Quick Baking Tips & Fun Fact
Fun Fact
Swiss Meringue Buttercream gets its signature light, silky texture because the sugar and egg whites are gently heated together before whipping. This completely dissolves the sugar crystals, giving you a cloud-like frosting that is far less sweet than traditional American buttercream.
Key Baking Tips
Simple 1:1 Brown Sugar Swap: Since granulated sugar and dark brown sugar swap equally 1:1 by weight, you can use 10.8 oz of granulated sugar for a classic, bright white vanilla frosting, or swap in 10.8 oz of dark brown sugar for a warm, caramel-like variation.
No More Grainy Meringue: Pinch a bit of the warm egg white and sugar mixture between your fingers before taking it off the heat. If it feels completely smooth with no sugar grains left, it is ready to whip.
Temperature Matters: Ensure your whipped meringue bowl cools down until it feels neutral or barely warm to the touch before adding the butter. If the meringue is too hot, the butter melts; if it's too cold, the butter can curdle (if that happens, just keep whipping!).
Ingredients
Egg Whites: 5.4 oz
Granulated Sugar: 10.8 oz (For Brown Sugar SMBC, swap 1:1 with 10.8 oz Dark Brown Sugar)
Unsalted Butter (Room Temp): 1 lb (16 oz)
Salt: 1 tsp
Vanilla Extract: 2 tsp
Equipment & Supplies Used
Step-by-Step Instructions
Dissolve Sugar & Egg Whites: Combine the egg whites and granulated sugar (or dark brown sugar) in a heatproof mixer bowl. Set the bowl over a pot of simmering water (double boiler), ensuring the bottom of the bowl does not touch the water. Whisk constantly until the sugar is completely dissolved and the mixture reaches 125°F - 130°F.
Whip the Meringue: Transfer the bowl to your stand mixer fitted with the whisk attachment. Whip on high speed for 15–20 minutes until stiff, glossy peaks form and the bottom of the bowl feels cool to the touch.
Add Butter: Switch to the paddle attachment. With the mixer running on medium speed, add the room-temperature butter 1–2 tablespoons at a time, letting each piece incorporate before adding the next.
Season & Smooth: Add the salt and vanilla extract. Continue whipping until the frosting comes together into a smooth, silky buttercream. Turn the mixer to low speed for 2–3 minutes to knock out any large air bubbles before piping or spreading.
Key Baker Tips
For Cupcakes: Swirls onto 24 to 30 cupcakes (or up to 36 with a lighter piping technique).
For Layer Cakes: Frosts and fills a two-layer 8-inch cake (or fills and lightly coats a three-layer 8-inch cake).
For Sandwich Cookies: Fills roughly 30 to 36 sandwich cookies (or around 15–18 large, generously filled gingerbread men).
For Macarons: Pipes the filling for about 60 to 75 macaron shells (30–37 assembled macarons).
