Make Ahead Swiss Meringue Buttercream Recipes

SWISS MERINGUE BUTTERCREAM

Steps:

• Wipe the bowl of an electric stand mixer and the whisk attachment with lemon juice to remove any trace of grease. Add sugar and egg whites to the bowl.
• Whisk sugar and egg whites together in the bowl of the stand mixer over simmering water, whisking constantly but gently, until temperature reaches 140 degrees F (60 degrees C), about 10 minutes. Return bowl to the stand mixer.
• Whisk sugar-egg white mixture in the stand mixer fitted with the whisk attachment until mixture is thick, glossy, and temperature of outside of bowl is room temperature. Change attachment to the paddle attachment and continue mixing on low speed. Add butter, 1 cube at a time; mix until silky-smooth. If mixture curdles, continue mixing and it will return to smooth.
• Pour vanilla extract and sprinkle salt into butter-sugar mixture; beat until fully incorporated.

SWISS MERINGUE BUTTERCREAM RECIPE

Steps:

• In a medium pot, add at least 1-inch of water and bring to simmer.
• Thoroughly wash and dry the stainless steel mixing bowl from your stand mixer (you don't want grease touching meringue). Add 7 egg whites and 2 cups sugar and whisk together. Place mixing bowl over a large saucepan of barely simmering water, creating a seal over the pot (bowl should be over the steam, not touching water). Whisk constantly until mixture reaches 160˚F (takes about 3 min). Sugar should be fully dissolved (you should not feel any sugar granules when rubbing mixture between finger tips). Mixture will feel hot to the touch.
• Wipe water from bottom of mixing bowl and transfer bowl to stand mixer fitted with whisk attachment. Beat on medium-high speed until stiff glossy peaks form (about 15-20 min) and bottom of the bowl feels completely at room temp and not warm (important: warm meringue will melt the butter).
• Once bowl is at room temp, switch to paddle attachment, reduce to medium speed and add butter 1 Tbsp at a time, adding it just as fast as it is absorbed by meringue. Once all butter is in, scrape down the bowl and continue beating until it reaches a thick whipped consistency (3 min on med-high speed). If it looks lumpy or liquidy at all, keep beating until smooth, thick and whipped.
• Add 2 tsp vanilla extract and 1/4 tsp salt and mix on med-high until incorporated (about 1 min).

FOOLPROOF SWISS MERINGUE

Steps:

• Bring 2 cups of water to a simmer in a medium pot.
• Combine sugar, egg whites, salt, and cream of tartar in the bowl of a stand mixer.
• Reduce the heat of the pot and place the bowl over the steam. Whisk egg whites lightly until a digital or candy thermometer inserted into the mixture reads 160 degrees F (71 degrees C), 6 to 10 minutes. Remove from heat immediately.
• Place bowl back onto the stand mixer with a whisk attachment. Whisk on high speed until egg whites are cool and stiff peaks form, about 3 minutes. Mixture should hold peaks effortlessly and start balling up around the whisk attachment while appearing silky, shiny, and pure white.
• Use meringue immediately. It will hold its shape without separating for about a week in the refrigerator.

• Place bowl on your stand mixer and whisk on med-high until the meringue is stiff and cooled (the bowl is no longer warm to the touch (approx. 5-10mins)).
• Switch to paddle attachment (optional). Slowly add cubed butter and mix until smooth.
• Add flavorings as desired whip until smooth.

• Reduce mixer to medium-low; add butter a scant 1/4 cup at a time, beating well after each addition. Mix in vanilla.
• Switch to paddle attachment; beat on lowest speed 3 to 5 minutes. Leave at room temperature if using same day.

SWISS MERINGUE BUTTERCREAM

Steps:

• Chose a medium saucepan and a medium heatproof bowl that you can use for your double boiler. You'll want to use a bowl that will neatly fit on top of your saucepan, but the bottom of the bowl CANNOT be touching the water below. (See photo below). Wipe down your bowl, making sure it's completely dry and there's no grease, residue, or crumbs left in it. Remove butter from the fridge and set aside. Carefully separate your egg whites.
• Add egg whites and sugar in your mixing bowl and whisk by hand to combine. Place bowl on top of a saucepan that's filled with a few inches of water and turn on medium heat.
• Continue to whisk by hand until your sugar has completely dissolved and your egg mixture has reached 70 C / 160 F. You can check this using a candy thermometer. The eggs will be thick and frothy. Remove from heat.
• Place eggs in the bowl of a stand mixer fitted with a whisk attachment. Whisk on medium speed until egg whites become thick and voluminous and reach stiff peaks. This can take around 10 minutes. The egg whites should hold their shape and not droop. The mixture should also be completely cooled.
• Turn your mixer down to low speed, then slowly add your butter, piece by piece. As you add your butter, your meringue mixture may turn soupy, and/or eventually look curdled - this is ok.
• Continue until you've added all your butter. Turn your mixer up to medium speed and continue to whisk until frosting comes together and is smooth again. Do not worry about over-mixing - keep going.
• Finally, add vanilla and salt. Mix briefly. Then remove bowl from mixer and use a spatula to give it one final stir by hand, getting rid of any air bubbles.
