When you do as many cakes as we do, you sometimes find yourself using the same techniques over and over. Recently I was asked to come up with a design for a fellow's 75 birthday. He liked Cessna-type planes, but they didn't want a sculpted airplane cake. We didn't feel as though we could make a gumpaste plane, so it was off to the hobby store to find a small model. It was harder to find the plane than it was to put together!! The cake was a 3-tier buttercream cake and we used fondant to make the trees and mountains.
The clouds are where the "new technique" comes into play. I made a batch of marshmallows and piped them into pillowy cloud shapes on a bed of powdered sugar. They came out so perfect! They were fluffy, cloud-like, and delicious!
