That sounds like an awesome recipe for themed or even bookish events --- "Broken Glass" Cupcakes!The recipe for the "glass" is essentially one for caramel. The trick is to cook it for a shorter amount of time than usual so it stays clear.
Candy Corn Cupcakes - This is my new go-to recipe for white cake and vanilla frosting. Bakery quality in the best way. My only change was to sub of the butter in the frosting for shortening because I ran out, but I think that made the texture even better.
