Instructions

Prepare the syrup

In a small saucepan over medium heat, combine granulated sugar and water. Stir until the sugar dissolves, then stop stirring and let it come to a boil.

Pro tip: Use a wet pastry brush to wipe down any sugar crystals on the sides of the pan.

Heat the syrup

Attach a candy thermometer to the pan and heat the syrup until it reaches 115°C (240°F).

Pro tip: Ensure the thermometer does not touch the bottom of the pan for an accurate reading.

Beat the egg whites

While the syrup is heating, beat the egg whites and cream of tartar in a large bowl until soft peaks form.

Combine syrup and egg whites

With the mixer running on low, slowly pour the hot syrup into the egg whites.

Pro tip: Pour the syrup in a thin stream to prevent cooking the egg whites.

Increase speed

Increase the mixer speed to high and beat until the frosting forms stiff, glossy peaks, about 5-7 minutes.

Pro tip: The bowl should feel cool to the touch when the frosting is ready.

Add vanilla

Beat in the vanilla extract until just combined.
