Lemon Buttercream

1 cup unsalted butter (room temperature)
1/4 cup fresh lemon juice
1/2 tsp salt
5 cups confectioners sugar (pure cane)
1 Tbs lemon zest
gel food coloring (optional)

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

Hand mix in the lemon zest.

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