Makes
enough frosting for about a dozen cupcakes if frosted; about a half-dozen if piped.
Author Notes
Simple but unbelievably delicious, refreshing, and addicting. Lime and cream cheese were meant to go together. —Cynthia Chen McTernan
Test Kitchen Notes
This icing was worth breaking down and buying a Microplane zester for (albeit a clearance one from Target). The lime-y flavor was great but not overpowering. I essentially used the cupcakes I baked for this recipe as frosting vehicles -- arguably the best way to eat cupcakes. The recipe is very easy. I highly recommend it. —Rachel

Ingredients
-
4 ounces
cream cheese or Neufchatel cheese, softened
-
1 tablespoon
butter, softened
-
1 1/2 cups
confectioners' sugar
-
1 teaspoon
lime juice, or more depending on resulting thickness of the frosting
-
1 teaspoon
lime zest
Directions
-
If using an electric mixer, simply combine all the ingredients and beat until fluffy and smooth.
-
If making by hand, cream together cream cheese and butter until very smooth. It will help greatly if the cream cheese and butter are quite soft beforehand.
-
Add confectioners' sugar 1/2 cup at a time, beating until incorporated after each addition.
-
Finally, add lime juice and lime zest and beat again until smooth. If the frosting is too soft, add more confectioners' sugar, 2 tablespoons at a time, until frosting is the right stiffness. If it is too stiff, you can add more lime juice a few drops at a time.
