This cake was test run for another textbook cake I'm doing this weekend for a college graduation. everything is edible, The books are lemon cake with lemon filling. I did the drawing and printed it on a edible frosting sheet, the apple is fondant. Since this was an actual cake I ended up sending it to my daughter daycare for everyone to enjoy for teacher appreciate week I'm going to do another one for more practice and send it to to school for my son's teacher.
