Only Cakespy, aka Jessie Oleson, could come up with something this incredible (over at Serious Eats): mini cupcakes stuffed inside larger cupcakes for a filled cupcake like no other. Wow wow wow.
But the ultimate cupcake-stuffer? Cupcakes themselves. By embedding miniature cupcakes—frosting and all—inside batter-filled standard-sized cups, you get a surprisingly delightful treat: The baby-cakes, sealed by the moisture of the cake batter, don't dry out, whereas the baked bit of frosting lightly spreads, browns, and adds a rich crunch, making for an overall taste and visual contrast which can't be beat.
