There’s something truly magical about Seven-Minute Frosting — that glossy, cloud-like icing that once crowned every birthday cake and Sunday dessert. Light as air, sweet as a memory, and impossibly fluffy, this vintage frosting tastes like pure nostalgia.
If you grew up watching your grandmother whip it by hand over a pot of boiling water, you know exactly what I mean. Every bite is like a marshmallow dream — airy, silky, and shimmering white — with just a hint of vanilla to let the sweetness shine.
🕰️ Why It’s Called “Seven-Minute” Frosting
The name says it all: this frosting comes together in about seven minutes of constant beating over simmering water. The magic happens as egg whites, sugar, and water are gently heated, transforming into a glossy, stable meringue that’s as beautiful as it is delicious.
While it sometimes takes a few extra minutes depending on your heat and whisk speed, the results are worth every second — a smooth, satiny frosting that spreads like a dream and holds its shape perfectly on cakes and cupcakes.
🧂 Ingredients
- 2 large egg whites, unbeaten
- 1 ½ cups granulated sugar
- ⅓ cup cold water
- ¼ teaspoon cream of tartar (or 1 teaspoon corn syrup as a stabilizer)
- 1 teaspoon vanilla extract
🍰 Instructions
- Combine Ingredients
In the top of a double boiler (or a heatproof bowl set over simmering water), combine egg whites, sugar, water, and cream of tartar. Mix thoroughly until everything is well blended. - Beat Over Boiling Water
Place the bowl over the pot of boiling water (make sure the bottom doesn’t touch the water). Using a hand mixer, beat constantly on high speed. - Watch the Magic Happen
Continue beating for 7 to 10 minutes, until the frosting is thick, glossy, and holds stiff peaks. It should look like marshmallow fluff that can stand tall on its own. - Add Flavor
Remove from heat and beat in the vanilla extract until fully incorporated. - Frost Immediately
Use right away to frost cooled cakes or cupcakes. The frosting spreads beautifully and sets into a soft, glossy finish.
✨ Yield: Makes about 5 to 6 cups of frosting — enough for one 9-inch layer cake or about 24 cupcakes.
💡 Tips for Perfect Seven-Minute Frosting
- Use a clean, grease-free bowl. Any trace of fat will prevent the egg whites from whipping properly.
- Beat over simmering, not boiling, water. Too much heat can scramble the eggs instead of whipping them.
- Check for stiff peaks. The frosting should stand straight up when you lift the beaters.
- Frost immediately. Seven-minute frosting doesn’t store well — it’s best enjoyed fresh the day it’s made.
🎂 Ways to Use This Frosting
- Spread generously over a classic yellow layer cake or devil’s food cake.
- Use it as a topping for lemon or coconut cupcakes.
- Toast it lightly with a kitchen torch for a marshmallow-style finish.
- Swirl it over a chocolate sheet cake for that old-fashioned bakery look.
💭 Final Thoughts: A Sweet Taste of Simplicity
