What Does Buttermilk do for Cake Recipes?
The acidity that buttermilk adds to cake batter helps to make cakes even more tender by breaking down the tough strands of gluten. It also adds a subtle tanginess. Many of our cake recipes, including our Lemon Buttermilk Cake, have either buttermilk or sour cream for this reason!

So many! Here are a few of our favorites:

How to Make Chocolate Buttermilk Cake
This moist Chocolate Buttermilk Cake makes three fluffy eight inch layers. This recipe uses the traditional creaming method (rather than Reverse Creaming) method of mixing.
Making the Cake Layers
- In a medium bowl, whisk the flour, cocoa, baking powder, and baking soda. Set aside
- In another bowl, add the buttermilk, oil and vanilla. Set aside
- In the bowl of your mixer, add the softened butter and mix at medium speed until smooth. Gradually add the sugar and continue to mix on medium speed 3 to 5 minutes until lightened in color and fluffy.
- Add the eggs one at a time, mixing until the yellow of the yolk is blended.
- Alternately, add the flour mixture and buttermilk mixture, beginning and ending with the dry ingredients (3 additions of dry and 2 of wet).
- Bake at 350 degrees for 25 to 30 minutes or until a toothpick inserted in the center comes out clean or with just a few crumbs attached. Let cool 5 to 10 minutes and turn out of pan.
Assembling the Cake…
A note about Freezing Cake Layers… After removing the cake pans from the oven, I allow them to cool on the cooling rack for about 5 minutes before flipping them out of their pans and wrapping them individually in plastic wrap, then foil.
(You can use wrapped cardboard cake circles beneath the layers for more stability if you’d like.) – Then I place them in the freezer for at least a few hours (or up to three months!)
Freezing cake layers is completely optional but I’ve been doing this step for years whenever possible as wrapping them while still warm makes them even more moist!
When it’s time to assemble the cake..
Today we’re using a whipped cream filling and chocolate buttercream frosting (yum!)
When using soft cake fillings, it’s a good idea to pipe a dam of frosting around the edge of the cake layer (about ¼ inch-½ inch from the edge) and then fill. This helps to keep the filling contained when it’s time to stack the layers.
In the photo below, I piped a dam of buttercream using a round tip 12 (but you can also just snip the tip from a disposable piping bag.
Fill in with luscious whipped cream!
After filling the cake layers, I frosted with our chocolate buttercream recipe and then decorated using a Wilton 8B french tip. I varied the pressure to get the different sizes of stars.
I also filled in here and there small dots piped from a tip 3 and added a small bead border around the base.
Frosting The Cake with a Smooth Finish…
When I’m going for a smooth look, I like to frost the cake on a turntable and then smooth the frosting with a bench scraper. This is a great place to start.
Then, I freeze the cake for about 10-15 minutes or until the frosting is firm so that I can go back and fine-tune with a hot small angled spatula (heated with very hot water).

Chocolate Buttermilk Cake
This Buttermilk Chocolate Cake is so moist ,fluffy, and perfectly chocolatey!
Ingredients
For the Chocolate Buttermilk Cake
- 1 ½ sticks (170g) unsalted butter, softened ( do not microwave)
- 2 cups (400g) sugar
- 3 large eggs, room temperature - putting cold eggs in a bowl of very warm water will warm them quickly
- 2 cups (242g) all purpose flour
- ¾ cups (69g) unsweetened cocoa powder (not Dutch processed cocoa (measure the sift)
- 1 ½ teaspoons (7g) baking powder
- 1 teaspoon (6g) baking soda
- 1 ½ cups (355g) buttermilk ( if you do not have buttermilk, see Note below)
- 2 teaspoons (8 g) vanilla
- ½ cup (104g) vegetable oil (I use canola oil)
Whipped Cream Filling
- 1 cup (240g) heavy cream
- ¼ (29g) cup powdered sugar
- 1 (4g) teaspoon vanilla
Chocolate Buttercream Frosting
- 3 sticks (339g) unsalted butter, softened (do not soften butter in the microwave)
- 9 cups powdered sugar (icing sugar in UK) (1034g) more if needed. ** For cupcakes, I like to use 8 c. (920g) for a softer frosting
- 1 ½ cups unsweetened cocoa (124 grams) (not Dutch processed, measure then sift
- ½ cup milk (121 grams) more if needed to reach the spreading consistency you like
- 2 teaspoons vanilla (12 grams)
- Notes:
- 1. If you do not have buttermilk this is the substitute. Use a measuring cup for liquid, add 1 Tablespoon plus 2 teaspoons lemon juice or vinegar then fill with milk to the 1 ½ cup mark, stir. Wait 5 minutes and it is ready to use.
