Excellent Key Lime Frosting. I piped the frosting onto mini key lime cupcakes and sprinkled then with lime zest. They were a big hit!

Very good, tasty frosting. I used it on Thrown-Together Chocolate Cake. I did need the full 2 tablespoons milk to bring this up to spreading consistency. Thanks for posting!
