White Mountain Frosting
Light, fluffy, and irresistibly glossy, White Mountain Frosting is a timeless classic that transforms any dessert into a showstopper. Made with just five staple ingredients—granulated sugar, water, egg whites, cream of tartar, and vanilla extract—this marshmallow-like frosting is as delicious as it is elegant. Its signature airy texture is achieved by carefully whipping soft peaks of egg whites and then slowly incorporating a hot sugar syrup, creating a glossy, cloud-like finish perfect for cakes, cupcakes, or layered desserts. The frosting’s sweet and subtly vanilla-infused flavor pairs beautifully with rich and buttery bakes, while the quick prep and cook time (just 25 minutes total!) make it a go-to for both novice and experienced bakers. Use this versatile frosting immediately for best results, and prepare to wow your taste buds with its melt-in-your-mouth perfection!

Ingredients
- 1.5 cups Granulated sugar
- 1.3 cups Water
- 3 large Egg whites
- 0.25 teaspoons Cream of tartar
- 1 teaspoons Vanilla extract
Directions
Step 1
In a medium saucepan, combine the granulated sugar and water, and stir gently to combine. Place over medium heat and let the mixture come to a boil without stirring further. Clip a candy thermometer to the side of the pan to monitor the temperature.
Step 2
Continue to boil the sugar syrup until it reaches 240°F (116°C), also known as the soft-ball stage. This typically takes 5–7 minutes. While waiting, move to the next step to begin preparing the egg whites.
Step 3
In a clean, dry mixing bowl, combine the egg whites and cream of tartar. Using a hand mixer or stand mixer fitted with the whisk attachment, beat the mixture on high speed until soft peaks form.
Step 4
Once the sugar syrup reaches 240°F, remove it from the heat immediately. With the mixer running on medium-low speed, very carefully and slowly drizzle the hot syrup into the beaten egg whites, pouring in a steady stream down the side of the mixing bowl to avoid splattering.
Step 5
Increase the mixer speed to high and beat the frosting until it is thick, glossy, and holds stiff peaks. This process will take about 7–10 minutes. The mixing will also help cool the frosting to room temperature.
Step 6
Add the vanilla extract and mix for an additional 30 seconds to incorporate.
Step 7
Use the frosting immediately to ensure it spreads easily and retains its fluffy texture. Spread onto cakes, cupcakes, or other desserts as desired. Note: Frosted desserts should ideally be consumed the same day or stored in a cool, dry place for up to one day.
