Whip buttercream into tall swirls on top and nestle a paper straw in the center. It looks like a giant milkshake, but with the sweetness of cake.

Split your icing into a few colors, then swirl them with a spatula for a tie-dye effect. Any teen who loves retro vibes will appreciate this.

Cover your frosting with edible glitter or shimmer dust. Add edible disco ball toppers for a flashy throwback everyone will remember.

15. Indulge in cookie dough layers

Spread edible cookie dough between layers of vanilla or chocolate cake. It’s a slice every cookie lover will adore.
