How to Make a Yule Log Cake: Simple Step-by-Step Guide 2026

Learning how to make a yule log cake, called a bûche de Noël in French, means rolling a thin chocolate sponge into a cylinder, filling it with whipped cream, coating it in chocolate ganache, and texturing that with a fork so it looks like a rustic woodland log. It has four parts: sponge, filling, ganache, decorations. Plan on roughly three hours, most of which is waiting.

Is a yule log hard to make? Not really. The one genuinely tricky moment is rolling the sponge, and it becomes predictable once you learn to roll it while it is still warm and let it cool fully in the roll rather than flat.

How to Make a Yule Log Cake in Six Steps

1. Bake a thin chocolate sponge in a lined jelly-roll pan at 350°F (175°C) for 12 to 15 minutes.
2. Lift the sponge on its parchment and roll it up while it is still warm.
3. Let the rolled sponge cool completely in its towel, then unroll and spread it with whipped filling.
4. Re-roll tightly, wrap, and chill for at least two hours.
5. Pour hot cream over chopped chocolate, chill until spreadable, then coat the log and scrape it into bark texture.
6. Chill, slice one angled piece for the branch, and finish with powdered sugar, berries, and rosemary.

What You Need to Make a Yule Log Cake

Everything comes down to a pan, a few hand tools, and four ingredient groups. Grab the pan first, because the wrong size is the most common reason a log comes out too short to cut a branch from.

Equipment

• A 17 by 12 inch (43 by 30 cm) jelly-roll pan. An 18 by 13 inch (45 by 33 cm) half sheet works too and leaves more length for the branch.
• Parchment paper, cut to fit the pan, plus a second sheet for rolling.
• A clean, thin cotton tea towel for guiding the roll.
• An offset spatula, a fine mesh sieve, a fork, and a sharp serrated knife.
• A wire rack, and a cake board or platter for serving.

Chocolate Sponge

• 4 large eggs, room temperature
• 3/4 cup (150 g) granulated sugar
• 1/2 cup (120 ml) neutral oil, like canola or grapeseed
• 3/4 cup (180 ml) hot water
• 1 cup (125 g) all-purpose flour
• 1/2 cup (43 g) Dutch-process cocoa powder
• 1 teaspoon baking powder, 1/2 teaspoon fine salt
• 1 teaspoon vanilla extract and 1 teaspoon instant espresso powder

Whipped Filling

• 8 oz (225 g) mascarpone cheese
• 1 cup (240 ml) heavy whipping cream
• 1/4 cup (30 g) powdered sugar and 1 teaspoon vanilla
• A pinch of flaky salt, which is what keeps the sweetness in check

Ganache and Decorations

• 6 oz (170 g) bittersweet or semisweet chocolate, chopped
• 1 cup (240 ml) heavy whipping cream for the ganache
• Powdered sugar, fresh cranberries, and rosemary sprigs
• Optional: meringue mushrooms, piped with a small round tip

Swaps and Shortcuts

For a nut-free version, skip any hazelnut or praline and use plain mascarpone or a cream-cheese filling. If you like a boozy note, a tablespoon of coffee liqueur stirred into the filling works, but leave it out for an alcohol-free bake and add a splash of cold strong coffee or an extra teaspoon of vanilla instead. A boxed chocolate cake mix works: use one 15.25 oz box, prepare it with 3 eggs, 1/2 cup water, and 1/3 cup oil, spread it thin on the pan, and bake 11 to 13 minutes.

A vanilla version replaces the cocoa with an equal weight of flour and uses white chocolate ganache with a vanilla bean filling. For mini logs, bake the same sponge in a 13 by 9 inch (33 by 23 cm) pan and slice it into two short rolls.

Step-by-Step: How to Make a Yule Log Cake

Prepare the Cake Pan and Oven

Heat the oven to 350°F (175°C) and set the rack in the middle third of the oven. Lining the pan while it is cold keeps the parchment flat and stops the sponge from gripping the metal edge.

Lay a sheet of parchment in the pan and press it firmly into the corners so it lies flat with no wrinkles. Rub a little oil over the surface and dust it lightly with cocoa powder or the sugar measure. A wrinkle in the parchment prints a stripe straight down the outside of your log.

Give the oven ten full minutes to preheat. An oven that is still climbing in temperature bakes the edges of the sponge hard before the middle sets, and hard edges are exactly what crack when you roll.

How to Make the Chocolate Sponge

Whisk the eggs, sugar, oil, vanilla, and espresso powder together for two full minutes until the mixture is pale, thick, and falls off the whisk in a ribbon. Hand mixers work; a stand mixer saves your arm.

Sift the flour, cocoa, baking powder, and salt in twice. Fold the dry ingredients into the wet in two additions, and stop mixing the moment the last streak of flour disappears. Overmixing develops gluten and gives you a rubbery sheet that cracks instead of rolling.

Pour the batter into the lined pan and spread it into the corners with an offset spatula. Tilt the pan and tap it once on the counter to push out the big air pockets. Bake for 12 to 15 minutes, until the surface springs back when you press a fingertip near the edge and a tester inserted in the middle comes out with only a few moist crumbs.

Take it out while the centre still looks a shade underdone. Sponge that bakes to a deep brown crust loses the elasticity you need for the roll.

