I bought the square silicone cup cake liners, but regular cup cake liners inside them and baked up a few dozen cup cakes. Then took them out of the silicone liner and made a cup cake cake. I was hoping to get a "perfect seal" between the cup cakes for my cup cake cakes, and this definitely did the trick! No superfluous frosting fell between the cup cakes. Mini- Roses were made with the 101 tip. the girls on my daughter's team loved them.
