2–4 cups powdered sugar
2 sticks of butter (room temperature)
4 - 6 tablespoons water (or any other liquid of choice)
2 teaspoons pure vanilla extract
Cream butter and vanilla in the bowl of a stand mixer on medium speed for about 3 to 5 minutes until smooth and whipped. With the mixer on low, add powdered sugar one cup at a time and water (or any other liquid) one tablespoon at a time until desired consistency is reached. Beat well until combined.
