Swiss Meringue Buttercream Recipe
This Swiss Meringue Buttercream frosting pairs beautifully with our Buttermilk-Chocolate Cake, but it would be delicious with almost any layer cake—it’s incredibly light and fluffy and doesn’t weigh down delicate cake layers. When making the frosting, add the butter slowly and don’t rush this step. It takes about 15 minutes to incorporate all of it. As you add the butter, the frosting may appear broken at some point, but it will come back together. Best of all, you can make it in advance; it’s surprisingly stable and will hold in the refrigerator for several days.
