Lemon Vanilla Buttercream

From Sing for your supper blog

• Ready In: 15 mins
• Yields: 1 cup

Ingredients

• 1  cup unsalted butter, softened
• 6 -8  cups confectioners' sugar
• 1⁄4 cup milk
• 1  teaspoon vanilla extract
•  juice of one lemon

Directions

1. Place the butter in a large mixing bowl.
2. Add 4 cups of the sugar and then the milk, vanilla and lemon juice. On the medium speed of an electric mixer, beat until smooth and creamy, about 3-5 minutes.
3. Gradually add the remaining sugar, 1 cup at a time, beating well after each addition (about 2 minutes), until the icing is thick enough to be of good spreading consistency.
4. You may not need to add all of the sugar. If desired, add a few drops of food coloring and mix thoroughly (I used yellow).
5. Use and store the icing at room temperature because icing will set if chilled.
