First, bake your cake in your 13×9 and allow it to cool completely. Use a serrated knife to level the cake top and cut to the shapes shown. Rearrange the pieces to make the head, body and feet of your robot and lay on a large cookie sheet or cardboard covered in foil. Frost in the colors of choice. Slice donuts in half and place them to create connectors for neck, legs and arms.

Tip: place OREO cookies in microwave for 5 seconds and twist to remove cream on one side. Cut a large marshmallow in half and add to each side of the head and use toothpicks and gum drops to make an antenna.
