This recipe is for a delicious and visually stunning dessert called Bûche de Noël, also known as Yule log. It is a traditional French dessert often served during the Christmas season. The Bûche de Noël resembles a log and is made with a light and airy roulade filled with a rich chocolate filling. The dessert is then decorated to look like a log, complete with meringue mushrooms and a chocolate icing that mimics the texture of tree bark.
Now, let’s break down the recipe into separate sections and present it in bullet point format:

FOR THE FILLING:
- 4 oz. semisweet chocolate
- 6 tbsp. sugar
- 3 egg yolks
- 12 tbsp. unsalted butter
INSTRUCTIONS:
FOR THE ICING:
- Melt chocolate and butter in the top of a double boiler set over simmering water.
- Whisk often until smooth.
- Remove from heat and gradually whisk in cream.
- Transfer to a medium bowl and set aside at room temperature, stirring occasionally, until icing thickens (about 4 hours).
FOR THE MERINGUE:
- Preheat oven to 200°F (93°C).
- Combine sugar and 1/4 cup water in a small saucepan and bring to a boil.
- Continue boiling until syrup reaches softball stage or 236°F (113°C) on a candy thermometer.
- In the bowl of a standing mixer, beat egg whites until frothy.
- Add cream of tartar and salt, and beat on high speed until soft peaks form.
- Gradually pour in sugar syrup while continuing to beat until whites cool to room temperature and become thick and shiny.
- Stir in vanilla.
- Transfer meringue to a pastry bag fitted with a 1/4″ plain pastry tip.
- Pipe meringue into mushroom shapes on a parchment paper-lined baking sheet.
- Bake meringues for 1 1/2 hours, then allow them to rest in the oven until dry and crisp.
- Assemble mushroom caps and stems using icing as “glue” and dust with cocoa powder.
FOR THE ROULADE:
- Preheat oven to 375°F (190°C).
- Line a baking pan with buttered parchment paper.
- Melt bittersweet chocolate in a mixing bowl and set aside.
- Bring cream to a boil, then pour over the chocolate and whisk until smooth.
- Beat egg whites until frothy, then gradually add sugar and beat until stiff peaks form.
- Mix one-third of the whites into the chocolate, then gently fold in the remaining whites.
- Spread the batter in the prepared pan and bake until a toothpick inserted in the center comes out clean.
- Set aside to cool in the pan.
FOR THE FILLING:
- Melt semisweet chocolate with water in a double boiler, then set aside to cool.
- Combine sugar and water in a saucepan and bring to a boil.
- Beat egg yolks until thick and pale yellow, then gradually pour in the hot syrup while beating.
- Beat until the mixture cools to room temperature.
- Soften butter and beat it into the egg mixture, one tablespoon at a time, until thick and smooth.
- Stir in the cooled chocolate and set aside.
TO ASSEMBLE THE BÛCHE:
- Transfer the cooled roulade to a work surface, sprinkle with rum, and spread the filling evenly over the top.
- Roll the roulade gently, peeling off the parchment paper as you roll.
- Cut diagonal stumps from the ends of the rolled roulade and set them aside.
- Carefully transfer the roulade to a serving platter lined with waxed paper.
- “Glue” the stumps onto the roulade with some of the icing.
- Melt a portion of icing and spoon it over the stumps to coat completely.
- Spread the remaining icing on the roulade, using a spatula to simulate tree bark.
- Remove the waxed paper strips and decorate with the meringue mushrooms.
- Sift confectioners’ sugar over the mushrooms and the Bûche de Noël.
