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.
