Meringue Buttercream Double Batch

The smoothest, most buttery and delicious frosting you’ll ever make.

This luscious buttercream is made with a Swiss meringue technique. Swiss meringues, different than Italian meringues, mixes the sugar and egg whites together over heat, dissolving the sugar, then whipping it into a fluffy meringue. Add softened butter a little at a time and you end with the most dreamy, melt-in-your mouth frosting you can imagine.

Here I’ve included a double batch recipe. My single batch, here, is just the same but makes about 5 cups instead of ten! You’ll need ten cups for my Party Rainbow Cake and other large creations.

This is a double batch of my not-too-sweet buttercream. It is a great alternative to frosting made with confectioners' sugar.

Calories: 1719 kcal

Ingredients

• 10 large egg whites
• 2 ½ cups sugar
• 8 sticks (4 cups) unsalted butter at room temperature
• 2 tsp vanilla extract

Instructions

1. Whisk together egg whites and sugar in a heatproof mixing bowl over a pan of simmering water until sugar has dissolved, about 5 min. Test by rubbing the mixture between your fingers - you shouldn't feel any sugar crystals.
2. Transfer bowl to the mixer with a whisk attachment or use a handheld mixer and beat on high until it cools and stiff peaks form, 10 to 12 min.
3. Reduce speed to medium-high and add butter a few tablespoons at a time. (Buttercream may curdle but will become smooth as you continue to beat it.) Add Vanilla
4. Use within a few hours or refrigerate for u to a week. Buttercream can be frozen for up to a month. Before using, bring to room temperature and beat on low until smooth.

Recipe Notes

This is a double batch of meringue buttercream that is needed for larger projects like Party Rainbow Cake.
