Best-Ever Birthday Cake
Celebrate your birthday any day with a big slice of this super-fun sprinkle cake. Sour cream adds a perfect tangy balance to the easy chocolate frosting—and gives this kid-at-heart cake a delicious grown-up twist. The key to a tender crumb is to cream the sugar and butter longer than you think—at least five minutes—to incorporate plenty of air into the batter. We love a mixture of sprinkles to top the cake for an extra-festive look.
