  • 2 1/2 cups all-purpose flour
  • 1 1/4 cups Dutch-process cocoa powder
  • 2 1/2 cups sugar
  • 2 1/2 teaspoons baking soda
  • 1 1/4 teaspoon baking powder
  • 1 1/4 teaspoons salt
  • 2 large whole eggs
  • 1 1 large egg yolk
  • 1 1/4 cups milk
  • 10 Tablespoons vegetable oil (1/2 cup plus 2 tbsp)
  • 1 1/4 cup warm water


  1. Preheat oven to 350 degrees. 

  2. Butter the bottom of 2 9" cake pans, line the bottom with wax/parchment paper, then butter & flour cake pan to prevent sticking and aid in release.

  3. Into the bowl of an electric mixer, sift together flour, cocoa, sugar, baking soda, baking powder and salt.
  4. Attach bowl to mixer fitted with the paddle attachment.

  5. Add the eggs and yolk, the milk, oil, vanilla and warm water. Beat on low speed until smooth and combined, about 3 minutes; scrape down the sides of the bowl as needed.
  6. Divide batter between prepared pans (I found there was more batter than needed for the 2 pans. Be sure not to over fill pans, or you will get a muffin-looking cake that is hard to remove from the pan.)
  7. Bake, rotating half way through, until a cake tester inserted in the middle comes out clean (about 45 minutes).
  8. Transfer pans to a wire rack to cool 30 minutes.
  9. Invert cakes onto rack; peel off the parchment. Reinvert cakes, and let them cool completely, top sides up.
  10. Using a serrated knife, trim the tops of the cake layers to make them level.
  11. Place one layer on a cake plate, spread with 2/3 cup buttercream frosting (or desired filling).
  12. Place other cake layer on top. Spread entire cake with buttercream, swirling to completely cover. Decorate as desired

Recipe Notes

Tip: For chocolate cakes, instead of flour, use cocoa powder to dust the pans

Tip: The easiest way to separate an egg is with you hand: gently catch the yolk and let the whites fall between your fingers

Tip:You can use a whisk to sift Dry Ingredients together.
