Ingredients
Chocolate Cake:
- 2 cups gluten-free all purpose flour blend (285g, I used Bob's Red Mill 1-to-1 Gluten-Free Flour Blend*)
- 1 tsp xanthan gum (omit if your blend already contains it)
- 3/4 cup cocoa powder (75g)
- 2 tsp baking powder
- 2 tsp baking soda
- 1 tsp salt
- 2 cups granulated sugar (410g)
- 1/2 cup vegetable oil (or melted butter if you prefer)
- 1 tablespoon vanilla extract
- 2 eggs
- 1 cup buttermilk (or 1 cup almond milk mixed with 1 tbsp apple cider vinegar)
- 1 cup hot coffee
Chocolate Frosting:
- 2 cups unsalted butter (softened at room temperature (or a 50/50 mix of palm oil shortening and vegan butter))
- 1/4 tsp salt
- 1 1/2 cups cocoa powder (sifted)
- 5 cups powdered sugar (360g, sifted)
- 1 tbsp vanilla
- 1/4-1/2 cup milk (or almond milk)
Instructions
To make the cake:
- Preheat the oven to 350F. Grease two 8-inch round cake pans with butter and dust with cocoa powder or gluten-free flour. Set aside. In a large bowl, add the gluten-free flour blend, xanthan gum, cocoa powder, baking powder, baking soda, salt and granulated sugar.
- Whisk until all ingredients are combined and mixture is medium-brown in color.
- Add vegetable oil, vanilla extract, eggs and buttermilk to the dry mixture and mix with an electric mixer for 1-2 minutes. Scrape the sides and the bottom of the bowl to ensure all of the dry mixture is incorporated.
- Pour in the hot coffee and mix for an additional 1-2 minutes. The batter will be very thin. Let sit for 2-3 minutes to allow the batter to slightly thicken.
- Divide the batter between the two prepared cake pans. I like to use a food scale to ensure that my layers have approximately the same amount of batter.
- Bake at 350F for 30 to 35 minutes or until a wooden pick inserted in the center of the cake comes out clean. Let cool completely before topping with buttercream.
To make the frosting:
- When your cake is either close to cool or completely cooled, add softened butter and salt to a large bowl. Mix for 2-3 minutes using an electric mixer until creamy.
- Add the cocoa powder to the butter mixture and combine using an electric mixer.
- Add the powdered sugar and mix until combined and there are no lumps of sugar or butter.
- Add the vanilla extract and milk (one tablespoon at a time) until the frosting is thick and creamy. It should be thick enough to hold its shape when piped but not so thick that it won't spread.
- If your frosting is too thin, add more powdered sugar. If it is too thick, add more milk a little bit at a time.
- Once the cake has cooled, frost with the chocolate buttercream.
Notes
- This recipe can be made dairy-free by using almond milk and apple cider vinegar in place of the buttermilk. The apple cider vinegar is acidic and therefore helps create a buttermilk substitute. For the frosting, you can use a 50/50 combination of vegan butter and palm shortening.
- If you want to make this recipe into cupcakes, divide the batter between 24 muffin cups and bake for 23 to 25 minutes. I have more tips on how to make chocolate cupcakes here.
