Here's an easy tip for decorating your next cake.... use cookie cutters! I baked my cake, frosted it, and let the frosting harden a little. Then I took out a cookie cutter- mine was a star- and lightly touched it to the top of the frosting which became my outline to trace with a frosting bag. To make a simple, throw away version of a frosting bag, take a ziplock bag, fill it with frosting and cut the tip. A smaller tip will result in smaller piping line or smaller polka dots, and a larger cut corner will result in bigger lines and polka dots. If you have different tips with different shapes, you can drop that into the corner of the baggie before filling it with frosting to give your frosting different shapes like waves and flowers. Have fun and get creative!
