Key Lime Cupcake with Meringue Buttercream

This is the recipe I used. I did use another icing. Also, I made lime curd and injected the cupcakes with that prior to frosting. To be posted later.

Key Lime Cupcakes
These vibrant green cupcakes match the chartreuse walls at Buttersweet Bakery in Atlanta. They also reflect the fun, laid-back vibe of the shop. "We call it retro funk," says owner Charlita Varner.
