Others feel cozy and classic. A few are best saved for adults. All of them are designed to help you show up with a cake that gets noticed right away.
Classic Green Layer Cake
This cake starts with a standard vanilla batter. Bake it in two or three round pans. Tint the batter lightly so the color stays soft. Frost with matching green buttercream for a clean look.
