- 2 tbsp (15 g) powdered sugar
- 1/2 tsp pure vanilla extract

- 1/4 cup (60 ml) water
- 3 tbsp (45 ml) cognac (or brandy)
- 1/2 tsp pure vanilla extract
- Pinch fine sea salt
- Optional: 1 strip orange peel (about 1 x 3 inches)
For Assembly
- 3 oz (85 g) dark chocolate, 60–70% cacao, shaved into curls

- Fresh mint leaves or candied chestnut pieces (optional garnish)
Step-by-Step Instructions
Step 1: Chill tools and shave the chocolate
Place a large mixing bowl and beaters (or whisk attachment) in the refrigerator for 10 minutes to ensure the cream whips quickly. Using a vegetable peeler, shave the long side of the chocolate bar to create curls. Refrigerate the shavings so they stay firm.
Step 2: Make the cognac syrup
In a small saucepan, combine the sugar, water, and a pinch of salt. Add the orange peel if using. Bring to a simmer over medium heat, swirling occasionally, until the syrup thickens slightly and reaches 225°F (107°C), about 4–6 minutes. Remove from the heat; discard the peel. Stir in the cognac and vanilla. Transfer to a small jar and cool until pourable but syrupy, 20–30 minutes. If it thickens too much as it cools, loosen with 1–2 tsp warm water.
Step 3: Whip the cream for the mousse
Pour 1 1/2 cups cold heavy cream into the chilled bowl. Whip to soft peaks (the tip gently folds over), 2–3 minutes with a mixer on medium. Do not overwhip. Refrigerate while you prepare the chestnut base.
Step 4: Prepare the chestnut base (add gelatin if using)
In a separate bowl, beat the chestnut spread, mascarpone, vanilla, and salt until smooth and glossy, about 1 minute. If using the stabilizer, sprinkle gelatin over 1 tbsp cold water and let bloom for 5 minutes. Warm 2 tbsp cream or milk just to steaming, then whisk in the bloomed gelatin until fully dissolved. With the mixer on low, slowly stream the warm gelatin mixture into the chestnut base until combined.
Step 5: Fold into a silky mousse
Using a spatula, fold the whipped cream into the chestnut base in two additions, turning the bowl and lifting the mixture to keep it airy. Stop as soon as no streaks remain. Taste and adjust salt or vanilla if desired. The mousse should be light and spoonable.
Step 6: Whip the vanilla cream for layering
In a clean chilled bowl, whip 1 cup heavy cream with powdered sugar and vanilla to soft peaks, 1–2 minutes. This will be your bright, lightly sweetened contrast to the chestnut mousse.
Step 7: Assemble and chill
Spoon 3–4 tbsp chestnut mousse into the bottom of each glass, followed by 2 tbsp vanilla whipped cream and a pinch of chocolate shavings. Repeat the layers once more, finishing with a swoop of whipped cream and extra chocolate on top. Cover and refrigerate until nicely chilled and lightly set, at least 2 hours and up to 24 hours. Just before serving, drizzle 1–2 tsp cognac syrup over each parfait and garnish with mint or a piece of candied chestnut.
Pro Tips
- For distinct layers, use the optional gelatin or chill the mousse 15–20 minutes before layering.
- Shave chocolate from a room-temperature bar for the best curls; then chill the curls to keep them crisp.
- Whip to soft peaks only. Overwhipped cream can turn grainy and won’t fold smoothly.
- For a stronger cognac note, drizzle at the table rather than mixing alcohol into the mousse.
- Unsweetened chestnut purée works too—sweeten the mousse base with 1/4–1/3 cup (50–65 g) sugar to taste.
Variations
- Kid-friendly: Replace cognac syrup with maple-vanilla syrup (1/2 cup maple syrup + 1/2 tsp vanilla; warm gently and cool).
- Mocha twist: Add 1 tsp instant espresso powder to the chestnut base and use espresso-infused dark chocolate.
- Orange-cardamom: Infuse the syrup with both orange peel and 2 lightly crushed cardamom pods; garnish with fine orange zest.
Storage & Make-Ahead
Parfaits keep well, covered and refrigerated, for up to 2 days. Add the cognac syrup and fresh garnish just before serving for the best look. The cognac syrup can be made up to 2 weeks ahead and refrigerated; bring to room temperature to loosen. Chocolate shavings can be made 1 day ahead and stored chilled in an airtight container.
