Ingredients:

  • 4 large eggs, separated
  • ¾ cup (150g) granulated sugar
  • ½ cup (60g) all-purpose flour, sifted
  • ¼ cup (30g) unsweetened cocoa powder, sifted
  • Pinch of salt
  • 2 tablespoons (30ml) whole milk
  • 1 teaspoon (5ml) vanilla extract
  • Powdered sugar, for dusting
  • 1 cup (240ml) heavy cream, cold
  • 8 ounces (225g) sweetened chestnut puree
  • 2 tablespoons (30ml) rum or brandy (optional)
  • 8 ounces (225g) semi-sweet chocolate, finely chopped
  • 1 cup (240ml) heavy cream
  • 2 tablespoons (30g) unsalted butter
  • 1 cup (120g) fresh cranberries
  • ½ cup (100g) granulated sugar
  • ½ cup (120ml) water
  • Additional granulated sugar, for coating

Instructions:

  1. Prepare the Jelly Roll Pan: Line the pan with parchment paper, leaving an overhang on the long sides for easy removal.
  2. Make the Sponge Cake Batter: Beat egg yolks with sugar until pale and thick. Whisk together flour, cocoa powder, and salt. Gently fold dry ingredients into the yolk mixture. Whisk egg whites until stiff peaks form. Gently fold egg whites into the batter in two additions. Stir in milk and vanilla extract.
  3. Bake the Sponge Cake: Spread batter evenly in the prepared pan. Bake until the cake springs back lightly when touched.
  4. Roll the Sponge Cake: Immediately invert the cake onto a clean kitchen towel dusted with powdered sugar. Peel off the parchment paper. Starting from one of the short ends, roll the cake up tightly in the towel. Let cool completely.
  5. Make the Chestnut Mousse Filling: Beat heavy cream until stiff peaks form. In a separate bowl, whisk chestnut puree with rum (if using). Gently fold whipped cream into the chestnut mixture.
  6. Assemble the Yule Log: Unroll the cooled cake. Spread the chestnut mousse evenly over the cake. Reroll the cake tightly, without the towel. Trim the ends of the log diagonally to create a more natural 'branch' look.
  7. Make the Chocolate Ganache: Heat heavy cream in a saucepan until simmering. Pour hot cream over chopped chocolate and let sit for a minute. Stir until smooth and glossy. Stir in butter. Chill ganache in the fridge for 30-40 minutes.
  8. Frost the Yule Log: Spread ganache evenly over the log, creating a rustic 'bark' texture with a fork. Attach trimmed ends to sides to resemble branches. Frost these as well.
  9. Make the Candied Cranberries: Combine sugar and water in a saucepan, and heat to dissolve. Add cranberries and simmer until softened and translucent. Remove cranberries and toss in granulated sugar to coat. Let dry on a wire rack.
  10. Garnish and Serve: Arrange candied cranberries on the log. Dust with powdered sugar. Chill before serving.
