I am making an Angry Birds cake for my son using the soccer ball pan. I want to make the beak and top feathers out of rice krispie treats but am unsure how to attach the beak without it falling off...have had problems with this in the past.

When I attached the beak and feathers to my AB, I first inserted toothpicks. Then I put a little bit of melted candy melts on the back. Push the beak/ feathers with toothpick(s) into cake and hold in place to let candy melt harden. Hope this helps.

I agree- melted chocolate. I keep a can of "air" around to speed the drying time of the chocolate.
