Key Lime Buttercream

1 cup unsalted butter (room temperature)

1/4 cup fresh lime juice

1/2 tsp salt

5 cups confectioners sugar (pure cane)

1 Tbs lime zest

gel food coloring (optional)

​

In your mixer, first blend your butter and lime juice on low until well mixed. (Don't skip this step because your frosting will separate if you don't blend the lime juice well with the butter)

​

Add salt and blend. Add confectioners sugar and mix on low until well blended. 

​

You can now blend in some gel food coloring to reach the color that you want. I used just a drop of "leaf green". 

​

Hand mix in the lime zest.

​

This pairs well with a white cake or cupcake.

​

*For a stiffer frosting, you can add more confectioners sugar 1/4 cup at a time until it reaches the desired consistency.
