Chocolate Swiss Meringue Buttercream is a creamy chocolate buttercream with silk finish. It’s a perfectly elegant frosting for cakes and cupcakes and less sweet than American buttercream. 


For the frosting

  • 5 large egg whites
  • 1 1/4 cups (237.5 g) granulated sugar
  • 1 1/2 cups (12 oz) unsalted butter, at room temperature
  • 2 teaspoons (10ml) vanilla extract
  • 6 ounces (226g) dark chocolate, melted


  1. For the frosting: Wipe down the inside of your stainless-steel bowl with vinegar to remove any grease. Combine sugar and egg whites in the bowl with candy thermometer attached.
  2. Set the bowl over top of a pot with 1 ¼ cups water covering the bottom. Place over medium heat.
  3. Stir constantly with a whisk until the mixture reaches 140°-160°  The sugar should be dissolved in the egg whites. You can test this by placing a drop on your finger tips and rubbing them together. The mixture should be completely smooth.
  4. In a microwave-safe bowl, microwave the chocolate 50% power in 30-second increments, stirring each time until the chocolate is melted and smooth. Set aside to cool.
  5. Immediately place the mixing bowl on your stand. Using the wire whisk attachment, beat the eggs white on low for 2 minutes than increase to medium high.
  6. Beat for another 5 minutes. At this point, your frosting should have turned white and the body of the meringue starts to form. Increase the mixing speed to high. It will start to look glossy as the peaks begin to form. Beat for another 5-8 minutes until the bottom of your bowl is cool to the touch and your meringue has stiff peaks.
  7. Turn your mixer down to medium-low. Slowly add your butter, 1 tbsp at a time. As you add more butter, the frosting might appear to have curdled and lost its body, that’s ok. Scrape down the sides of the bowl.
  8. Switch to the paddle attachment, add the vanilla extract and continue beating on medium-high speed until your frosting starts to form. Slowly drizzle in the chocolate and continue beating until stiff peaks form, about 3-5 minutes.
