Ingredients
  

Main Ingredients

  • 1 cup unsalted butter, softened to room temperature
  • 4 cups powdered sugar (confectioners' sugar), sifted

  • Food coloring Optional

Instructions
 

Preparation

  • In a large bowl, beat the softened butter with an electric mixer until light and fluffy, which takes about 2-3 minutes.
  • Add the corn syrup to the butter and continue to beat for one minute until fully combined.
  • Gradually add the sifted powdered sugar, about 1 cup at a time, mixing on low speed until just incorporated after each addition.
  • Mix in the vanilla extract and 1 tablespoon of milk on low speed until combined.
  • Increase the mixer speed to medium-high and beat for 2-3 minutes until the frosting is light and smooth; adjust consistency with more milk or powdered sugar as needed.
  • If desired, add food coloring and mix until it is evenly distributed throughout the frosting.

Notes

For best results, ensure your butter is truly at room temperature for a smooth, lump-free frosting. Sifting the powdered sugar is crucial to avoid a grainy texture. This frosting can be stored in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 2 weeks; bring to room temperature and re-whip before using if refrigerated.
