Notes
Marshmallow Stuffed Cupcakes are a classic chocolate cupcake with a soft marshmallow center and a cocoa-based frosting. The cupcakes start with a Devil’s food cake mix baked until just set, then a small portion of the center is removed and filled with a whole marshmallow. A short return to the oven allows the marshmallow to puff and soften before the cupcakes are cooled and frosted.
This recipe works well because the rich chocolate cake provides structure while still staying tender enough to hide the marshmallow filling. Baking the marshmallow briefly after stuffing helps it expand and adhere to the cake rather than remaining firm. The frosting, made from butter, cocoa powder, powdered sugar, cream, and vanilla, is thick and spreadable, balancing the sweetness of the marshmallow with a deeper chocolate flavor. Using reserved cupcake crumbs as a topping adds texture without extra ingredients.
These cupcakes fit easily into everyday home baking since they rely on a boxed mix and straightforward techniques. They can be baked ahead and frosted later the same day. Leftovers store well when covered at room temperature for short periods or refrigerated longer, and the structure stays intact even after chilling.
