never thought of…it simply intrigued me.
On to the actual review: I was unable to obtain frozen wild blue berries. So, I took fresh berries, washed and got all of the stems off and froze them overnight in a flat strainer. I picked out the smaller ones and used them.
When making the cake, I have to admit, I didn’t like the addition of the lemon extract. It smells bad to me. So, I thought it had ruined the cake, but I wanted to try to it exactly as written since it includes zest and juice.
Once the batter was prepared, I was surprised that it wasn’t as thick as I expected. BUT once I added the frozen blue berries, it thickened up significantly. Be sure to have a small offset spatula available or a bent spoon so you can smooth it out. There is no way you will be able to tap it down to make it flat. It reminded me of cookie dough.
I was able to make 2 8 inch and a small tester for my daughter (4 inch). This kid loves everything blue berry (pancakes, muffins, cereal bars, yogurt). I needed her to be a tester because this will be for a client and I will not have any to sample. I was in the process of making another cake when she stumbled into the kitchen.
I told her I had made her a cake, she pulled it out and took a bite. I asked it if tasted like pancakes or muffins, she replied..”OMG, this is the best cake I have ever eaten., out of 10 it’s an 11,000.” I quickly asked for a bite and there was none.
I would add one note if anyone made this. Do not be concerned about the thickness of the batter. Instinctively, I assumed it would take a long time like a pound cake, but it didn’t. It’s the addition of the frozen berries that makes the batter so thick.
I have asked the recipient of the actual cake to take a picture and get reviews from 5 guests of different ages and I will add that to my 2/2 review in about a week or so.
Hi there, I can’t find wild blueberries. Will regular frozen blueberries work? Thank you!
Hi Megan, Yes, you can use regular frozen blueberries. As I mentioned in the comments wild blueberries are smaller and less likely to sink. The cake batter is thick so hopefully that will keep your berries suspended. I hope you will enjoy the recipe.
can i add the blueberrys to the white alumd sour cream cake that is made using the box mix?
Hi Sarah, I have not tried the recipe using that recipe so I don’t know if it thick enough. Please let us know the results if you decide to give it a try.
What could you replace the sour cream with to make this dairy free? I know how to make buttercream DF (crisco instead, not as buttery and savory but still good), and I would do a lemon filling of some kind besides the cream cheese filling but I’m unsure how to cut out the sour cream or what to substitute it with?
Hi Carrie, Yogurt (Greek is my first choice, plain is fine also) can be a replacement for sour cream in a recipe. I have not tried a dairy free yogurt but there are several on the market. I hope your grocery store carries one of these. Here is a link,
https://www.eatthis.com/dairy-free-yogurt/
If you do a google search, there is information on making your own but buying it would be the easiest thing to do. Good Luck
This is probably a silly question but when making the blueberry syrup, do you strain the blueberries to separate them from the syrup or do you incorporate the blueberries into the frosting? In other words, Does the 1/4 cup plus 2 tbsp of blueberry syrup Mean just liquid or liquid and berries together?
Hi Ben, Not a silly question, now I can see why you might ask. I will add more info in the recipe. We use the liquid and berries together.
I cook the blueberries, water, and sugar on medium heat for about 5 minutes. The volume will reduce and the blueberries will break up a bit as you stir. Depending on how long you cook the berries you will have 1/3 cup maybe a bit more. When you beat this into the buttercream, the berries will be broken up even further. You can see bits of blueberries in the picture of our completed cake. This is another reason we like to use the small wild blueberries. We used Wyman’s Brand. Of course, you could use any blueberries available to you. Hope you enjoy the cake.
Hi
The recipe looks so tempting I wanna try it right away . Just one question.. since I don’t get frozen or fresh blueberries here can I use dried ones .. will the result be the same?
I’m sorry but we have not used dried blueberries so I can’t be sure of the outcome.
I will preface my comment by saying that in general, I prefer frosting to cake. However this cake has made me re-think that position. I was asked to make a lemon dessert for a family get-together. I have several go-to lemon cakes wither with or without glazes, that everyone loves. But I saw this cake and it wowed me. such a vibrant color. And one of my favorite combos – lemon & blueberry. I was a little taken aback at 9 cups of powdered sugar for the blueberry icing, but I followed the recipe exactly. And omigosh! That blueberry frosting is just TOO MUCH! As I said, I love frosting, but I really enjoyed only the first bite of the cake. After that, the lemon cake and lemon cream cheese buttercream filling were overwhelmed by the over-the-top sweetness of the blueberry frosting. The cake and the filling are fabulous. Next time I will use the lemon cream cheese buttercream to frost the finished cake.
