These key lime pie cupcakes are like upside-down key lime pies. The cake (the bottom part) is moist and intensely key lime-flavored (prepare to pucker your lips) and the frosting (the top part) is packed with crushed graham crackers (store-bought or homemade) so you feel like you’re eating a graham cracker crust on top of the cake.

Haven’t You Made Key Lime Pie Cupcakes Before?
I made key lime pie cupcakes back in ’08 and just like it’s a good idea to dust off your shelves every three years (oh, am I supposed to do that more often?), I decided that the recipe could use a little freshening. The original key lime pie cupcake recipe was a huge crowd pleaser, but I wasn’t happy with the graham flavor. I baked the graham crackers into the cake and you couldn’t really taste them.
The wrappers on these key lime pie cupcakes were a gift to me from cupcakewrappers.com. Aside from the fact that I adore the pattern, I LOVE that you can wash the wrappers and use them again and again! Why didn’t someone think of this before?
