I used a really large round tip and piped on the kernels. Then I let them crust, lightly tapped down any pointy peaks. Then I had to take a tool and make the criss cross pattern. This was the most time consuming. I had to wipe off the tool after each kernel, as there was BC on it and then dip it in a cornstarch/powdered sugar mixture. Cause once you push past the crusted outer layer, it of course was soft underneath. There were roughly 30+ kernels on each cupcake times 24 cupcakes! It took about 4 hours total for the cupcakes alone. Then I airbrushed some yellow for the "butter." I will be charging alot more for these if ever asked to make them again!!!
