How to Make Mr Brown's Italian Meringue Buttercream

  1. In a heatproof bowl, whisk together 1 cup (200g) granulated sugar and 1/2 cup (120ml) water.
  2. Cook the sugar mixture over medium heat, stirring constantly, until it reaches 240°F (115°C) on a candy thermometer (soft-ball stage).
  3. While the syrup cooks, beat 4 large egg whites and a pinch of salt in a separate bowl with an electric mixer until soft peaks form.
  4. Slowly pour the hot sugar syrup into the egg whites while beating on high speed. Continue beating until the meringue is glossy, stiff, and completely cooled.
  5. In a separate bowl, beat 2 cups (4 sticks, 454g) unsalted butter, softened, until light and fluffy.
  6. Gradually add the cooled meringue to the butter, beating on medium speed until completely combined and smooth. If the mixture curdles, continue beating; it will eventually come together.
  7. Add 1 teaspoon vanilla extract (or other flavoring) and beat until fully incorporated.
  8. Use immediately or store in an airtight container in the refrigerator (for up to 3 days) or freezer (for up to 3 months).
