Most marshmallow recipes start with gelatin packets and boiling-hot sugar syrup, but this marshmallow frosting is much easier. All you need to do is heat up sugar and egg whites until they’re just hot to the touch, then throw the mixture into the bowl of a stand mixer and whisk it into tall, billowy peaks. Try this fluffy vanilla-flavored topping sandwiched between chocolate graham crackers, or pile it on chocolate cupcakes and toast the peaks.
Game plan: To toast the marshmallow icing, you can use a small kitchen blowtorch. Alternatively, your cake or cupcakes can be toasted under the broiler.
