Total Time: 1 hour, 15 minutes
- Genoise cake batter:
- 4 eggs (room temperature)
- 2/3 cup sugar
- 1 tablespoon Grand Marnier (orange liqueur)
- 2 teaspoons orange zest
- 3/4 teaspoon vanilla extract
- 1/4 teaspoon salt
- 1 cup cake flour
- Chocolate buttercream:
- 7 egg whites
- 1 1/3 cups granulated sugar
- 6 ounces unsweetened chocolate, melted and cooled
- 1 teaspoon instant espresso powder
- 1/2 teaspoon vanilla extract
- 3 cups plus 3 tablespoons butter, softened
How to make buche de Noel:
Preheat the oven to 400 degrees. Butter a 10-inch by 15-inch baking pan with a 1-inch lip (jelly-roll pan) and line it with parchment paper. Butter the parchment or spray it with cooking spray. Set the pan aside.
Beat the eggs for 5 minutes, until they turn thick and foamy. Add the sugar, orange liqueur, orange zest, vanilla extract, and salt to the eggs and continue beating for 2 minutes. Fold the flour, a few tablespoons at a time, into the whipped egg mixture. Once the flour is incorporated into the batter, stop mixing. Do not overmix or the cake will bake up into a tough texture.
Gently spread the batter into the prepared pan. There will be peaks of batter; gently smooth over them, but do not press the batter down. Bake the cake for 10 minutes, until the cake is just set. Invert the baked cake onto a clean, dry kitchen towel and peel off the parchment paper. Wait 3 minutes and then gently roll the cake, still in the towel, starting at the 10-inch end. Allow it to cool completely.
To make the chocolate buttercream:
In a clean, completely dry bowl beat the egg whites on high until soft peaks form. Set them aside for a moment.
In a small saucepan, bring the sugar and 2/3 cup water to a boil. Allow it boil until it has reduced into a slightly thickened syrup. Begin beating the egg whites on high speed again, and pour the hot sugar syrup into the eggs in a slow, steady stream. Pour the melted chocolate, espresso powder, and vanilla extract into the egg whites and continue beating them until the meringue has cooled completely, about 5 minutes.
Add the softened butter to the meringue, 2 tablespoons at a time, while beating on high speed, until all of the butter is incorporated into the frosting. If the buttercream becomes runny at any time in this process, refrigerate the meringue until it has chilled through and continue the process of beating the butter into the meringue.
To assemble the buche de noel:
Unroll the cake and set aside the towel. Evenly spread 2 cups (or desired amount) of the chocolate buttercream on the inside of the cake and following its natural curve, gently form it into a cake roll. Cut off the ends of the cake roll on the diagonal and reattach them in the center of the cake with a bit of buttercream to fashion a “branch” coming off the main Yule log.
Spread the exterior of the buche de noel with enough chocolate buttercream to cover it and gently pull a butter knife or small, offset spatula through the frosting to give the appearance of rough tree bark. Add a Pere Noel figure and meringue mushrooms to complete the festive look.
Chill the cake before serving it, and refrigerate any leftovers.
