Place room temperature unsalted butter in a mixing bowl. Use an electric mixer on medium-low and beat the butter for 1-2 minutes, until whipped and fluffy.
Add in the powdered sugar and fresh lemon juice (and lemon zest if desired), beat again on low for 1-2 minutes, scraping down the sides of the bowl, until everything is incorporated.
If the frosting is too thick, add a splash more lemon juice, beat until creamy.
Spread on cake or pipe onto cupcakes.
