This classic birthday cake features a tender, moist vanilla crumb and a cheerful rainbow sprinkle buttercream. It’s a simple, crowd-pleasing recipe that comes together in about an hour with basic pantry ingredients.
Room temperature ingredients are crucial for proper emulsification. Don’t overmix the batter once flour is added. Chill the cake before final frosting for a smoother finish. For clean slices, chill the cake for 20 minutes before cutting.
