This sounds too easy to be true!
First, you start with a regular chocolate or devil’s food cake mix. Any brand will do. You’re going to mix it according to the directions (but I always add a TBS of vanilla to the mix because I swear it tastes better that way.) You’ll also need some regular size marshmallows and some chocolate frosting.
After you mix the cake batter, fill cupcake liners 1/2 way with batter. Push a whole marshmallow into the center, then bake according to the directions.
When they are done, you’ll have a crater in the middle. It looks gross right now, but it’s worth it. Pinky promise! As soon as they come out, push a fresh marshmallow into the center, then pop them back into the oven for about 2 minutes. You want them to get all melted and fill in the hole.
When the come out, just know ahead of time that the marshmallow will fall a bit. You’re going to have a small dip in the top. It’s all good – don’t stress out :)
Use a spoon to help coax the cupcakes out of the pan – gently – and put them on a cooling rack to cool.
Then, frost your cupcake as normal. It’s going to cover up all the ugly, but also add another level of yum.
They’re like covert cupcakes – they look totally normal on the outside, and then BAM! the inside takes you by surprise (unless you know it’s in there!)
