Preheat your oven to 350°F (175°C). Prepare your round cake pans by greasing them with butter and dusting with flour. Bake two round cakes of your chosen flavor, following package instructions or your favorite recipe. Allow them to cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

With your cooled cakes, slice each in half horizontally to create four semi-circular halves. Arrange two halves from one cake and two from the other on a cake board to form a butterfly shape.

Apply a thin layer of buttercream frosting over the cakes to create a crumb coat. Chill in the refrigerator for about 15 minutes. Once chilled, spread a thicker layer of frosting over the cake for a polished look.

Decorate the wings with various colored buttercream, creating intricate designs that mimic butterfly patterns. Sprinkle with edible glitter and pearls for a vibrant touch.

Transfer the finished cake to a serving platter. Slice and serve this whimsical creation to your guests.
