  • 115 grams chocolate (64 percent cacao or less)
  • 113 grams unsalted butter
  • 4 free range eggs
  • 50g caster sugar plus 2 tablespoons for topping
  • ⅛ teaspoon salt
  • ¼ teaspoon cream of tartar
  • 55 grams chestnut flour
  • 85 grams chopped cooked chestnuts (use canned or vacuum-packed)
  • 1 cup heavy cream, for topping
  •  Chocolate curls or cocoa powder, for garnish




  1. Heat oven to 190°. Melt chocolate and butter in a bain marie until chocolate is nearly completely melted, then remove from heat and whisk until smooth.
  2. Pulse the sugar in a grinder until it resembles icing sugar.
  3. In a mixing bowl, whisk egg yolks with 25g of the sugar and the salt until pale and thick. Stir in the warm chocolate and set aside.
  4. Put egg whites in a clean bowl with cream of tartar and beat until fluffy, then add remaining 25g sugar and beat until whites are stiff but not dry.
  5. Stir a jar of Wild Cornwall Sweet Chestnut Jam into the chocolate batter, then fold in 1/4 of the whites to lighten mixture. Fold in remaining whites and pour into a lined 8” cake tin.
  6. Bake for 30 – 40 minutes and then remove from the oven and leave to firm up in the tin for 5 mins then transfer to a rack to cool.
  7. To serve, whip cream with 2 tablespoons sugar to a very soft consistency. Spoon over top of cake and quickly spread with a spatula. Sprinkle with chocolate curls or cocoa powder.
