Instructions

  1. Step 1: Place 6 oz chopped dark chocolate in a heatproof bowl over a pot of simmering water (double boiler) and stir until melted and smooth. Remove from heat and let cool slightly.
  2. Step 2: In a large bowl, whip 1 1/2 cups heavy cream with 2 tbsp granulated sugar and 1 tsp vanilla extract on medium-high speed until soft peaks form.
  3. Step 3: Gently fold one-third of the whipped cream into the melted chocolate until combined, then fold in the remaining whipped cream carefully to maintain airiness.
  4. Step 4: In serving glasses, layer 1/4 cup crushed ladyfinger biscuits, followed by 1/3 of the chocolate mousse. Repeat layering twice more, ending with mousse on top.
  5. Step 5: Dust the top of each parfait with 1 tbsp unsweetened cocoa powder using a fine sieve. Chill in the refrigerator for at least 2 hours before serving.

Frequently asked questions

How long does Layered Equation Chocolate Mousse Parfait take to make?

Total time is about 20 minutes (20 min prep + 0 min cook). Most home bakers find this fits a weekend afternoon; chill or store as the recipe directs before serving.

How do I store leftover Layered Equation Chocolate Mousse Parfait?

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 Layered Equation Chocolate Mousse Parfait?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Layered Equation Chocolate Mousse Parfait for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). 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.
