Seven-Minute Frosting is made from combining egg whites and sugar over a double-broiler until it becomes light and fluffy to decorate a cake. This icing is made by stirring the mixture over a pot of simmering water or double broiler on top of the stove for about seven minutes until it transforms into a smooth, velvety texture.
This frosting is perfect on classic vintage cakes like my Lady Baltimore Cake and Lord Baltimore Cake.

Ingredients to make 7-minute Frosting
- Superfine sugar, also known as castor sugar, has a finer texture compared to granulated sugar. Its fine granules help yield tender baked goods by incorporating quickly with other ingredients. When making boiled frostings or candy, superfine sugar dissolves faster, reducing grittiness and creating a smoother texture.
- Vanilla provides warm notes of caramel and spice, enhancing the depth of flavor in baked goods. Choose a pure, all-natural extract made from real vanilla beans with at least 35% alcohol.
- Eggs are produced by chickens and provide structure and stability in baking, while their proteins trap air, creating natural leavening.
- Cream of Tartar is an acidic salt that forms inside wine barrels that is commonly used in baking to stabilize egg whites and prevent sugar syrups from crystallizing.
- Pink salt is a type of rock salt found near the Himalayas, that is minimally processed and contains trace minerals.
Make your own ingredients
Vanilla: Purchase Grade B vanilla beans (also called extract-grade), which have less moisture and a more concentrated flavor. Place 8 oz. of bourbon (or vodka) in glass bottle or jar. Split 5 – 7 vanilla beans down the middle and add to bottle. Store in a cool, dark place for 3 – 6 months before using. It will keep for many years, so as you use it, just top off with more bourbon and more beans.

Finish the look with a simple garnish of fruit or nuts to complement the flavor profile.
