DIY castle cake idea to wow them. This is how to make a tower for castle cakes, just paint them with melted colored chocolate or you can spread them with icing and dip them in sprinkles. Attach bottom two cones with chocolate.
(for the future) Easy to assemble pink princess castle cake (just the picture. Two square cakes, two smaller circles, graham cracker door, sugar cones and cake cones for the towers, candy for decoration.) my 2 year old loved it!
