Frosting Technique

I am seeing a very thickly piped frosting swirl on cupcakes. What is this frosting and how is it applied?

Answer: The frosting used on the cupcakes is a basic butter cream frosting. (You can adjust the flavoring, I don’t use as much vanilla extract.) In terms of the application, you start from the outside of the cupcake to apply the icing. As you squeeze out the frosting, move the icing bag around while applying even pressure until you reach the center of the cupcake. My swirls weren’t exactly perfect the first few tries so I had to give myself a couple of practice cupcakes to start with.
