The Frosting is already prepared for you to just open and use. It comes in a pastry bag, and already has the tip in the bag, so all you do is open it and use the Frosting/Icing. The Chocolate comes in Chocolate and Chocolate Fudge, either one is fine to use. I used Pillsbury, but you can use another Brand if you prefer. The Neon Lime Green Food Coloring Gel is Wal-Mart Brand, but any Brand you prefer may be used.
