I think if you wanted to stay in the same realm as cupcakes/desserts, as far as the "new bubble" goes, it would probably be "Cake Pops". Those are becoming huge now, and only getting bigger. Heck, even Starbucks now carries Cake Pops.
Here is just a general link of what Cake Pops are, if you are not familiar with them: http://www.bakerella.com/pops-bites/cake-pops/ - Basically, just a cupcake/cake on a stick that can have lots of designs around it.
