This Potbelly Princess Slumber Party Cake was so much fun to make. I baked a boxed cake in a 9×13 rectangular pan and frosted it with white buttercreme frosting.
I sliced Twinkies in half and used them for the body. I used vanilla wafers for the face and gel icing for the eyes, hair and mouth. The pillows are made of large marshmallows. Each girl has a candy princess crown.
