Bûche de Noël (French Chocolate Yule Log)

France's edible Christmas centrepiece: a light chocolate sponge rolled around silky buttercream, frosted to look like a bark-covered log, and dusted with snow. A showstopper that's far more achievable than it looks.

A chocolate bûche de Noël shaped like a log with fork-textured 'bark' frosting, a diagonal branch on the side, dusted with icing-sugar 'snow,' showing a spiral of cream when sliced.

The bûche de Noël descends from the pre-Christian tradition of burning a real Yule log through the winter solstice. As open hearths disappeared in the 19th century, Parisian pâtissiers reimagined the log as a rolled sponge cake, and it became the indispensable dessert of the French Christmas table — and of French-influenced kitchens around the world.

The bûche de Noël — the Yule log — is the dessert that ends Christmas dinner across France, and it carries a story older than the recipe. Before it was a cake, the Yule log was a real log, burned slowly through the darkest nights of the year. When hearths gave way to stoves in the 1800s, Parisian pâtissiers turned the ritual into pastry: a rolled chocolate sponge frosted to look like bark, dusted with sugar snow.

It looks like the work of a professional, but it’s really just a sponge, some buttercream, and a fork.

The sponge is all about air

This cake has no baking powder. Every bit of its lightness comes from the air you beat into the eggs, so whip the yolks until pale and the whites until glossy and stiff, then fold — never stir — to keep that air in. Spread it thin and even and bake it just until set; an overbaked sponge is what cracks.

Train the roll while it’s warm

The trick that saves the day: as soon as the sponge comes out of the oven, roll it up in a sugared tea towel and let it cool curled. This teaches it to bend, so when you unroll, fill, and re-roll it, it holds its shape instead of splitting.

Make it look like bark

Frost the whole log in chocolate buttercream, then drag a fork down its length for bark, stick a diagonal off-cut on the side as a branch, and chill. A snowfall of icing sugar right before serving — plus meringue mushrooms if you’re feeling ambitious — finishes the woodland effect.

Ingredients

Serves
10

For the sponge

  • 4 large eggs, separated At room temperature — they whip to far more volume.
  • 100 g caster sugar
  • 60 g plain flour
  • 30 g cocoa powder Good-quality, unsweetened.
  • 1 pinch salt

For the chocolate buttercream

  • 200 g dark chocolate, melted and cooled
  • 200 g unsalted butter, softened
  • 150 g icing sugar, sifted
  • 1 tbsp cocoa powder

For the filling

  • 200 ml double cream, whipped Optionally sweetened with 1 tbsp sugar and a splash of vanilla.

To finish

  • icing sugar, for dusting The 'snow.' Add a sprig of holly or meringue mushrooms if you like.

Method

Tap a step’s number to check it off as you go.

  1. Whisk the egg yolks with half the sugar until pale and thick. In a clean bowl, whip the whites to soft peaks, add the rest of the sugar, and whip to stiff, glossy peaks.

    Why: The cake has no raising agent — all its lift comes from the air beaten into the eggs, so both mixtures must be well aerated.

  2. Sift the flour, cocoa, and salt over the yolks and fold gently, then fold in the whites in three additions. Spread evenly into a lined Swiss-roll tin and bake at 200°C/400°F for 10–12 minutes.

    Why: Folding (not stirring) keeps the air in. A thin, even layer bakes fast and stays flexible enough to roll without cracking.

  3. Turn the hot sponge out onto a sugar-dusted tea towel, peel off the paper, and roll it up loosely with the towel inside. Cool completely rolled.

    Why: Rolling the cake while warm 'trains' it into a curl, so when you unroll and refill it, it won't crack.

  4. Make the buttercream: beat the soft butter with icing sugar and cocoa until fluffy, then beat in the cooled melted chocolate.

    Why: Adding the chocolate once it's cooled (but still fluid) keeps the butter from melting and splitting the cream.

  5. Unroll the cooled sponge, spread with the whipped cream, and re-roll without the towel. Trim one end on the diagonal and set it against the side as a 'branch.'

    Why: The diagonal off-cut, stuck to the side, is what turns a plain roll into a log.

  6. Cover the whole log in chocolate buttercream and drag a fork along it lengthwise to mimic bark. Chill at least 1 hour, then dust with icing sugar before serving.

    Why: The fork marks make the bark; chilling firms everything so it slices cleanly. The icing-sugar 'snow' goes on last so it stays bright.

Variations

  • Make-ahead

    Assemble and frost up to 2 days ahead and keep chilled; dust with icing sugar just before serving. It also freezes well, un-dusted, for up to a month.

  • Chestnut (crème de marrons)

    Fold sweetened chestnut purée into the cream filling for a classic French marron variation.

  • Coffee

    Add a tablespoon of strong espresso to the buttercream for a mocha log.

Serving & Storage

Frequently Asked Questions

How do I stop the sponge from cracking when I roll it?

Roll it while it's still hot, with a tea towel inside, and let it cool fully in that curled shape. This trains the sponge to bend. A thin, evenly baked sponge that isn't overcooked also stays far more flexible — overbaking is the main culprit behind cracks.

Can I make a bûche de Noël ahead of time?

Yes — it's an ideal make-ahead. Assemble and frost it up to two days before and keep it chilled, or freeze it for up to a month. Add the icing-sugar 'snow' only just before serving so it stays crisp and white.

What if my buttercream splits?

It usually means the butter was too cold or the melted chocolate too warm. Make sure the butter is properly soft and the chocolate is cooled to just-fluid. If it splits, keep beating — it often comes back together, or warm the bowl very slightly.
