Funfetti Birthday Cake with Bubblegum Buttercream Frosting

This Funfetti Birthday Cake uses a combination of all-purpose flour, both baking powder and baking soda, sugars, melted butter, eggs, buttermilk, and vanilla, producing a thick batter mixed gently with sprinkles to avoid color bleeding. Baking in two 9-inch pans creates layers that can be frosted once cooled.

The cake’s texture is tender and moist from buttermilk and butter, with dispersed colorful sprinkles adding playful spots. The frosting is prepared by beating softened butter until creamy and gradually adding powdered sugar and bubblegum or vanilla flavoring to achieve a smooth, fluffy topping. Green food coloring is used, but other colors can be chosen to suit preferences.

This cake is ideal for birthday celebrations or festive occasions where both appearance and light bubblegum flavor make it stand out. The frosting complements the cake layers, providing sweetness and a creamy mouthfeel.
