This cake was actually made for my daughter's birthday in Dec., but I thought it would fit better here. It is a buttercream transfer. I place mine on the cake before I freeze it so that it is smoothed into the top of the cake more. This took several hours. It's my second square cake, still not great at making the square corners, but I think the transfer turned out pretty good. My daughter loved it and that's what counts. Thanks for looking!
