Tips & Substitutions

For a richer flavor, consider substituting half of the cocoa with dark cocoa powder. If you don't have buttermilk, you can make your own by mixing 1 cup of milk with 1 tablespoon of vinegar or lemon juice. Make sure not to overmix the batter to keep the cake light and fluffy. For a different twist, try adding chocolate chips or nuts to the batter.
