This is my version of C. Peterson's cactus cake. The "dirt" portion is cake covered with chocolate icing and Wilton chocolate sprinkles. The lizard is rubber. The small cactus does not contain any cake but is just buttercream icing. Royal icing was used for the spikes. The large cake was made using the Wilton ball pan. This was for my husband's birthday, and he loved it. Thanks for looking!
