Lime Buttercream Frosting
Ingredients:
4 cups confectioners’ sugar
1 stick unsalted butter, at room temperature
1/8 tsp. salt
3 tbsp. lime juice
green food coloring (optional)

Directions:
Add all ingredients to a stand mixer fitted with the paddle attachment and mix on low until combined. Turn the speed to medium-high until the icing is light and fluffy. Use water to thin the frosting if necessary (I used about 2 tbsp). Add the icing to a pastry bag or use a spatula/knife to frost the cupcakes.

Be sure to check out the cupcake recipe after the jump that features a touch of Grand Marnier and lime zest.  Lovely!