Let’s begin with a disclaimer… I am not a baker! However, I am a huge fan of a really good and moist homemade cake. I decided, last night, after stumbling across the recipe that I would give it a try. I love a challenge and baking a cake with 4 different sets of directions (5 if you include assembly,) simply intrigued me. Although there are many steps, everything seemed fairly easy to do. The only thing that I can honestly say is that my blueberry buttercream seemed to taste like powdered sugar. 9 cups was a bit much. So I took the leftover lemon cream cheese filling and mixed it with some of the blueberry buttercream to ice the cake. That was a tweak that I made based on personal preference, but I must say that this cake is divine! I love it. It was definitely worth all the steps and all of the effort. Kudos to the baker!
First off I stupidly tried another blueberry cake recipe from Pinterest and it was a fail. I am new to your site but I have quickly learned to go here first and foremost.
I made the lemon blueberry cake recipe but then just used your lemon cream cheese frosting. I sugared some lemons and blueberries for decorations! Another huge hit! You are making me look very good these days with your recipes!
Thank you for your time, recipes and videos. You have made me fall in love with cake decorating again. I am so glad I found this site!
Thanks so much for your kind words, Sherri! I’m so happy that you liked this recipe- it’s one of our favorites too! Your cake is beautiful with the sugared lemons & blueberries! xoxo
What are some piping tips that I could use instead of tip 21? Would 2D work?
Hi Fiona, any star tip will work for a similar design- the larger star tips like 2D for instance would work but of course they will be larger (and use more frosting).
Ok thanks. I’m making this cake for a new mother in our community. I hope it turns out! If it does I’ll post a pic of it. :)
Here it is! I think it turned out decent enough. This was my first time piping! Hope you like it. I’m definitely not a pro. :)
You did a beautiful job, Fiona! I never would have guessed that it was your first time piping. Thanks so much for sharing a photo!
I plan to make this cake next. I just really love your cakes!! I have a question about overmixing. After adding in the eggs, about how long should I mix so that I don’t overmix the batter? Thank you.
Hi Rachel, Thank you for your nice comment, I’m happy you are going to bake this cake. You will add the eggs 1 at a time and mix until the yellow of each yolk is disappears. At this point begin adding the flour mixture alternately with the sour cream mixture. You will mix the first addition of dry ingredients until the they are blended in, the same for the sour cream mixture and so on until all ingredients are mixed. You may need to mix another minute or until the batter looks smooth. Do not mix above medium speed. I usually mix at number 3 or 4 on my Kitchen Aid stand mixer. If you are using a hand held mixer, you may need to mix a bit longer than you would with a stand mixer. I hope you will enjoy the cake.
Love this recipe! It got rave reviews at my daughter’s Birthday party! Went with a Pineapple fiing instead of lemon, and made it Sofia the First style
Hi CJ, Such a pretty cake and I love the presentation. Thanks so much for posting the picture!
In the recipe where it says “1/3 cup – juice and zest of two lemons”, is the 1/3 cup made up of the juice and zest together, or it is a 1/3 cup of juice and a 1/3 cup of zest? Thanks.
Hi Rachel, 1/3 cup of lemon juice, plus the zest of two lemons ;0)
Thank you so much!
This cake looks delicious! My husband has requested a Lemon Blueberry Cake and this one came up on Pinterest. I was reading through the post above and the batter is mentioned as being thick. Does that make the cake dense or is it light and fluffy? I am just wondering about the texture? Thank you.
Hi Alyssa, The cake batter is thick and this keeps the blueberries from sinking to the bottom of the pan. A thick batter does not make the cake dense. Also, we used frozen wild blueberries that are smaller. We think this is a delicious cake, I hope you will give it a try.
It has been a month since I had time to bake a cake, and I chose this one. I am so happy I did. It is DELICIOUS!! The texture of it is amazing! I was planning to carry the rest of it to a get together with some friends tonight, but now I want to keep it all for myself. :) It is wonderful! I love that the blueberries do not all sink to the bottom but are distributed throughout the whole cake. I did not make the blueberry buttercream but did a cream cheese flavored buttercream instead. I highly recommend this cake. If you are looking for a superb tasting lemon blueberry cake, this is the one.
Hi Rachel! Thanks so much for your feedback, I’m so glad that you enjoyed it!
