Baking Science: Why This Recipe Works

This recipe uses oil instead of butter in the cake, which ensures long-lasting moisture. Buttermilk provides acidity that activates baking soda and tenderizes gluten. Hot water helps bloom the cocoa, intensifying flavor.

Mint Chocolate Cake – Add 1 tsp peppermint extract.
Orange Chocolate Cake – Add orange zest to batter.
Raspberry Chocolate Cake – Add raspberry filling between layers.
