My son just turned 7 and LOVES fruit. He wanted a non-traditional cake, so we made it out of fruit — specifically: watermelon, peaches, apples, strawberries, grapes, cantaloupe, and honeydew. We cut out the watermelon first, I think a slightly larger one would have worked a little better. The apples we cut in circles, then cut out the center with metal cookie cutters, and then made a matching watermelon insert. We cut the duck shapes out of cantaloupe, and used toothpicks to hold everything on. To keep the 3 layers from sliding, we inserted bamboo kabob sticks from top to bottom.
