Great idea! To create easy to decorate pull-apart cupcake cakes, place the liners into shaped pans. Then, pour the cupcake batter in and bake. The cupcakes will conform to the pan and create different shaped cupcakes that are still easy to separate.
SERIOUSLY.. if you EVER use a piping bag, this will CHANGE YOUR LIFE. I used her technique last night, and not only was loading/unloading the bags easier, I actually used a LOT less frosting due to waste and clean up was so easy I couldn't believe it!
