We are so happy to share this delicious scratch Blueberry Cake with you! Frosted and filled with Lemon Cream Cheese Frosting, this moist blueberry cake is bursting with flavor.

This moist blueberry cake with lemon cream cheese frosting has amazing flavor!

If you love blueberry desserts, you're going to fall in love with this cake, which not only has blueberry puree in the cake batter, but is speckled with whole blueberries, ensuring wonderful blueberry flavor in every bite.

What Pairs Well with Blueberry Cake?

Blueberry and lemon are always a winning combination! As soon as we tried the blueberry cake layers, we knew that we wanted to incorporate a lemon frosting.

We actually have a Lemon Blueberry Cake in our recipes section which is a lemon sour cream cake with blueberries folded into the batter. We love that recipe also, but today's recipe incorporates even more refreshing blueberry flavor! 

For today's blueberry cake, we are using a Lemon Cream Cheese Buttercream, which is a cross between buttercream and our usual lemon cream cheese frosting. It pipes great, covers the cake well, and most importantly, is delicious!

This blueberry layer cake would also taste great with: our classic lemon cream cheese frosting, blueberry buttercream, lemon buttercream, vanilla buttercream, or cream cheese frosting!

How to Make Blueberry Cake 

What makes this cake extra special is that it has pureed blueberries mixed into the batter as well as whole blueberries. There's a lot of great blueberry flavor happening here- it really is the BEST blueberry cake (it's also the only blueberry cake recipe we've made, haha) but it is SO good- we are excited for you all to try it!

Cooking Down the Blueberries

The purpose of our blueberry reduction is to give us the most blueberry flavor without having to add too much additional liquid to the cake batter. 

It's best to go ahead and cook down your blueberries as the first step. Measure out 1 ½ cups (198g) blueberries. If using frozen blueberries it is best to allow them to thaw before they are pureed (or if in a hurry, run them under warm water to thaw more quickly). 
 
In a saucepan add the pureed blueberries and ¼ cup water.  Cook over medium high heat until they are reduced to ¾ cup (181g).  If you happen to reduce too much, just add water to reach the ¾ cup mark.  
Allow the reduced blueberries to cool.  (The blueberry reduction can be prepared the night before and be refrigerated).   

 

Preparing the Blueberry Layer Cake Batter and Baking

 
Grease and flour three 8x2 inch round cake pans. (I also like to line my pans with circles of parchment).
 
In a medium sized bowl, add flour, baking powder, baking soda and salt.  Whisk to blend for 30 seconds and set aside.
 
Next, in another bowl, combine the sour cream, oil, and blueberry puree. Blend with fork and set aside.
 
 
In the bowl of a stand mixer, mix the butter until smooth. Gradually add the sugar and mix on 
medium speed 3 to 5 minutes or until fluffy & lightened in color. You may need to mix a little longer if you are using a hand mixer.
 
Add the eggs one at a time mixing until the yellow of the yolk disappears.
   
Next, add the flour mixture and the sour cream mixture alternately, beginning and ending with the       
flour mixture (3 additions of dry ingredients, 2 additions of wet ingredients).
Next, add a bit of pink coloring gel at this time.  I added just a small amount to brighten the color. The batter will change from the natural blue-grey shade of the batter to a brighter, blue-purple shade. Mix until 
combined and smooth.  Do not mix above medium speed or mix too long.
 
Next, Fold in ½ cup blueberries. The thick blueberry cake batter is great because it prevents the blueberries from sinking to the bottom of the pan.  
 

Bake at 350 degrees for 22 to 25 minutes or until a toothpick inserted into the center of the cake comes out clean or with just a few crumbs attached. (Bake time may vary and so keep an eye on your layers in those final minutes)!

Decorating the Blueberry Layer Cake

After filling and frosting the blueberry cake layers on my cake pedestal, I rotated it on a turntable as I smoothed around the sides using a metal bench scraper.

Even when I'm texturing the sides of the cake as I did for our blueberry cake, I try to get it fairly smooth first so that I have an even amount of frosting all the way around.

By the way, these cake layers are dark- you may need to apply the frosting slightly thicker than usual for full coverage.

Also, keep in mind that cream cheese frostings are softer than typical buttercream frostings. Because of this, you may need to pop your frosting bowl into the refrigerator for several minutes before starting the process and also if it becomes too soft to work with.

If the frosting on your cake at any time seems too soft, chill it in the freezer or refrigerator for about 10-15 minutes to firm everything up.

Texturing and Final Details

After smoothing the final coating of frosting around the sides and top with my bench scraper and spatula, I went in with my small offset spatula and textured the frosting.

Then, around the top edge, of the cake I added blueberries, small lemon wedges, and frosting stars piped with a 6B french tip as well as a star tip 21.

Is it necessary to add coloring gel to the batter?

I don't often add coloring gel to cake batter but for this blueberry cake, it really makes a difference!

The natural color of the cooked down blueberries tints the cake batter a light shade of blue-grey. Adding a touch of pink coloring gel (we used a small amount of Wilton Rose) really brightens up the batter to the shade of purple/blue that we associate with blueberries.

It's a beautiful shade and we love the flecks of blueberry as well as whole blueberries that you can see in every slice!

