In your mixer bowl, beat the shortening and butter on medium-high speed until thoroughly blended. Then, lower the speed to low and gradually add the powdered sugar.
Once all the powdered sugar is mixed in, gradually add 1 tablespoon of hot water, one at a time, until you achieve your preferred consistency.
Then, stir in the vanilla extract and beat on medium-high speed for 5-8 minutes until the mixture is light and fluffy.
Notes
• Beat the frosting for the full 5-8 minutes to create a light, fluffy texture.• Room temperature butter blends more smoothly and helps prevent lumps.• Sifting the powdered sugar can help create a smoother frosting.• Add the hot water one tablespoon at a time until you reach your desired consistency.• This frosting pipes beautifully for cakes, cupcakes, and cookies.• The shortening helps the frosting stay stable, especially in warmer weather.
