Coconut Cupcakes with Key Lime White Chocolate Frosting

I know it might seem a bit ridiculous with the amount of coconut and key lime we have here at num’s the word, but I don’t see an end in sight. Once again, this is one that I’m super excited to share with you.

These cupcakes are seriously my favorite cupcakes that I have ever made. I think. Well, maybe I shouldn’t make such blanket statements. I’ve made some pretty darn good cupcakes. But these are definitely up there with the good ones.

They are a combination of some of my favorite flavors and in some of the best ways. The cupcakes are moist and have a fantastic coconut flavor. The frosting is amazingly flavorful with key lime and an added awesomeness of melted white chocolate.

I’ve made these a couple of times and they were a hit every time.

      Thanks Emily! We were really excited with how the pictures turned out too! The light in the kitchen is my favorite part of my house, but sadly we’re moving and I’m really hoping to find something similar!
