After you have baked your cake according to the recipe, here's how to assemble!
Place bowl cake on tray cut side down. Use frosting to adhere cupcakes to bowl cake for feet and bunny tail. Use toothpicks if necessary. Place marshmallow halves, cut sides down, on tops of 2 cupcakes to make heels of feet.
Spread thin layer of frosting over side and top of cake to seal in crumbs. Freeze cake 30 to 45 minutes to set frosting. Then spread the remaining frosting. Follow the directions on either Bunny Butt Cake recipe to get your desired effect!
Happy Spring!
