Comments: A pyramid-shaped cake made from marshmallow treats is a delicious dessert for a birthday party or baby shower. Martha, her nephew Charlie, and her friend Emily Kelly use several types of cereal treats to build their cake. For the base of the pyramid, they use a recipe provided by Marthas daughter Alexis for confetti squares - cookies made from Fruit Loops, Capn Crunch, Rice Krispies, and marshmallows. To create the middle and top layers, they use Cocoa Krispies and Rice Krispies Treats. Wrapped in cellophane and tied with a ribbon, this colorful layered cake also makes a delightful party centerpiece.
