Snowy white, light and fluffy. This frosting tastes like marshmallow cream and melts in your mouth with every bite.
Seven-Minute Frosting (also known as divinity frosting or boiled icing) is an old American recipe, dating back to at least the 1900s. It results in signature glossy, fluffy swirls. The “seven-minute” in the name refers to the time needed to beat the frosting, although it may take slightly longer. Like many older recipes, there are many versions of this frosting - with variation in the ingredients, cooking times and temperatures - as baking used to be more about intuition than method.
This frosting is made of simple ingredients and is quick to make, but preparation and attention to detail are key. When making this recipe, keep the factors detailed below in mind to ensure success. The ingredients are cooked over a water bath and then whipped into a glossy meringue. The corn syrup reduces the chance of a grainy frosting, and the cream of tartar helps stabilize the egg whites. The addition of water and the lack of butter distinguishes this frosting from a Swiss meringue buttercream. Without any butter, Seven-Minute Frosting is fat-free.
