I looked at a handful of recipes – and each were so different! I chose one simple recipe from Food.com I had all the ingredients for and adapted it.
8 ounces semisweet chocolate
3 tablespoons powdered sugar
3 tablespoons strong brewed coffee
2 tablespoons butter
2 egg yolks
1/4 tsp. rum extract
1-1/4 cups whipping cream
Melt chocolate in a double broiler or in a bowl above a pan of simmering water.
Add sugar, coffee, butter and egg yolks, one at a time. Stir until mixture has thickened. Remove from heat and let cool.
Whip cream to stiff peaks. Add to cooled mixture in thirds.
Spoon mousse into individual serving dishes. Cover. Let set in refrigerator 1 hour.
Garnish with a dollop of whipped cream.
Happy National Chocolate Mousse Day!
