  • 12 oz egg whites

  3. Stir the mixture constantly. Check for granules and keep on stirring until no granules are present and the mixture temperature reaches 155 F.
  4. Remove the mixing bowl from the heat and place it in the mixer. Using the whip attachment, whip up the meringue until it is close to stiff peaks and the bowl is cool to the touch.
  5. With the mixer at medium speed, add the cubed butter and keep on mixing until the buttercream becomes thick.
  6. Add the vanilla extract and mix together. Buttercream is ready to use.