- 2.This recipe also works well for cupcakes. Bake standard size cupcakes at 350 degrees for 18 to 20 minutes. Remove from muffin tin onto a cooling rack immediately after baking.
Instructions
For the Chocolate Buttermilk Cake
- Preheat the oven to 350 degrees, grease and flour three 8x2 inch round pans
- In a medium bowl, whisk the flour, cocoa, baking powder, and baking soda. Set aside
- In another bowl, add the buttermilk, oil and vanilla. Set aside
- In the bowl of your mixer, add the softened butter and mix at medium speed until smooth. Gradually add the sugar and continue to mix on medium speed 3 to 5 minutes until lightened in color and fluffy.
- Add the eggs one at a time, mixing until the yellow of the yolk disappears.
- Alternately, add the flour mixture and buttermilk mixture, beginning and ending with the dry ingredients (3 additions of dry and 2 of wet).
- Do not mix above medium speed or over mix the batter.
- Bake at 350 degrees for 25 to 30 minutes or until a toothpick inserted in the center comes out clean or with just a few crumbs attached. Let cool 5 to 10 minutes and turn out of pan.
For the Sweetened Whipped Cream Filling
- Chill the mixing bowl and beaters/ whisk attachment in the freezer for 10 minutes.
- Pour the whipping cream, powdered sugar and vanilla into the chilled mixing bowl, begin beating on low speed gradually increasing to medium high speed.
- The cream begins to thicken (approx. 1 ½ minutes) and soft peaks form....peaks that slightly bend over. Watch closely as this happens quickly. Do not over beat.
- Use immediately as the whipped cream will gradually begin to deflate over time.
For the Chocolate Buttercream Frosting
- Add butter and beat for approximately 1 min. on medium speed. Add vanilla and blend into the butter. Add powdered sugar and cocoa powder.
- Add most of the milk. Begin beating at low speed so you won't have a cloud of powdered sugar in your kitchen. Beat at medium speed 1 minute. Reduce speed to low and beat an additional two to three minutes, adding remaining milk as needed.
This is my favorite chocolate frosting! Recipe can easily be doubled or halved.
This recipe makes approximately 6 cups of frosting.
Looks and sounds delish! :-)
No salt in the cake batter?
Hi Joan, I thought there was enough baking soda in the recipe that the salt could be left out. Hope you will enjoy the cake.
Okay, thanks! I’m anxious to try it.
Hello
Can’t wait to try this recipe.is 2 cups of sugar ok?i don’t like too sweet cakes since I have noticed the salt is not on the recipe.i like the sweetness in the frosting
Hi Candy, I do not find the cake too sweet. The baking soda contains salt and I think the amount of cocoa also offsets the sweetness. I don’t recommend reducing the sugar. I hope you will give it a try. If you do, let us know what you think.
What would you suggest as a filling if it’ll take more than a day to eat this cake?
Hi Laurie- The whipped cream filling will be fine for 2-3 days as long as it is refrigerated–But towards the top of the post we have other favorite fillings listed and any of these will hold up well. If you are not going to refrigerate, I would go with one of the buttercream options (Oreo, Peanut Butter, Chocolate, etc.) Hope that you enjoy it!
Thx!
Can any of your recipes be made for diabetics
Hi Vickie, I am sorry but we don’t have any on the site, we should.
How much batter do you put in each pan? I want to make a smaller cake and trying to calculate how much I can cut the recipe down in size. Thanks!
Hi Carrie, I think this recipe makes 7 1/2 cups to 8 cups of batter. We used three 8×2 inch round pans so I put approximately 2 1/2 cups per pan.
I would love to make this cake for my mom’s birthday, but would need to make it into a flat cake to feed everyone…what size pan would you suggest and bake for how long?
Thanks,
Cindy
Hi Cindy, I forgot to note the number of cups of batter this recipe makes, but I think it is 7 cups. That amount will be enough for a 9×13 sheet pan. Bake at 350 degrees for 30 to 35 minutes. Check at 25 minutes, when a toothpick inserted in the center of the cake comes out clean or with just a few crumbs attached, it is done. If the top of the cake is getting too dark, cover loosely with a piece of aluminum foil.
Can I use cake flour if I don’t have all purpose flour.
Yes, you can use cake flour, just add 4 extra tablespoons cake flour.
Thank you for your quick response.
Hello,can I bake the cakes one at a time?If so how do keep the cake batter?
Hi Kavuyi, It is always best to bake the cake layers at the same time, if possible. Cake batter can be refrigerated but when used later the cake may not rise as high as it should. I think cakes made with a box mix have a bit better result with refrigerated batter than scratch cakes.
