  • ¾ cup unsweetened cocoa powder
  • 2 tsp baking powder
  • tsp baking soda
  • 1 tsp salt
  • 1 cup milk whole or 2%

Step 1: Preheat & Prep

  1. Beat softened butter until creamy.
  2. Add cocoa powder, powdered sugar, vanilla, and salt.
  3. Add milk 1 tablespoon at a time, beating until smooth and spreadable.
Step 5: Assemble
  1. Place one cake layer on a serving plate.
  2. Spread frosting evenly over the top.
  3. Add the second cake layer and frost the top and sides.
  4. Decorate with sprinkles, chocolate shavings, or berries if desired.
