Step-by-Step Instructions

Step 1: Prepare the pan and oven

Preheat the oven to 325°F (165°C) with a rack in the center. Butter a 9-inch (23 cm) springform pan, line the base with parchment, then butter the parchment and dust the sides with cocoa powder, tapping out any excess. This prevents sticking and adds a light cocoa edge to the torte.

Step 2: Melt the chocolate and butter

Place the chopped chocolate and butter in a heatproof bowl set over a pot of barely simmering water (do not let the bowl touch the water). Stir gently until melted and glossy. Alternatively, microwave on 50% power in 30-second bursts, stirring between each, until smooth. Set aside to cool for 5 minutes so it is warm, not hot.

Step 3: Purée the chestnuts with espresso

In a food processor, combine the roasted chestnuts, espresso (and rum/brandy if using), vanilla, and salt. Process for 1–2 minutes, scraping down as needed, until the mixture is very smooth and paste-like. If your processor struggles, add 1–2 teaspoons of hot water to help the blades catch.

Step 4: Build the batter

With the processor running, stream in the warm chocolate-butter mixture and process until blended. Add the egg yolks and 1/2 cup (100 g) of the sugar and process for 15–20 seconds more, until the batter looks thick and silky. Transfer this chestnut-chocolate base to a large mixing bowl.

Step 5: Whip the egg whites

In a clean bowl with clean beaters, beat the egg whites with the cream of tartar on medium speed until soft peaks form. Gradually add the remaining 1/4 cup (50 g) sugar while beating, then continue to medium peaks—glossy and holding a soft swoop at the tip.

Step 6: Fold and fill the pan

Whisk a big spoonful of the whites into the batter to loosen it. Switch to a large spatula and fold in the remaining whites in two additions, using broad, gentle strokes just until no large streaks remain. Scrape the batter into the prepared pan and smooth the top.

Step 7: Bake until just set

Bake for 35–40 minutes, until the edges are set, the top is slightly puffed and cracked, and the center still has a slight wobble. A skewer should emerge with moist crumbs, not wet batter. Do not overbake; the torte will firm as it cools.

Step 8: Cool, chill, and finish

Cool the torte in the pan on a rack for 1 hour. Run a thin knife around the edge, release the springform ring, and let cool completely. Cover and chill for at least 2 hours (or overnight) for clean slices. To serve, whisk the cream, powdered sugar, vanilla, and a pinch of salt to soft peaks. Spread or dollop over the torte and shower with shaved chocolate. A warm knife (dipped in hot water and wiped dry) makes neat slices.

Pro Tips

• Use vacuum-packed roasted chestnuts for ease and consistency; they purée smoother than freshly roasted chestnuts.
• For a satin-smooth base, purée the chestnuts fully before adding chocolate; add a teaspoon of hot water if the paste seems stiff.
• Keep temperatures friendly: let melted chocolate cool slightly and bring eggs to room temp to prevent seizing or curdling.
• Begin checking doneness at 32 minutes; a slight jiggle in the center keeps the texture truffle-like, not dry.
• Chill before slicing. This torte is easiest to portion when cold and tastes even more chocolatey on day two.

Variations

• Mocha–Orange: Add 1 tbsp orange liqueur and 1 tbsp finely grated orange zest to the batter. Garnish with candied orange peel.
• Boozy Almond: Swap rum for amaretto and top with toasted sliced almonds in addition to the shaved chocolate.
• From Fresh Chestnuts: Score 12 oz (340 g) raw chestnuts with an X, roast at 425°F (220°C) for 20–25 minutes, peel while warm, then proceed. Weigh to ensure about 12 oz peeled.

Storage & Make-Ahead

Refrigerate the uncovered torte until fully cold, then cover and keep up to 4 days. Add whipped cream and shaved chocolate just before serving. The baked torte (without topping) freezes well: wrap tightly and freeze up to 2 months; thaw overnight in the fridge. Batter is not recommended for make-ahead, but you can bake the torte a day in advance for best slicing and flavor.
