The castle cake idea. We ordered a large cake from Costco, with a princess on it. (I asked them not to add the other decorations.) We put blue frosting on 4 pointed ice cream cones, and put them, point up, on each corner. Then put jumbo gumdrops around the edge of the castle. We also put blue frosting around the cake for a moat. We cut pieces of fruit roll-ups to make the door, windows and drawbridge. My daughter loved it (she also helped decorate it).
