I was asked to make a cake for a Breast Cancer Awareness bowling league. I used store-bought icing tinted with Wilton paste coloring for the flesh and homemade buttercream icing for the rest.
I thought the buttercream might be too rough looking and might seem less realistic. I outlined the ribbons with a writing tip and then filled in using a simple star tip, that way there was a distinct line and border.
My kids thought is was the funniest cake ever and I heard the folks at the bowling alley liked the Breast Cancer Awareness Cake too!
