The warm sweet potatoes lying under a gooey, toasty layer of marshmallows...mmm! It's the best part of Thanksgiving, after the stuffing, of course.

I asked my sweet-potato-hating-boyfriend what he thought about the idea of these cupcakes, and he said in the most grossed out voice he could muster "EWH".

"Okay, pretend like you like to eat that at Thanksgiving. Now what do you think about them?"

He thought they could be "interesting". But he didn't sound convinced.

So when I brought him a cupcake to taste, scared he wouldn't even want to try it, I couldn't believe his reaction.  I don't think I have ever seen his eyes light up so much! He may or may not have cussed while telling me how good they were. And it didn't even have the frosting on yet.

If I can convert Paul onto the sweet potato side with these cupcakes, my work is done. Simply put, these were amazing! The cupcakes are fluffy, moist, and the perfect texture. They're full of brown sugar and spice. The frosting is made from scratch, and the frosted cupcakes are toasted to perfection in the broiler.

The recipe makes 15 cupcakes, and the marshmallow recipe makes enough to generously frost them all, with maybe a few spoonfuls left to eat straight out of the bowl. We dare not waste precious home made marshmallow fluff.

Don't let the idea of the from-scratch marshmallow fluff scare you! It's so easy. You just mix the egg whites, sugar, and cream of tartar in a (heat-proof) bowl that sits on top of a pot of simmering water. You whisk it until the sugar dissolves, and then transfer the liquid to your mixer to whip it into shinning shimmering splendor. 

Did I just quote Aladdin? I sure did. And then I went on Youtube to find the video of that song, to which I shamelessly belted the whole thing out. 

But really, these cupcakes will show you a whole new world. Excuse me while I go watch Disney movies and eat the rest of these cupcakes!
