Graham cracker cupcakes with key lime filling. Sounds tasty right? Let me add in one additional detail: lime cream cheese frosting. Okay. Stop licking your computer screen. It is time to make some of these treats! The batter consists of graham cracker crumbs, sugar, flour, and several other traditional ingredients. The filling is made of three things: key lime juice, egg yolks and sweetened condensed milk. Top with the lime cream cheese frosting (cream cheese, butter, lime extract and powdered sugar) and serve!
