Cupcakes, Cupcakes, 2500ºF

Being the happy new owner of a Blazer Micro Torch that I got for silversmithing, I'm finally giving in to some torch-in-the-kitchen recipes I've been ignoring or sticking under the broiler. Plus, with Gail Gand's MORE cupcake shop opening shortly in Chicago, I've been kind of cupcake-crazed. What does this mean? Chocolate cupcakes with a fluffy mound of homemade marshmallow frosting, browned to a crisp.
All you need is a good marshmallow icing recipe, some chocolate cupcakes, (maybe chocolate and pink peppercorn?) and a torch.