Add the Filling and Roll the Cake

Lift the sponge out of the pan by the parchment and lay it on your work surface. Drag a clean, thin tea towel across the top and roll the sponge up inside the towel, starting at one short end, using even pressure.

Roll slowly. Push from the outside edge rather than pulling the far end, which is what makes the roll tighten into a cone. Once it is a cylinder, leave it seam-side down in the towel and let it cool completely, about 45 minutes.

Cooling it rolled is not optional. The sponge finishes setting in its spiral shape, and a log that cooled flat will spring open and split along the seam when you fill it.

Meanwhile whip the filling. Beat the mascarpone just until smooth, add the heavy cream, powdered sugar, vanilla, and salt, and whip on medium-high until it holds a soft peak that just flops over. Spread it in a generous layer, but leave a 1 inch (2.5 cm) border at the far edge, since that strip is what seals the seam.

Unroll the cooled sponge carefully, fill it, and re-roll using the towel again. Press the seam-side down and wrap the whole log in plastic wrap.

Bake or Chill the Log

Chill the filled log seam-side down for at least two hours, or overnight. If you prefer a firmer log that slices into cleaner spirals, freeze it for 30 minutes before the final coating.

A short bake after rolling is the old French pastry-school step: 350°F (175°C) for 8 to 10 minutes sets the filling and gives the sponge extra grip so it will not slide apart. Chilling achieves nearly the same result without drying the sponge out, which is why most home bakers I know skip the second bake.

Make the Chocolate Ganache and Coat the Log

Pour the 1 cup of heavy cream in a saucepan and bring it just to a simmer, with the first bubbles breaking the surface. Chop the chocolate finely while it heats, then pour the cream over it and let it sit for one full minute without stirring.

Stir from the centre outward until the chocolate disappears and the ganache is glossy. Chill it until it thickens to a soft, spreadable consistency, about 20 to 30 minutes, stirring once halfway through. The test is simple: a finger dragged across the surface should leave a clean line that holds its edge.

If it runs off the log and pools on the plate, it needs more chilling, not more chocolate. A splash of cold cream and ten more minutes is the usual rescue.

Set the chilled log on a rack over a baking sheet and pour the ganache over the top. Turn it as you go so the ends and underside are coated, then use an offset spatula to sweep the surface smooth.

Add the Bark Texture and Festive Details

Drag the tines of a fork lightly along the log in uneven, vertical strokes to pull the ganache into bark lines. A pastry wheel gives chunkier ridges, and a small knife makes the deep slashes used for the cut-off branch end.

Cut a 3 to 4 inch (7.5 to 10 cm) piece from one end of the log and angle the cut. Set it against the log so the exposed spiral faces out, ganache that joint, and run a few lines through the cut face to suggest the rings of a cut branch.

Dust powdered sugar through a fine sieve for snow. Sugared cranberries and a rosemary sprig or two are the classic garnish, and small meringue mushrooms, piped and dried on the tray overnight, turn a rustic log into the showpiece everyone photographs.

Chill, Slice, and Serve

Chill the decorated log for at least 30 minutes so the ganache firms. Wipe the knife with a hot damp cloth between every slice, because a warm blade melts the ganache and drags it across the spiral.

Cut with a long serrated sawing motion from one end to the other rather than pressing straight down. Serve at room temperature, and take it out of the fridge about 20 minutes before eating so the ganache softens and the sponge tastes of something more than cold cream.

Common Mistakes and Fixes

Almost every failed yule log comes down to one of five things: heat, timing, seal, ganache thickness, or humidity. Find the symptom below and fix that line first.

What went wrong	Why it happened	How to fix it next time
Sponge cracked or shattered while rolling	It was overbaked, or fully cooled before rolling	Bake 2 minutes less, check at 12 minutes, and roll while warm. Unroll and re-roll every 5 minutes as it cools.
Cake stuck to the parchment	Parchment was too tight or the sponge sat too long	Cool 5 minutes only, then peel the parchment back slowly at a low angle while you start the roll.
Log is loose and springs open	Cooled flat, or rolled too loosely	Always cool the sponge inside its first roll. Re-roll with firm, even pressure.
Filling oozes out of the seam	Filling spread to the very edge, or the log was sliced cold and fast	Leave a 1 inch border unfilled, and chill the finished log fully before cutting.
Ganache slides off and pools	Ganache was too warm or too loose	Chill until a finger-drawn line holds its edge, then spread in thin layers and chill between coats.
Meringue mushrooms weep or shrink	Humidity in the room	Add a tablespoon of powdered sugar to the egg whites, dry fully, and bake on low until crisp.

Make-ahead is straightforward. Bake and roll the sponge up to two days ahead, fill and wrap it, and refrigerate. Make the ganache a day ahead too, and rewarm it gently before use. A decorated log keeps in the refrigerator for up to 4 days and freezes undecorated for up to 3 months; defrost it in the fridge overnight, then add the ganache and snow on the day you serve.

Frequently Asked Questions

Where to Start With Your First Yule Log

Start tonight with the sponge. Get the pan lined, bake it two minutes under the time, and roll it while it is warm. Everything after that is forgiving, and once you see the spiral hold together, the frosting and bark are the fun part.
