Instructions
Preparation
- Preheat the oven to 350°F (175°C) and grease and flour multiple round cake pans.
- In a bowl, whisk together the flour, baking powder, baking soda, salt, and cocoa powder until fully blended.
Mixing Ingredients
- In a second bowl, cream the softened butter, granulated sugar, and brown sugar until airy and fluffy.
- Beat in the eggs one at a time and stir in the vanilla extract.
- Add the dry mixture and buttermilk in alternating additions until the batter is smooth.
Coloring and Filling Pans
- Divide the batter into six bowls and tint each bowl with the food coloring.
- Pour each colored batter into the prepared cake pans evenly.
Baking
- Bake for 25–30 minutes or until the tops are set and a toothpick comes out clean.
- Let the cakes cool completely before frosting.
Frosting and Serving
- Frost each layer with vanilla frosting, stacking as you go.
- For neat slices, chill the cake briefly after frosting.
Notes
To achieve vibrant colors, use more food coloring than you think necessary due to the cocoa's darkening effect. Ensure layers are cool before frosting for cleaner cuts.
