Ingredients for Easy Chocolate Cake with Chocolate Buttercream Frosting

Ingredients in bowls on a counter top.
  • Dry ingredients – you will need all purpose flour, baking soda, baking powder, and salt for baking your chocolate cake.
  • Unsweetened cocoa powder – I like to use dutch process cocoa for a rich and smooth chocolate flavor. If you don’t have dutch process cocoa on hand though, regular cocoa powder will work fine.
  • Sugar   you will need granulated white sugar for the cake batter and powdered sugar for the frosting.  
  • Vanilla extract –  gives depth of flavor to your chocolate cake. You can also use vanilla bean paste instead.
  • Eggs – you will need 2 large eggs for your cake. Allow your eggs to come to room temperature first, as they will blend into your wet ingredients much more smoothly.
  • Buttermilk – If you don’t have any buttermilk on hand, you can easily make some from regular milk and vinegar. Simply add 1 Tablespoon of white vinegar to a liquid measuring cup and add enough milk to reach the 1 cup line. Stir, then allow the mixture to sit undisturbed for 5 minutes before adding to the recipe.
  • Vegetable oil – you will need 1 cup vegetable oil for your cake. You could also use canola oil, but  I don’t recommend replacing this with butter or any other oils. 
  • Hot water – is used to thin out the batter.
  • Butter – I recommend using unsalted butter. You will need one stick softened to room temperature.
  • Milk –  is used for making the chocolate buttercream frosting. I like to use whole milk or 2%. You could also use half and half or heavy cream.

While the cakes are cooling, prepare the frosting. Combine the softened butter, powdered sugar, cocoa powder, vanilla extract, and milk in a large mixing bowl. Beat over medium speed with an electric mixer until frosting is nice and creamy. Add more milk or powdered sugar until desired consistency is reached.

Invert one cake layer onto a serving plate or cake stand. Spread a small amount of frosting evenly over the top of the cake then top with the second layer. Spread the remaining frosting over the top and sides of the cake. Slice and enjoy!

Tips and Notes

  • Use room temperature ingredients. Using room temperature eggs and buttermilk will help your ingredients to incorporate smoothly. If you haven’t had time to let your eggs come to room temperature, simply place them in a bowl of warm water for five minutes before adding to the chocolate cake batter.
  • This can also be made in a 9×13 inch pan. Prepare as directed then bake in the preheated oven for 32-36 minutes, or until a toothpick inserted in the center comes out clean.
  • To make this recipe into cupcakes, you can use my Buttermilk Chocolate Cupcakes recipe. The frosting for those is an insanely delicious whipped chocolate ganache that is so good!
  • For a lightened up chocolate cake recipe, try my Skinny Chocolate Cake made with a cake mix and Greek yogurt. And if you’re in need of a gluten free option, try this Gluten-free Chocolate Cake recipe.
  • Store any leftover cake in an airtight container at room temperature for up to three days.

Why use buttermilk when making chocolate cake?

Buttermilk is a wonderful choice for baking, especially in cakes. It lends a rich depth of flavor, and also creates a soft and fluffy texture. This happens because of a chemical reaction between the acid in the buttermilk and the gluten in the flour. Bottom line: if you like a soft cake with exceptional flavor, choose buttermilk! And if you don’t have any buttermilk on hand, it’s super easy to make with ingredients that you likely already do have!

What if I don’t have buttermilk on hand?

Homemade buttermilk is really simple and quick to make if you don’t have any. All you need is plain white vinegar and regular milk, preferably whole or 2%. Simply add 1 Tablespoon of white vinegar to a liquid measuring cup and add enough milk to reach the 1 cup line. Stir, then allow the mixture to sit undisturbed for 5 minutes before adding to your recipe. That makes 1 cup of buttermilk, which is how much you need for this recipe.
