Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, softened
  • 3 ½ cups powdered sugar, sifted
  • 2 tablespoons fresh lemon juice
  • 1 tablespoon lemon zest
  • 1 teaspoon vanilla extract
  • 23 tablespoons heavy cream or milk (adjust for consistency)
  • A pinch of salt

Instructions

  • Beat the Butter: In a large mixing bowl, use a hand mixer or stand mixer to beat the softened butter on medium-high speed for about 2-3 minutes until creamy and pale.

  • Add Powdered Sugar: Gradually add the sifted powdered sugar, one cup at a time, mixing on low speed until incorporated. Increase speed to medium-high and beat until smooth.

  • Add Flavor: Pour in the fresh lemon juice, lemon zest, vanilla extract, and a pinch of salt. Mix until well combined.

  • Adjust Consistency: Add 2 tablespoons of heavy cream or milk and mix on medium speed. If the frosting is too thick, add another tablespoon of cream; if too thin, add a bit more powdered sugar.

  • Final Whip: Beat on high speed for another 2 minutes until light, fluffy, and smooth.

  • Use or Store: Use immediately to frost cakes or cupcakes, or store in an airtight container in the refrigerator for up to 5 days. Before using, let it come to room temperature and rewhip for the best texture.

Notes

  • Zest for Extra Flavor: Using fresh lemon zest enhances the citrusy aroma and flavor—don’t skip it!
  • Sift the Sugar: This prevents lumps and ensures a silky-smooth texture.
  • Adjust Sweetness: If you prefer a tangier frosting, add an extra teaspoon of lemon juice. For a sweeter version, increase powdered sugar slightly.
  • Best Pairings: Pairs beautifully with vanilla, lemon, or berry-flavored cakes and cupcakes.
  • Storage: Keep in an airtight container in the refrigerator for up to 5 days or freeze for up to 3 months.
