These are a very refreshing treat to have on a summer day! If you like key lime pie, you will love these!! They are nice for something different as far as cupcakes go:) It is important to have real Key Lime juice, instead of just regular lime juice!

These cupcakes are excellent! They tasted delicious & looked lovely. I followed the recipe exactly but only made 15 cupcakes, and only made half the amount of frosting. Thanks for posting the recipe!
