Vanilla Buttercream (Nanette's Go-To Recipe)

Smooth, sturdy, and not too sweet—perfect for filling, crumb coating, frosting, and piping. My favorite trick for a whiter buttercream is included below.

Ingredients

  • 2 cups (452g) unsalted butter slightly cold
  • 6 cups (720g) powdered sugar measured first, then sifted
  • 1 tbsp vanilla extract
  • 2-4 tbsp heavy cream
  • ¼ tsp salt
  • Optional: tiny drop of violet get food coloring (to neutralize yellow tint)

Instructions

  • In a stand mixer fitted with the paddle attachment, beat the butter for 1–2 minutes until smooth but still slightly cool.
  • Measure 6 cups of powdered sugar first, then sift it. Add the sifted sugar ½ cup at a time, mixing on low speed between each addition.
  • Once fully incorporated, add the vanilla, salt, and 2 tablespoons of heavy cream. Beat on medium-high for 4-5 minutes until light and fluffy.
  • Adjust the consistency: add more cream to loosen or a bit more sugar to stiffen.
  • For a whiter finish, add a tiny drop of violet gel food coloring to cancel out the yellow tone from the butter and beat until fully incorporated.
  • Finish by stirring the buttercream by hand with a spatula to press out any air bubbles before using.

Notes

  • Always measure your powdered sugar before sifting. Sifting first can lead to under-measuring and a too-soft buttercream.
  • Makes enough to fill, crumb coat, and frost a 3-layer 6" or 8" cake.
  • For extra flavor, use vanilla bean paste or scrape in the seeds from half a vanilla bean.
  • Store in an airtight container in the fridge for up to 1 week. Let it come to room temp and rewhip before using.
