Sweet, creamy, and bursting with vanilla flavor! You'd never guess this fluffy vegan buttercream frosting was dairy free. The best part: you only need a few minutes and four ingredients to make it!
Place the vegan butter into a large mixing bowl and beat it with an electric mixer at high-speed, until creamy.
Beat in the vanilla, followed by 2 tablespoons of non-dairy milk.
Begin beating in the powdered sugar, about 1 cup at a time, making sure to fully beat in each addition before adding more, and scraping down the sides of the bowl as needed.
Continue adding powdered sugar until you're happy with the taste and consistency of the frosting (about 4 to 5 cups total). Less powdered sugar will give you a thinner, creamier frosting, while more will give you a thicker, stiffer frosting.
If you find that you've added too much powdered sugar, thin the frosting with a small amount (1 tablespoon or less) of additional non-dairy milk.
Use the frosting immediately, or store it in a sealed container in the refrigerator for up to 3 weeks, or in the freezer for up to 3 months.
