Recipe Information
Ingredients
- 1 cup Granulated sugar
- 4 large Egg whites
- 0.25 teaspoon Cream of tartar
- 0.25 cup Water
- 1 teaspoon Vanilla extract
Instructions
In a clean and heatproof bowl, combine granulated sugar, egg whites, cream of tartar, and water.
Place the bowl over a pot of simmering water, ensuring that the bottom of the bowl does not touch the water. Whisk continuously until the sugar dissolves and the mixture reaches 160°F (70°C) on a candy thermometer. This process will take about 5-7 minutes.
Transfer the bowl to a stand mixer fitted with a whisk attachment (or use a hand mixer). Beat the mixture on high speed for 6-8 minutes, or until stiff, glossy peaks form and the mixture has cooled to room temperature.
Add vanilla extract and beat for an additional 30 seconds to incorporate.
Use immediately to frost cakes, cupcakes, or cookies. The frosting is best used the same day but can be stored in an airtight container at room temperature for up to 6 hours.
