How to Perfect Rhubarb Upside-Down Cake

Use room temperature ingredients: Ensuring your butter and eggs are at room temperature helps create a smoother batter and results in a fluffier cake.

Don’t overmix the batter: Mixing just until combined prevents the cake from becoming dense. Overmixing can lead to tough textures.

Cool before inverting: Allowing the cake to cool slightly in the pan helps prevent breaking when you invert it onto a serving plate.

Common Mistakes to Avoid
