Julia Child Bûche de Noël Recipe

Julia Child Bûche de Noël is the traditional French Christmas cake shaped like a Yule log. Julia’s recipe features an orange sponge cake made with almond flour, a light chocolate-meringue filling, and a rich ganache-like frosting textured to look like tree bark. Topped with meringue mushrooms, it’s the centerpiece of French holiday celebrations.

This is not a casual afternoon project. It has multiple components: Italian meringue, meringue mushrooms, chocolate filling, frosting, and an orange sponge cake. But each component is manageable, and you can make most of it ahead. The result is worth the effort.

I made this for Christmas dinner last year. When I set it on the table, nobody believed I baked it. That’s the reaction you want.

What is a Bûche de Noël? A soft sponge cake filled with buttercream, rolled into a log, covered in chocolate frosting textured like bark, and decorated with meringue mushrooms and powdered sugar “snow.”

How To Make Julia Child Bûche de Noël

Step 1: Make the Italian Meringue

1. Boil the sugar syrup: Combine sugar and ½ cup water in a saucepan. Bring to a boil, then cook without stirring until it reaches 238°F on a candy thermometer. Takes 4-5 minutes.
2. Beat the egg whites: While syrup cooks, beat whites with cream of tartar and salt until soft peaks form.
3. Add syrup to whites: With mixer on medium, slowly drizzle hot syrup into whites. Increase to high and beat until stiff peaks form and meringue is slightly warm, 5-7 minutes.

Step 2: Make the Meringue Mushrooms

4. Preheat oven to 200°F. Line a baking sheet with parchment.
5. Pipe mushroom shapes: Fill a pastry bag with meringue. Pipe 8-10 round kisses (¾ to 1¼ inch) for caps. Pipe 8-10 smaller cones for stems.
6. Smooth the caps: Dampen your finger and smooth any points to round them.
7. Bake 1 hour until dry to the touch. Cool completely on the pan.

Step 3: Make the Frosting and Filling

8. Melt chocolate: Set a bowl over simmering water. Add chocolate and hot coffee. Stir until melted and smooth.
9. Cool slightly: Let chocolate cool until warm to touch, about 15 minutes.
10. Make the frosting base: Transfer to stand mixer. Add Italian meringue, vanilla, and ¼ cup butter. Beat until smooth.
11. Divide the mixture: Transfer 2⅔ cups to a bowl for frosting. Cover and chill until firm and spreadable, about 1½ hours.
12. Make the filling: Add remaining ¼ cup butter to the chocolate left in the mixer (about ¾ cup). Beat until combined. Set aside.

Step 4: Make the Orange Sponge Cake

13. Preheat oven to 375°F. Butter and flour a 17½ x 12½ inch rimmed baking sheet. Line with parchment, butter and flour the parchment.
14. Grind almonds: Pulse almonds with 3 Tb sugar in food processor until finely ground.
15. Beat yolks: Beat egg yolks with ½ cup sugar on high until pale and thick, about 4 minutes.
16. Add flavorings: On low, beat in almond mixture, orange zest, orange juice, and almond extract.
17. Fold in flour: Sift flour over batter, fold in with spatula.
18. Beat whites to stiff peaks: In a clean bowl, beat egg whites on high. Gradually add remaining 3 Tb sugar, beat until stiff.
19. Fold whites into batter: Stir in about ¼ of the whites to lighten, then gently fold in the rest.
20. Bake 10-12 minutes until golden and cake springs back when pressed.
21. Immediately loosen edges. Dust top with 1½ Tb powdered sugar.
22. Roll the warm cake: Cover with parchment, then a damp towel. Invert. Remove top parchment. Dust with remaining powdered sugar. Roll from short side into a log, with parchment and towel. Wrap in plastic, chill 1 hour.

Step 5: Fill the Cake

23. Unroll carefully. Some small cracks are okay.
24. Spread filling evenly over the cake, leaving ½ inch border on all sides.
25. Re-roll without the towel and parchment. Roll tightly from short side.

Step 6: Assemble the Bûche

26. Trim the ends: Cut ½ inch from each end to even them.
27. Create the “knot”: Cut a diagonal 1-inch wedge from one end. Position flat side against the log to create a branch bump. Adhere with frosting.
28. Make the frosting: Mix chilled frosting with cocoa and 2 tsp orange juice or rum. Beat until smooth. Add more juice if needed.
29. Crumb coat first: Spread a very thin layer of frosting over the log. Leave the cut ends unfrosted.
30. Final frosting layer: Apply a thicker layer over the crumb coat.
31. Create bark texture: Drag fork tines across the frosting to make bark lines.
32. Attach mushrooms: Poke a hole in each cap base. Dab with frosting, insert stem. Arrange on the log.
33. Final touches: Dust mushroom caps with cocoa. Dust entire log with powdered sugar for “snow.” Add sugared cranberries and rosemary if desired.

Recipe Tips

• Work quickly with warm cake: The cake must be rolled while still warm and pliable. If it cools, it cracks.
• Spread frosting in one direction: Back and forth motion pulls up crumbs.
• The crumb coat matters: That thin first layer locks in crumbs so your final coat is clean.
• Mushrooms don’t need to be perfect: Real mushrooms have irregular shapes. Embrace it.
• Candy thermometer is essential: For the Italian meringue, you need the syrup at exactly 238°F.
• Don’t over-chill the cake: Slight cracks are normal. Over-chilling causes big cracks.

Make-Ahead

This recipe is designed for make-ahead. You can prepare Italian meringue, mushrooms, and chocolate-meringue filling up to two days in advance. Store mushrooms in an airtight container at room temperature. Let filling and frosting come to room temperature (2-3 hours) before using.

You can also bake and fill the cake one day ahead. Wrap the filled log in plastic, refrigerate. Store frosting separately. Frost and decorate on serving day.

The finished cake tastes best within two days. Store loosely covered in plastic in the refrigerator. Bring to room temperature one hour before serving.

How To Store

• Refrigerator: Loosely covered with plastic wrap, up to 2 days. Bring to room temperature for 1 hour before serving.
• Freezer: Not recommended. The meringue component doesn’t freeze well.
• Meringue mushrooms: Store unfilled in airtight container at room temperature, 1-2 days.
