Instructions

  1. Step 1: Place 6 oz semi-sweet chocolate chips in a heatproof bowl. Pour 1/4 cup hot brewed espresso over the chocolate and let sit for 1 minute, then stir until smooth and glossy. Let cool to room temperature.
  2. Step 2: In a chilled mixing bowl, whip 1 1/2 cups cold heavy cream with 1 tsp vanilla extract until soft peaks form. Set aside.
  3. Step 3: In a separate clean bowl, beat 2 large egg whites with 2 tbsp granulated sugar and 1 pinch of salt until stiff, glossy peaks form.
  4. Step 4: Gently fold the cooled chocolate-espresso mixture into the whipped cream until combined. Then carefully fold in the beaten egg whites in 2 additions until no streaks remain.
  5. Step 5: Spoon the mousse evenly into 6 small serving cups. Refrigerate at least 2 hours to set.
  6. Step 6: Before serving, garnish each cup with dark chocolate shavings.

How do I store leftover No-Bake Chocolate Espresso Mousse Cups?

Cool fully before storing. Most baked desserts keep at room temperature in an airtight container for 2–3 days, or in the fridge for up to 5 days. Cream- or custard-based desserts must go in the fridge within 2 hours; reheat gently or serve cold per the recipe.

Can I substitute ingredients in No-Bake Chocolate Espresso Mousse Cups?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut).

How do I scale No-Bake Chocolate Espresso Mousse Cups for a different number of people?

The recipe is written for 6 servings. Multiply each ingredient by (your serving target / 6). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
