  • 1 Cup unsalted butter, softened or 2 sticks
  • 4 cups powdered sugar sifted
  • pinch of salt
  • 1 tablespoon vanilla bean paste or clear vanilla extract* or extract flavor of your choice
  • 2 tablespoons milk


  • Place butter in the bowl of a stand mixer with paddle attachment. Mix on low speed until smooth and fluffy, about a minute.
  • Add the sifted powdered sugar a spoonful at a time over medium-low speed. Keep doing this until all of the sugar is added, scraping down the sides as necessary.
  • Add the salt and stir to combine, add in the vanilla and stir to combine. Add the milk and whip the frosting for 3-4 minutes until light and fluffy.



*Make sure to use clear vanilla if you want a pure white buttercream. Use vanilla bean paste if you love those little black flecks like I do!
