Ingredients

  • 1 cup unsalted butter, softened
  • 3–4 cups powdered sugar (confectioners’ sugar)
  • 2–3 tbsp fresh lemon juice
  • 1 tsp lemon zest
  • 1–2 tbsp heavy cream or milk (optional, to adjust consistency)
  • Pinch of salt

Instructions

  1. Beat softened butter in a large mixing bowl until light and fluffy, about 2–3 minutes.
  2. Gradually add powdered sugar, 1 cup at a time, beating well between each addition.
  3. Add lemon juice and zest. Continue beating until fully incorporated and creamy.
  4. If frosting is too thick, add cream or milk 1 tablespoon at a time to adjust texture.
  5. Finish with a pinch of salt to balance sweetness. Use immediately or store covered.

Notes

  • Add a touch of vanilla extract for extra depth of flavor.
  • Use Meyer lemons for a sweeter, floral citrus note.
  • For a firmer frosting (ideal for piping), reduce lemon juice and chill before use.
  • Fold in lemon curd for a silkier texture and more intense lemon flavor.