Hi,
I would like to bake this cake, but first I would like to confirm that no additional liquid is added to the batter. So many of the chocolate cake recipes on your website call for either milk or buttermilk, and then an additional cup of hot coffee to be added. This recipe does not include any extra liquid other than the buttermilk, so I just wanted to be sure that the recipe is correct as it is written. Thanks!
Hi Marilyn, The recipe is correct as written, I hope you will enjoy it.
Hi, will this cake be suitable to use for a 2 tier cake?
Hi Nasreen, Yes, it will be fine for a 2 tier cake.
Firstly, thank you for some amazing recipes,I think I must have made most of your cakes by now.
I’ve made the chocolate buttermilk cake a few times and the flavour is superb, however I find that it has a tendency to shrink in from the sides of the pans. I understand that all cakes will do this slightly as an indication that they are baked. The last time I made it there was a slight ridge around the edge even though I had baked the layers at the same temp as before. Would appreciate any advice on what I might be doing wrong. Thank you
Hi, I don’t have three cake pans, can I just put all mixtures in one pan.
Hi Tiffany, This recipe makes approximately 7 cups of batter. What size pan are you using? Is it a bundt pan? If it is, don’t fill too full, leave at least a 1 1/4 inch space at the top of the pan.
Hi Rosie, If there is a slight ridge at the top of your cake layers, it could happen if you are using dark colored pans rather than aluminum ones. If you only have dark, you can reduce the oven temperature by 25 degrees and bake the layers a bit longer. Also, it could be that your oven is heating a little hotter than it should. You can check this with an oven thermometer. They are inexpensive and can often be found at the grocery stores. Even if you have a ridge it sometimes just peels off or softens after the cake is frosted and does not cause a problem.
Hi, I’m planning on making a chocolate birthday cake and pairing it with your vanilla buttercream recipe and simple spreadable ganache recipe (whipped) as a filling. Not sure what the difference is taste wise between the two, but would you recommend I use your Chocolate Buttermilk recipe or Chocolate Sour Cream recipe to pair with? Thank you in advance!
Hi Prisca, I think both recipes are very good. The Chocolate Buttermilk recipe as less cocoa (3/4 cup) and the Chocolate Sour Cream recipe has 1 cup cocoa. The Chocolate Sour Cream recipe uses the Reverse Creaming Method of mixing. If you are not familiar with this method you might like to watch Melissa’s video, link below.

Hi, I’ve just made this cake, although it tasted fine it was extremely difficult to cut as the texture was crumbly. Any ideas what could have caused this. Thanks
Rosie, I had trouble with my buttermilk cake as well. It is extremely crumbly and when I tried to put the second layer on top of the first layer, it broke into three pieces. As I was icing the cake, the sides were crumbling apart. Does anyone have any idea what may have caused this? I think the cake is delicious……but it looks terrible. LOL!
@Rosie- I’m sorry that you had this problem! I’m not sure what could have caused this.
@Penny- I’m sorry that you had trouble assembling your cake. I wonder if they still could have been slightly warm? The easiest and safest way to assemble a cake is to have each layer on their own cake board and then just slide (or flip) each layer onto the cake one by one so that they are fully supported as they go onto the cake.
Another good option is to work with partially frozen cake layers. I like to freeze my cake layers individually anyway by wrapping them in plastic wrap followed by foil while each layer is on it’s own foil-wrapped cake board. I talk about this some in my post.
In your case, when it’s time to assemble the cake, just let it thaw partially before unwrapping so that the cake layers are still firm. They are so much less fragile this way for assembling as well as applying the crumb coat.
Also, when applying your frosting, if it seems to be tearing your cake, the frosting likely is a bit too thick- just add a touch more liquid.
After applying the first thin coat (crumb coat), chill in the freezer for about 10 minutes to firm it up before going in with the second coat. The freezer is your friend when cakes are misbehaving and you need to firm things up in order to finish decorating ;0) – Hope this helps!
Melissa, thank you so much – these are all amazing solutions! The cake is delicious, so I’ll try it again using your methods. After the cake had completely cooled, I tried to frost it and didn’t want to have to freeze it, but I realize now that I probably should have stuck it in the freezer! I agree that my frosting may have been a tad bit too thick. Thanks for all of your expert tips. I hope to become a wonderful baker under your tutelage!
I want to make this cake in three 8″ square pans. How much would I need to increase the cake recipe so that I get the same thickness in the cake layers as the round cake layers? Thanks.
Hi Rachel, increasing the recipe by half should give you something similar.
Thank you so much!
