Do you sell this cake? No, just for fun Share a little about the materials, processes, and techniques used to create this cake Jaxon's favorite is "Angry Bird" so for his birthday this year I made him Angry Bird cake toppers. I used fondant and gum paste to sculpt the birds and used rice crispy treats to form the sling shot. It took me two days to do the sculpting as I wanted to do it in stages. I made sure that everything was dried and set before I added the facial features.
