In a large mixing bowl, add the unsalted butter. Using a hand mixer or stand mixer with the paddle attachment, beat the butter on medium speed until it's light, fluffy, and pale in color (about 3-5 minutes).
Gradually add the powdered sugar, one cup at a time, beating on low speed after each addition to prevent a sugar cloud from forming.
Once all the powdered sugar is incorporated, increase the mixer speed to medium and beat for an additional 2 minutes until smooth.
Add the fresh lemon juice, lemon zest, vanilla extract, and salt to the mixture. Beat on medium speed until fully combined, scraping down the sides of the bowl as needed.
Taste the frosting and adjust the lemon juice or salt if needed, depending on your flavor preference.
Once fully mixed, the frosting will have a creamy, spreadable texture. If it's too thick, you can add a teaspoon of lemon juice or milk at a time to thin it out. If it's too thin, add more powdered sugar, a tablespoon at a time, until desired consistency is reached.
Use immediately to frost cooled cupcakes, cakes, or cookies. Store any leftovers in an airtight container in the refrigerator for up to 5 days. Bring it to room temperature and re-whip before using.
