Swiss Chocolate Buttercream Ingredients

765 g bittersweet chocolate, finely chopped

170 g pasteurized egg whites; room temperature

339g granulated sugar

Pinch cream of tartar

¾ tsp. salt

681 g unsalted butter; softened (but not melted)

21 g vanilla bean paste

Method

Melt the chocolate over simmering water, remove from heat and set aside.

Warm the egg whites, cream of tartar, sugar, and salt in the bowl from the Kitchen Aid mixer over barely simmering water until they reach 100 degrees, about 5 minutes of constant stirring. Put the bowl on the mixer and whip on high speed until the meringue is cool and holds a stiff peak. Add the butter, 1 tablespoon at a time, while beating on medium speed. Scrape down the bowl, add the chocolate and vanilla, mix for 1 minute or until the chocolate is completely blended in. If the butter cream seems soft, refrigerate for 5-15 minutes while giving it an occasional stir.

Place in piping bag and pipe onto cooled cupcakes.
