7 Minute Frosting is light, fluffy, and glossy—a marshmallow-like topping perfect for any cake. Easy, budget-friendly, and deliciously smooth!
Fill the bottom of a medium pot with a couple of inches of water and bring to a simmer.
Whisk together the egg whites, sugar, water, corn syrup, cream of tartar and the pinch of salt in a heat proof bowl and place on top of the simmering water.
Heat the mixture, whisking constantly, until it is hot and the sugar has melted (about 3 minutes). Rub a bit of the mixture between your thumb and index finger. It should be smooth and without any graininess. If not, continue heating and stirring for another minute and check again.
Transfer to the bowl of a stand mixer fitted with a whisk attachment (or use a large bowl and a handheld electric mixer) and whip on high for about 7 minutes, until stiff, glossy and cooled.
Add in the vanilla extract and whisk for one more minute to combine.
