This classic 7-minute frosting is named for how long it takes to make. You simply combine egg whites, sugar, water, and corn syrup and beat them over a double boiler. This melts the sugar and cooks the egg whites as you beat air into the mixture, making for a fluffy, almost marshmallow-like frosting.

If you don't have a double boiler, you can create a makeshift one using standard kitchen supplies. Pull out your saucepans and your heatproof mixing bowls. Find a bowl that sits snugly inside a saucepan, leaving space under the bowl so that it doesn't touch the boiling water. This will be your double boiler.

7-minute frosting is a delicious, dairy-free alternative to thick buttercream and tastes great on a variety of cakes. Try it on a rich chocolate cake for a nice contrast or keep everything light and airy with a coconut cake. This recipe makes enough to frost two layers.

  3. Beat the mixture off of the heat with an electric hand mixer for a minute. Place the pan over the boiling water (make sure the bottom of the pan is not touching the boiling water).

  4. Continue beating for about 6 minutes, or until the frosting mixture is white, fluffy, and will stand in stiff peaks.

  5. Remove from the heat and beat in the vanilla. Use immediately to frost a two-layer cake or cupcakes.

Tips

  • You'll want to use a hand mixer to make this frosting. Since it needs to cook as it's being mixed, a stand mixer won't do and whisking by hand will take ages.
  • Be prepared to stand in front of the stove and beat the mixture for the full 6 minutes. You can't walk away in the middle or you'll risk curdling the eggs.
  • This deliciously fluffy frosting has a short lifespan. It's best eaten within a few hours of it being made, but will last a couple of days. After the first several hours, it tends to form some sugar crystals, losing some of its creaminess.
  • To save time, make the cake ahead of time so that it is completely cool. Whip up fresh frosting within a few hours of serving.

Recipe Variations

  • Swap the light corn syrup for dark corn syrup or maple syrup for a slightly different flavor.
  • Replace the vanilla extract with a different flavor extract, such as almond or lemon.
