Notta Cookie is an amazingly simple, and extremely useful, practice cookie! That's it. No baking required to start trying decorating techniques! Practice up your stenciling, painting, piping, lettering, etc. without baking anything. Once you're got it down, you'll be ready to decorate real cookies with less waste. The Notta Cookie resembles a 3-1/2 inch round cookie and is constructed out of tan plastic.
