How to Make the Batter for an All-Chocolate Halloween Cake
The batter is the heart of your cake. Follow these steps for a smooth and fluffy result.
1: Combine Dry Ingredients
- In a large mixing bowl, sift together the flour, cocoa powder, baking soda, baking powder, and salt.

- Stir in the vanilla extract for added flavor.
3: Mix Wet and Dry Ingredients

- Grease the cake pans and line the bottoms with parchment paper.
Bake to Perfection
