Ingredients

Vegan Vanilla Buttercream Frosting

  • 1 cup vegan butter, softened at room temperature 190g
  • 1 Tbsp vanilla extract or vanilla bean paste 12g
  • 1 tsp almond, coconut, or lemon extract 4g - optional
  • 3 cups powdered sugar 375g - check the bag to make sure it's vegan!
  • 1 Tbsp alternative milk soy, almond, coconut, or oat (15g)

Instructions

Vegan Buttercream Frosting

  • Beat 1 cup of vegan butter on a medium speed for 30 seconds with a paddle attachment or hand mixer until smooth.
  • Mix in 1 Tbsp vanilla extract or vanilla bean paste on a low speed. If desired, add in an additional tsp of almond, coconut, or lemon extract.
  • Slowly mix in 3 cups of powdered sugar and 1 Tbsp of alternative milk on a low speed.
  • Mix on low for a couple minutes until the ingredients are fully incorporated and the desired consistency is reached. 
  • If the frosting seems too thick, add in additional dairy free milk (1 tsp at a time). If the frosting is too thin, add in more powdered sugar (1/4 cup at a time).
  • Then use as desired! I love using this buttercream to frost cupcakes and cakes.

Notes

How Much Buttercream Does This Make?

1 batch of this vegan buttercream makes about 3 cups and is enough to frost 2 dozen cupcakes.
To frost a 6"-layer cake, 1.5x this recipe. To frost a 7"- or 8"-layer cake, double this recipe.

Making This Vegan Buttercream in Advance & Storage Tips:

  • Make your frosting ahead of time or save any leftover frosting! It can be stored in an airtight container in the fridge for up to a month, or in the freezer for up to 3 months.
  • If you do make this buttercream in advance, be sure to give it a good stir once it thaws to get the consistency nice and smooth again.
  • A frosted cake can last in the fridge for up to a week, or in the freezer for up to a month. The buttercream locks in all the moisture, keeping the cake fresh and delicious!
  • Frosted cupcakes can sit at room temperature for a day or be refrigerated for up to 5 days. Store them in an airtight container once they're made.