For the Lemon Cream Cheese Buttercream

  • 3 sticks unsalted butter, slightly softened (339g)

Instructions

For the Blueberry Cake

  • It is good to prepare the blueberries first.  Measure out 1 ½ cups (198g) blueberries. If using frozen blueberries it is best to allow them to thaw before they are pureed.  In a saucepan add the pureed blueberries and ¼ cup water.  Cook over medium high heat until they are reduced to ¾ cup (181g).  If you happen to reduce too much, just add water to reach the ¾ cup mark.  
  • Cool the reduced blueberries until cool.  Can be made in advance and refrigerated.   
  • Preheat the oven to 350 degrees, grease and flour three 8 inch x 2 inch round cake pans.
  • In a medium sized bowl, add flour, baking powder, baking soda and salt.  Whisk to blend for 30 seconds.   Set aside.
  • In another bowl, combine the sour cream, blueberry puree and oil. Blend with fork and set aside.
  • In the bowl of your mixer, mix the butter until smooth, Gradually add the sugar and mix on  medium speed 3 to 5 minutes or until lightened in color and fluffy.  If using a hand mixer, you may need to mix a bit longer.      
  • Add the eggs 1 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 the       flour mixture (3 additions of dry ingredients, 2 additions of wet ingredients).   
  • Add pink coloring gel at this time.  I added just a small amount to brighten the color.  Mix until combined and smooth.  Do not mix above medium speed or mix too long.
  • Fold in ½ cup blueberries
  • Bake at 350 degrees for 22 to 25 minutes or until a toothpick inserted into the center of the    cake comes out clean or with just a few crumbs attached. Keep an eye on it, ovens can bake differently.     
  • Let cool in pans 5 to 10 minutes, then turn out.

Lemon Cream Cheese Buttercream

  • 1.  Add the slightly softened  butter in the bowl of your mixer and mix until smooth
  • 2. Add pieces of cream cheese to the mixing bowl.  The cream cheese should be soft enough
  • that it combines easily into the butter mixture. 
  • 3.  Gradually add the powdered sugar. Add the lemon juice, lemon extract and zest.  Do not
  • over mix. The longer it is mixed the softer it becomes.  If it becomes too soft, refrigerate 
  • 10 minutes or so and it will firm up.
  • Makes about 5 cups of frosting.

Notes

Substitution for cake flour

Using all purpose flour (plain in the UK) for each cup of flour in a recipe, remove 2 Tablespoons of flour replace with 2 Tablespoons cornstarch (cornflour in the UK).  This recipe has 3 cups of flour so you will measure out 3 cups of all purpose flour, remove 6 Tablespoons and replace with 6 Tablespoons cornstarch, whisk to blend.       
*This recipe makes approximately 7 ½ cups of batter.

  1. Has anyone had any luck making this cake vegan? For example, using vegan butter, flax eggs, vegan sour cream? I find cakes to be pretty forgiving to these modifications but I wanted to ask first. Thanks!

  2. The instructions for the icing mention lemon extract, but I don’t see it listed in the ingredients, so I don’t have any on hand . I hope the icing turns out just as well without it!

  3. Hi Denise, Your frosting should turn out very well without the lemon extract. We decided to make it an optional ingredient for stronger lemon flavor but forgot to add it to the list. Let us know what you think just using lemon juice and zest.

    1. Hi Lauren, This recipe make 7 1/2 cups batter. Leaving the recipe as written, you can use two 8 inch round pans that are 2 inches deep. You will need to increase the baking time a bit so keep an eye on it. We use 3 pans because we like having thinner layers plus 2 layers of frosting.
      The cake will be just as good baking in 2 pans. The cake will be done when a toothpick inserted into the center comes out clean or with just a few crumbs attached. Hope you will enjoy the recipe.

      1. Hi! I’m new to baking. I’m going to use this recipe for my sons first birthday (he’s obsessed with blueberries) and I’m doing a two tier 5 x 2 round. I’m assuming I’ll need to adjust the cooking time? I know I’ll have too much batter if I make it as is, but would you suggest cutting cook time?

        1. Hi Jordan, We have not baked in 5x2 inch pans. Use this as a guideline -- a 6x2 inch round pan can hold 2 cups of batter, baking at 350 degrees the baking time will be 25 to 30 minutes. Your baking time will be less but I am not sure how much less. The cake will be done with a toothpick inserted into the center comes out clean or with just a few crumbs attached.

    1. Hi Monique, We do not sift the cake flour but it is fine to do so. First measure then sift. We measure by spooning flour into a measuring cup then leveling off with a knife. We add the dry ingredients to a bowl then whisk for at least 30 seconds to blend the dry ingredients . The whisking also aeriates the flour. I hope you will enjoy the recipe.

  4. My daughter requested a blueberry cake for her birthday and your recipe looks delicious! I would prefer to make it in a 9x13, or larger if necessary. Have you tried that, and how long do you suggest baking?
    Thanks so much?

    1. Hi Debbie, This recipe makes approximately 7 1/2 cups of batter. We have not baked this cake in
      a 9x13 pan but I think it would be fine to do so. With only 7 1/2 cups batter the cake will
      probably be under 2 inches high, the frosting will add more height. Bake at 350 degrees for 35 to
      40 minutes, check at 30 minutes. The cake will be done when a toothpick inserted into the center comes out clean or with just a few crumbs attached.

  5. An easier way to make substitute cake flour is to put the two tablespoons of cornstarch in your cup first and then fill with flour

  6. 5 stars
    My daughter loves blueberries, so I made this cake (with a different icing) for her first birthday and was shocked at how delicious it was! She enjoyed it too.
