Makes 1 bûche de Noël
Ingredients
  • 4 large eggs (200 grams), room temperature
  • ¾ cup (150 grams) granulated sugar
  • 1 teaspoon (6 grams) vanilla bean paste
  • ¾ cup (94 grams) all-purpose flour
  • ⅓ cup (25 grams) Dutch process cocoa powder, plus more for dusting
  • 1 teaspoon (5 grams) baking powder
  • ½ teaspoon (1.5 grams) kosher salt
  • ¼ cup plus 2 tablespoons sour cream (90 grams), room temperature
  • ¼ cup (56 grams) vegetable oil
  • Cold Brew Simple Syrup (recipe follows)
  • Vanilla Bean Buttercream (recipe follows)
  • Chocolate Buttercream (recipe follows)
  • Meringue Mushrooms (recipe follows)
  • Garnish: ground pistachios, confectioners’ sugar
Instructions
  1. Preheat oven to 350°F (180°C). Spray a 17½x12½ rimmed baking sheet with baking spray with flour. Line pan with parchment paper; spray parchment.
  2. In the bowl of a stand mixer fitted with the whisk attachment, beat eggs and granulated sugar at high speed until thick and pale, 5 to 7 minutes. Beat in vanilla bean paste.
  3. In a medium bowl, sift together flour, cocoa, baking powder, and salt. Gently fold flour mixture into egg mixture.
  4. In a small bowl, whisk together sour cream and oil. Fold sour cream mixture into egg mixture, scraping bottom of bowl to fully combine. Spread batter into prepared pan, smoothing top with an offset spatula.
  5. Heavily dust a tea towel with cocoa.
  6. Bake until set and top springs back when touched, 10 to 12 minutes. Immediately run a sharp knife around edges of pan to loosen cake. Turn out cake onto prepared tea towel. Gently peel off parchment. Trim edges, if desired. Starting with one long side, roll up cake and towel together. Let cool completely on a wire rack.
  7. Carefully unroll cake, and brush with Cold Brew Simple Syrup. Spread Vanilla Bean Buttercream on top. Reroll cake without towel, and place, seam side down, on a baking sheet, using towel as a sling. Cover with towel, and refrigerate until firm, about 1 hour.
  8. Trim ends of cake flat. Trim 3 to 4 inches diagonally from one end; set aside. Trim a ¾-inch slice from same end; set aside.
  9. Place large cut piece at an angle off side of cake, and attach with Chocolate Buttercream. Place small cut piece, angle cut side up, on top, and attach with Chocolate Buttercream. Spread remaining Chocolate Buttercream on outside of cake. Use an offset spatula to create detailed bark ridges. Decorate with Meringue Mushrooms; garnish with pistachios and confectioners’ sugar, if desired.

Meringue Mushrooms
 
Makes about 24 mushrooms
Ingredients
  • 2 large egg whites (60 grams)
  • ¼ teaspoon cream of tartar
  • ⅛ teaspoon kosher salt
  • ½ cup (100 grams) granulated sugar
  • ¼ cup (40 grams) dark chocolate melting wafers, melted according to package directions and cooled slightly
  • Cocoa powder, for dusting
Instructions
  1. Preheat oven to 275°F (140°C). Line a rimmed baking sheet with parchment paper.
  2. In the bowl of a stand mixer fitted with the whisk attachment, beat egg whites, cream of tartar, and salt at low speed until foamy. With mixer on high speed, add sugar in a slow, steady stream. Beat until stiff peaks form.
  3. Place meringue in a large piping bag fitted with a ½-inch round tip. Holding tip perpendicular to parchment paper, pipe half of meringue as mushroom tops, ¾ to 1¼ inches across. (Use a wet finger to press down any points.) With remaining meringue, pipe stems as large kisses with ½-inch wide base. (It is OK if the kisses don’t have smooth tips.)
  4. Bake until meringues look dry and have started to brown slightly, 30 to 40 minutes. Let cool completely.
  5. Using a wooden pick, poke a small hole in bottom of each mushroom top. Dip or brush melted chocolate on bottom of each mushroom top, and insert pointed stem end. Let stand until chocolate is set, about 5 minutes. Lightly dust with cocoa before serving. Best served the same day.
