Yule Log Cake (Bûche de Noël)

Ingredients

Ingredient notes & substitutions

Eggs:

Separating them is key — whipped yolks give richness and whipped whites give the sponge its light, flexible structure so it rolls without cracking.

Cocoa powder:

Used in both the sponge and the buttercream for deep chocolate flavor. Sift it well to avoid lumps in the delicate batter.

Heavy cream:

Cold cream whips into the airy filling and also loosens the buttercream. Keep it well chilled for the best whip.

Powdered sugar:

It sweetens the filling and buttercream, and a generous dusting at the end creates the signature snowy, forest-log look.

Butter:

Softened butter makes the buttercream smooth and spreadable — the base for those realistic fork-dragged bark ridges.

Method

1. 1

   Preheat the oven to 350°F (175°C) and line a 10x15-inch jelly roll pan with parchment paper.

2. 2

   Beat the egg yolks with half the granulated sugar until pale, thick, and doubled in volume, then beat in the vanilla.

   
3. 3

   Sift the flour, cocoa, and salt over the yolks and gently fold in.

4. 4

   In a clean bowl, whip the egg whites to soft peaks, gradually adding the remaining sugar, until stiff and glossy. Fold into the batter in thirds.

   
5. 5

   Spread the batter evenly in the pan and bake for 10 to 12 minutes, until the top springs back when lightly touched.

   
6. 6

   Turn the warm cake out onto a clean towel dusted with powdered sugar, peel off the parchment, and roll it up with the towel from the short end. Let it cool completely, rolled.

   
7. 7

   Whip the cold cream with the powdered sugar and vanilla to stiff peaks. Gently unroll the cake, spread with the whipped cream, and re-roll (without the towel).

   
8. 8

   Make the buttercream: beat the butter, powdered sugar, cocoa, and cream until fluffy and spreadable. Frost the log all over, then drag a fork lengthwise to create bark-like ridges.

   
9. 9

   Dust with powdered sugar for a snowy finish, decorate if you like, and chill until ready to slice.

   

Variations to try

• Add 1 teaspoon of espresso powder to the buttercream for a mocha yule log.
• Brush the sponge with a little coffee or orange liqueur before filling for extra flavor.
• Fold crushed peppermint or chopped chestnuts into the whipped cream filling.
• Add meringue mushrooms, fresh rosemary 'pine,' and cranberry 'berries' for a woodland scene.

Storage & make-ahead

Store the assembled cake, loosely covered, in the refrigerator for up to 3 days — the whipped cream filling needs to stay cold. Let it sit at room temperature for 10 to 15 minutes before slicing for the best texture. The unfrosted, filled log can be wrapped and frozen for up to 1 month; thaw in the fridge, then frost and decorate before serving. Dust with fresh powdered sugar just before it goes to the table.

Frequently asked questions

Why did my cake crack when rolling?

It was likely rolled too late or overbaked. Roll it up in the towel while it's still warm and pliable, and bake just until the top springs back.

Can I make a yule log ahead of time?

Yes. Fill and roll it a day ahead and keep it chilled, then frost and decorate on the day. You can also freeze the filled log for up to a month.

Can I use store-bought whipped topping?

Freshly whipped cream tastes best and holds beautifully, but stabilized whipped topping works if you're short on time.

How do I get the bark texture?

Frost the log in chocolate buttercream, then drag a fork lengthwise down the cake to create ridges. A final dusting of powdered sugar makes it look like a snowy log.
