A professional-grade, silky-smooth Swiss Meringue Buttercream that is stable, glossy, and perfectly balanced in sweetness.

Ingredients

Scale
  • 5 Large Egg Whites
  • 300g Granulated Sugar
  • 450g Unsalted Butter (cubed and slightly softened)
  • 2 tsp Vanilla Extract
  • 1 pinch Fine Sea Salt

Instructions

  1. Set up a bain-marie by bringing an inch of water to a simmer in a saucepan.
  2. In a heat-proof glass bowl, whisk together the egg whites and granulated sugar.
  3. Place the bowl over the simmering water, ensuring the bottom does not touch the water. Whisk constantly until the sugar is dissolved and the mixture reaches 70°C.
  4. Transfer the mixture to a stand mixer fitted with a whisk attachment. Whip on high speed for 10 to 15 minutes until stiff, glossy peaks form and the bowl feels cool to the touch.
  5. Switch to a paddle attachment. With the mixer on medium-low, add the butter one cube at a time, allowing each to incorporate fully.
  6. Once all the butter is added and the frosting is smooth, add the vanilla and salt.
  7. Mix on low speed for 2 minutes to remove any large air bubbles.

Notes

  • Ensure all equipment is grease-free by wiping with lemon juice or vinegar.
  • If the mixture curdles when adding butter, just keep mixing; it will come together.
  • Butter should be cool-room temperature, not melted or too cold.
