Instructions
Cupcakes
- Preheat the oven to 350 degrees F. Line a cupcake pan with 12 cupcake liners.
- In a large bowl, cream together the butter and sugar until light and fluffy, about 3-4 minutes.
- Add sour cream, vanilla extract and and key lime zest and mix until combined.
- Mix in egg whites two at a time, mixing well after each addition and scraping down the sides of the bowl as needed.
- Whisk together the flour, baking powder and salt in a separate bowl, then add alternately with the milk and key lime juice, mixing between each addition until combined and scraping the sides of the bowl as needed.
- Fill the cupcake liners about three quarters full. Bake for 15-17 minutes, or until the top springs back with a touch or a toothpick inserted in the center of a cupcake comes out clean with just a few crumbs. Cool completely before frosting.
Frosting
- Beat the butter using a hand mixer or stand mixer until smooth.
- Add the powdered sugar in two batches, mixing on low speed until combined.
- Add the key lime zest and 3 tablespoons of the key lime juice and vanilla extract, mixing until combined. Add a pinch of salt. Then add more key lime juice as needed to reach desired consistency.
- Transfer the frosting to a piping bag fitted with a decorative tip. Pipe the frosting onto the cupcakes, then press graham cracker crumbs around each cupcake and sprinkle with additional key lime zest, if desired, and stick a thin slice of key lime on top for decoration.
