For a unique and crunchy birthday cake, try making a caramel popcorn cake. Start by baking a layer of caramel-flavored cake and letting it cool. Whip up some caramel frosting using butter, powdered sugar, and caramel sauce. Frost the cake with the caramel frosting and press caramel popcorn onto the sides of the cake. Top the cake with more caramel popcorn and drizzle caramel sauce over the entire cake. This cake is a delightful combination of sweet and salty flavors, and the crunchy popcorn adds a fun texture.
