This cake doesn’t require any intricate steps or complex baking techniques. Just whip up some Rice Krispies Treats mixture, press it into molds, and use the results as building blocks for a unique cake.

Special equipment: For molds you can use baking pans, boxes, mixing bowls, plastic storage containers, or whatever you can think of. Just make sure the molds are clean. Line them with waxed paper, then lightly coat the waxed paper with nonstick cooking spray.

Game plan: After you have removed the mixture from the molds, stack them any way you like and decorate with your favorite candies, like jelly beans or M&M’s (you can even order custom-printed M&M’s on the web). Use store-bought royal icing (a sugar-and-egg-white glaze) to adhere the candies to the cake.
