I printed a picture on a transformer on line and cut it out for this Transformers Birthday Cake. I placed it on the buttercream once it crusted and traced it with a tooth pick. Then I just filled in the inside according to the picture.

The mask was very easy to trace and fill in. If you have no drawing skills I recommend the mask! I made the inside rainbow colored by dying the cake mix. It was a hit! I used curly ribbons on the corners for decoration.
