  • 6 tablespoons (3/4 stick; 85 g) unsalted butter, at room temperature, cut into small pieces
  • 3 cups (270 g) icing sugar, whisked before measuring (plus extra as needed)
  • 3 tablespoons lactose free whole milk, 2%, 1% or fat free (plus extra as needed)
  • 3/4 teaspoon vanilla essence


  1. In a large bowl with an electric mixer on medium-high speed, beat butter until creamy, about 2 minutes. Add half of the icing sugar gradually, beating until light and fluffy, about 3 minutes, scraping down the bowl once or twice. Add remaining sugar, milk and vanilla and beat on high speed until silky smooth. If it is too thin, add a little more icing sugar. If it is too thick add a little but more milk. Frosting is now ready to use and best if used immediately.
  2. Frost cupcakes or fill and frost cake once they are completely cooled. You can use a small offset spatula to create a casual look to apply frosting or use a pastry bag and star tip to create beautiful swirls.


  • The secret to super-smooth frosting is to beat it A LOT. It might need many more minutes than you expect, especially if any of the ingredients were cold. Just keep beating and you will be rewarded with creamy smooth frosting.
