Chocolate Swiss Meringue Buttercream Recipes

Steps:

• Place the egg whites and sugar in a large metal mixer bowl set over simmering water. Whisk constantly until the sugar melts and the mixture is very thin and warm. Remove the bowl from the heat and whisk on high speed until stiff peaks form, about 5 minutes. Continue beating on low speed until cool.
• Beat in small pieces of cool but soft butter on medium speed. The mixture may curdle before coming together. Add the vanilla extract or other flavoring if using. (Re-beat occasionally while frosting a cake to maintain smooth texture.)

Steps:

• Place the egg whites and sugar in large metal mixer bowl set over simmering water. Whisk constantly until the sugar melts and the mixture is very thin and warm.
• Remove the bowl from the heat and whisk on high speed until stiff peaks form, about 5 minutes. Continue beating on low speed until cool, about 15 more minutes.
• Beat in small pieces of the cool but soft butter on low speed. The mixture may "curdle" before coming together. Add vanilla extract or other flavorings if desired. Rebeat occasionally while frosting the cake to maintain a smooth texture.

Steps:

• In the heatproof bowl of an electric mixer set over a saucepan of simmering water, combine the egg whites and sugar. Cook, whisking constantly, until sugar has dissolved and the mixture is warm to the touch (about 160 degrees).
• Attach bowl to the mixer fitted with the whisk attachment. Beat the egg-white mixture on high speed until it holds stiff (but not dry) peaks. Continue beating until the mixture is fluffy and cooled, about 15 minutes.
• Switch to the paddle attachment. With the mixer on medium-low speed, add the butter several tablespoons at a time, beating well after each addition. (If the frosting appears to separate after all the butter has been added, beat on medium-high speed until smooth again, 3 to 5 minutes more.) Beat in vanilla. Beat on lowest speed to eliminate any air bubbles, about 2 minutes. Stir with a rubber spatula until frosting is smooth.

Steps:

• Heat sugar and eggs Bring a saucepan filled with about 2 inches of water to a simmer. Meanwhile, combine sugar, egg whites, and salt in a large heatproof mixing bowl. Set bowl over (not in) simmering water, and whisk until whites are warm to the touch and sugar is dissolved, 2 to 3 minutes. (Heating the eggs relaxes their proteins, enabling the eggs to whip up higher and more quickly; the sugar also melts, for a silky smooth consistency.) Test by rubbing between your fingers; the mixture should feel smooth.
• Whip meringue Attach bowl to a standing electric mixer fitted with the whisk attachment, and beat on low speed until foamy. Add cream of tartar, and beat on medium-high speed until stiff, glossy peaks form and mixture is cooled completely, about 10 minutes.
• Mix in butter Reduce speed to medium-low; add butter 2 tablespoons at a time, beating to incorporate fully after each addition. Don't worry if the buttercream appears curdled at this point; it will become perfectly smooth again with continued beating. After all the butter has been incorporated, beat in vanilla.
• Finish Switch to the paddle attachment. Beat on the lowest speed to reduce air bubbles, 3 to 5 minutes. Let stand, covered with plastic wrap, at room temperature. (If not using the same day, transfer to airtight containers and store in the refrigerator up to 3 days or the freezer up to 1 month. Before using, bring to room temperature; beat with the paddle attachment on the lowest speed until smooth and pliable, about 10 minutes.)
• Follow recipe above, adding 5 1/2 ounces melted and completely cooled semisweet chocolate along with the vanilla.

Steps:

• In medium glass or metal bowl, beat egg whites and sugar with whisk until blended. Set over pan of simmering water, beating occasionally, until sugar has dissolved and egg mixture reaches 160°F on candy thermometer, 16 to 20 minutes. Remove from heat.
• Pour into bowl of electric stand mixer fitted with whisk attachment. Beat on high speed 2 to 3 minutes or until glossy peaks form and bowl has cooled to feel slightly warm. Still on high speed, slowly add 1 1/2 cups softened butter, one piece at a time, scraping side of bowl occasionally, until mixture is smooth, thick and shiny, 12 to 14 minutes. Beat in vanilla. If mixture separates, beat until smooth.
• In small microwavable bowl, microwave chopped chocolate uncovered on High 60 seconds, stirring halfway through microwave time. Continue to microwave in 10-second increments, until chocolate can be stirred smooth. Let stand 10 minutes. Beat cooled melted chocolate into frosting until smooth.
• Fill and frost 1 (8-inch) three-layer cake.

Steps:

• Whisk together sugar and egg whites in a heatproof mixing bowl. Place over a pot of simmering water; whisk constantly until sugar is completely dissolved, 2 to 3 minutes. Remove from heat. With an electric mixer, whisk on high speed until cool (test by touching bottom of bowl), 7 to 10 minutes.
• Change to the paddle attachment. With mixer on medium-high speed, add butter, 2 tablespoons at a time, until combined. Beat in chocolate.
