This vanilla buttercream is great as frosting, or as a crumb coating before decoration a layered cake.
- 2 tablespoons pasteurized egg whites
- 100 g confectionary sugar
- 150 g butter, salted and room temperature
- ½ teaspoon vanilla paste
Mix all the ingredients in a bowl, and whip the buttercream until thick and fluffy over a double boiler. I used a saucepan with very hot water, and placed my bowl on top of that. I didn't have it on the stove. It takes some time to get the buttercream nice and fluffy.
