• Step 1: In a large mixing bowl, beat the softened butter with an electric mixer on medium-high speed until light and fluffy, about 2-3 minutes.
• Step 2: Gradually add the powdered sugar, 1 cup at a time, beating well after each addition. Scrape down the sides of the bowl as needed.
• Step 3: Once all the powdered sugar has been incorporated, add the vanilla extract and beat for an additional 2-3 minutes until the frosting is smooth and creamy.
• Step 4: If the frosting is too thick, add 1-2 tablespoons of heavy cream or milk, one tablespoon at a time, and beat until you reach the desired consistency.
• Step 5: Use the buttercream immediately to frost your desired baked goods, or store it in an airtight container in the refrigerator for up to 1 week.
