Quick Tips for a Great Birthday Cake

Bake a day ahead. Chilled layers are firmer and much easier to frost neatly.
Crumb coat first. A thin base layer of frosting traps crumbs before the final coat.
Level the layers. Trim domed tops so the cake stacks straight.
Match flavor to the guest. Choose a flavor the birthday person actually loves rather than the trendiest one.
Keep a backup plan. Cupcakes or a simple sheet cake are reliable if a tall cake feels risky.
