  • 1 1/2 cups heavy whipping cream
  • 4 large Safest Choice eggs room temperature
  • 2 tablespoons superfine sugar
  • 12 ounces dark chocolate use the best chocolate you can find
  • 1/4 cup unsalted butter chopped into small pieces


  • Whip the heavy whipping cream until it firmly holds peaks. Set aside in the refrigerator.
  • Whip the eggs and sugar until very fluffy and thick - this takes about 10 minutes on high speed in a stand mixer.
  • Melt the chocolate in a double boiler or in the microwave.
  • Mix the butter into the melted chocolate until it is all melted.
  • Add the chocolate/butter mixture a little bit at a time into the egg/sugar mixture, stirring well to fully incorporate the chocolate I do not suggest using an electric mixer for this as it is very easy to overmix using that method.
  • Fold in the whipped cream.
  • If you are serving right away, pipe onto cooled cupcakes and enjoy. Otherwise, cover and refrigerate the frosting. When ready to serve, whip the frosting for around 45 seconds at high speed to incorporate some air back into it. Then, pipe and serve. Alternatively, you could pipe onto cupcakes as soon as the frosting is done, refrigerate the frosted cupcakes, and bring the cupcakes back to room temperature before serving. I prefer to avoid refrigerating cupcakes when possible as I find that refrigeration changes their texture.


If you want to get fancy like I did, you can drizzle some melted chocolate on top of the mousse frosting. You won't regret that choice!
I adapted the mousse recipe from Ghirardelli's Chocolate Mousse Recipe.
