I have been using this recipe for years. It is a great buttercream frosting with a light and airy texture.
1 cup (2 sticks) butter, softened
3-4 cups confectioner sugar
¼ teaspoon salt
1 tablespoon vanilla extract
Up to 4 tablespoons milk
Beat the softened butter for 2 minutes with the whisk attachment of a stand mixer.
Turn the mixer on lowest speed and add 3 cups of confectioner sugar
When the mix is blended, turn to medium speed, add vanilla, salt and 2 tablespoons milk, beat for 3 minutes
Add the remaining sugar or milk as needed. I did add all the sugar and milk to my mix.
Tips- do not microwave your butter, soften to room temperature.
You may want to beat the mix for a few minutes until it incorporates. I mixed it for about 3-4 extra minutes just to get the perfect taste and texture
