Yule Log: Where the Tradition Comes From
Why do we serve a Bûche de Noël (Yule Log) for dessert at Christmas in France? The tradition goes back to an ancient custom, when families would burn a large wooden log in the fireplace to bring protection and good luck to the home during the festive season.
Over time, this tradition evolved into a dessert: a sponge cake, rolled and filled with chocolate and decorated to imitate the bark of a wooden log. What’s fascinating is that I’ve never seen this tradition anywhere else but in France!
The Classic Bûche de Noël in 3 Steps
Baking a Yule log can seem intimidating, but it becomes quite simple as soon as you know how each part fits together.
- 1. Sponge cake: This is a light, rectangular sponge cake that stays very soft. It’s rolled in a damp cloth as soon as it comes out of the oven so it can take shape without cracking.
- 2. Chocolate filling: You have two options: a rich chocolate buttercream or a chocolate ganache – my favorite because it’s lighter and even more chocolaty. For my ganache, I use a mix of dark and milk chocolate-
- 3. Decoration: On its own, it’s just a roll so the decoration is what brings the “Bûche” to life. Score the outside with a knife, then add some ornaments on top, I like to decorate with sugared cranberries and rosemary (instructions here).
5 Tips for a Perfect Christmas Yule Log
Before we begin this classic Bûche de Noël, let me give you five quick tips to ensure everything goes smoothly. In baking, it’s often the small details that make all the difference!
- Bring the egg to room temperature. This is very important you want your egg whites to whip up perfectly.
- Work very gently with the sponge cake batter so it stays soft and airy. Fold in the egg whites with a spatula, and remember to sift the flour to avoid lumps.
- Check the temperature of the chocolate. Chocolate should never exceed 55°C, otherwise it will burn and dissociate from the cream. Find out more about my tips for melting chocolate.
- Roll the sponge cake immediately after baking in a damp towel. It should still be warm so that it retains its shape and doesn’t crack.
- Let the log rest in a cool place before serving. Ideally, prepare it the day before or in the morning for the evening: the flavors deepen and the texture sets perfectly.
And for decoration? I like to add a few sugared cranberries and sugared rosemary, they only take 5 minutes to prepare and are super pretty!

Ingredients
For the sponge cake
- 4 eggs
- 1/2 cup granulated sugar 120g
- 3/4 cup all-purpose flour 120 g
- A few drops of lemon juice
For the chocolate ganache
- 5 oz dark chocolate 150 g
- 3.5 oz milk chocolate 100 g
- 1 cup full-fat heavy cream 240 ml
- 3 tbsp unsalted butter
Decoration
- A few sugared cranberries
- 3 sprigs sugared rosemary
- A few fresh redcurrants or decorations of your choice
Instructions
Prepare the ganache
- Melt the chocolate in a water bath (bain-marie) or in the microwave. It doesn’t have to be completely melted: the hot cream will finish the job.
- Heat the heavy cream in a saucepan, without boiling it (approx. 105°F / 40°C).
- Pour the warm cream over the chocolate and stir gently you obtain a smooth texture.
- Add butter and mix until fully incorporated. Let cool at room temperature, then pleace in the fridge for at least 2 hours.
Prepare the sponge cake
- Once the ganache begins to firm up, move on to preparing the sponge cake. Preheat the oven to 350°F / 180 °C (convection 325°F / 190 °C). Line a 17×12 inch (28 x 30cm) rimmed baking sheet with parchment paper.
- Separate the whites from the yolks. Whip the yolks with 3/4 of the sugar until the mixture whitens and becomes frothy.
- Whisk the egg whites with a few drops of lemon juice and once they start to rise, add the remaining sugar while you continue until they are stiff.
- Fold a large spoonful of stiff egg whites into the sugar-yolk mixture, whisking well to loosen it. Then fold in the remaining egg whites in three batches, mixing gently with a spatula.
- Sift in the flour in two or three additions to keep the batter airy.
- Spread the batter on the baking sheet to a maximum height of 0.5 to 1 inch (1 to 2 cm). Place in the oven for 10 to 12 minutes: the cake should remain soft and just lightly golden on top.
- Once out of the oven, place a damp cloth over the top, turn the tray over, remove the baking paper and immediately roll the still-warm sponge cake into shape. Place the “seam”, the end of the roll, underneath, so that it stays closed during cooling.
- Leave to rest for 10 minutes, then gently unroll.
Assemble the Bûche
- The ganache now has the texture of a spread. Spread a thin layer of ganache over the sponge cake.
- Re-roll the log, tightening slightly.
- Cover the log with the remaining ganache. Score lightly with a fork to imitate the bark of a log. Trim the ends with a sharp knife for a nicer result.
- Let the log rest in a cool place for at least two hours before serving.
- Decorate with sugar-coated cranberries, frosted rosemary and a few redcurrants just before serving.

How to Fix a Yule Log: 3 Common Issues Explained
Even an “easy” Yule Log can trick you now and then… Here are the three most common issues and how to avoid them.
1. My sponge cake breaks
Don’t panic, you can see it on the video I posted on Instagram, it happens to me sometimes too, but at the end it’s no longer visible! If it’s just a small crack, roll it gently anyway: the ganache will stick to it and you won’t see anything once the log is decorated.
To avoid this happening again: make sure not to overbake the sponge cake and roll it as soon as it comes out of the oven, when it’s still warm and soft.
2. My ganache is too liquid
If your ganache is too runny, it’s often because it hasn’t cooled enough. Always check the texture before preparing the sponge cake, it should be thick and spreadable.
The solution? If your sponge cake is already ready, leave it rolled in its damp tea towel (don’t unroll it) and leave the ganache cool a little more.
If you’re in a hurry, place the ganache in the freezer for 20 to 30 minutes, stirring it once or twice to check the texture, but no longer than that, otherwise it may suddenly set.
And above all: never pour a runny ganache over the sponge cake, as it will impregnate it too much and your log won’t hold its shape.
3. My log doesn’t hold its shape very well
This often happens when there’s a little too much ganache, or if the cookie is too warm when assembled.
The solution? Try placing your log in the freezer for 15 to 20 minutes, giving it the shape you want: it will firm up quickly and should hold together perfectly.
FAQ Bûche de Noël
The secret is not to overbake it: the sponge should stay flexible and lightly golden. As soon as it comes out of the oven, roll it immediately in a damp cloth (without the baking paper) so it holds its shape without cracking.
The sponge cake is ready when it is elastic to the touch and springs back when lightly pressed. It should be just just a little golden on top: if the edges turn brown, it’s already overcooked and may break.
Place it on a rigid surface, such as a rectangular dish or a piece of cardboard. Cover it with a box, a suitable lid or – my favorite tip – an upside-down cake tin that’s larger than the log so it doesn’t touch the coating. Another trick: before you leave, freeze the log for 20–30 minutes so it becomes firmer and easier to transport.
Store it in the fridge, it will keep for 2 to 3 days, well wrapped to prevent drying out. For longer storage, you can freeze it without the decoration. Then defrost overnight in the fridge before serving.
