Cup of Yum
Frosting
- Combine the butter, cream cheese, juice, salt and zest. Cream together until smooth.
- Add in the powdered sugar, one cup at a time. Mix on low speed until combined. Add in another cup of powdered sugar and mix well. Scrape down the sides often. Once all combined, bump up the speed on the mixer to medium and mix for an additional minute until the frosting is fluffy and smooth.
- Transfer the frosting to a piping bag fitted with a large star tip.
- Once the cupcakes are cool, pipe a large mound of frosting on each cupcake. Top with additional key lime zest and a slice of key lime to garnish.
