I made this Birthday Slumber Party Cake Design for my daughter on her 10th birthday, following many of the instructions on this site. I baked a 9×13 chocolate cake, covered with buttercream frosting and then fondant.
I used homemade marshmallow fondant for the bedspread and colored gumpaste through my garlic press for hair. The trim around the bedspread is fruit roll up and the other decorations are skittles. It was a big hit!
