Introduction
The génoise for Christmas Yule Log is a delicate and versatile sponge cake, designed to be rolled and filled, serving as the foundation for the beloved French holiday dessert, the Bûche de Noël.

Origins and History
The Yule Log, or Bûche de Noël, is a traditional French Christmas dessert that dates back to the 19th century. Inspired by the practice of burning a large log in the hearth during the winter solstice, this cake symbolizes warmth, unity, and celebration. The génoise, with its Italian origins, was adopted into French patisserie as the perfect base for the log-shaped cake, offering both flexibility for rolling and a neutral flavor that pairs beautifully with a variety of fillings.
What makes this recipe unique is its simplicity and adaptability. While it requires careful attention to detail, the result is a versatile cake that forms the heart of countless festive creations, from chocolate-filled Yule Logs to fruit-filled roulades.
Ingredients
Complete Ingredient List (Serves 6)
4 large eggs
120 g (½ cup + 2 tbsp) sugar
100 g (¾ cup) all-purpose flour
1 pinch of salt
Substitution Suggestions
Flour: Replace with gluten-free all-purpose flour or almond flour for a gluten-free alternative.
Sugar: Use coconut sugar for a hint of caramel or a sugar substitute for a reduced-sugar version.
Flavors: Add vanilla extract, almond essence, or citrus zest to infuse additional flavors into your sponge.
Decoration: Use natural food coloring or edible glitter to add a festive touch to your cake.
Instructions for Preparation
Step 1: Preheat the Oven
Preheat your oven to 180°C (350°F). Prepare a baking sheet by lining it with parchment paper to prevent sticking.
Step 2: Prepare the Egg Yolk Mixture
Separate the eggs:
Carefully separate the yolks from the whites, placing them in separate bowls.
Whisk the yolks and sugar:
In a large bowl, whisk the 4 egg yolks with 120 g of sugar until the mixture becomes pale and mousse-like. This step incorporates air, which contributes to the lightness of the génoise.
Step 3: Add the Flour
Sift the flour:
Sift 100 g of all-purpose flour to ensure a smooth, lump-free batter.
Combine with the yolk mixture:
Gradually add the sifted flour to the egg yolk mixture, stirring until fully combined. The mixture should be thick and smooth.
Step 4: Whip the Egg Whites
Add salt:
Add a pinch of salt to the 4 egg whites.
Whisk to stiff peaks:
Using an electric mixer, beat the egg whites until they form stiff peaks. You should be able to turn the bowl upside down without the whites falling out.
Step 5: Fold in the Egg Whites
Loosen the batter:
Add one-third of the whipped egg whites to the flour-yolk mixture. Stir briskly to loosen the batter.
Fold gently:
Add the remaining egg whites in two batches, folding gently with a spatula to maintain the airy texture.
Step 6: Bake the Sponge
Spread the batter:
Pour the batter onto the prepared baking sheet and spread it evenly using an offset spatula.
Bake:
Bake for 8 to 9 minutes, or until the sponge is lightly golden and springs back when touched.
Step 7: Roll the Sponge
Turn out the cake:
Remove the sponge from the oven and immediately invert it onto a clean, damp kitchen towel. Peel off the parchment paper.
Roll the sponge:
Using the towel to guide you, roll the sponge cake tightly while it is still warm. Let it cool completely in this rolled shape to prevent cracking.
Step 8: Fill and Decorate
Add the filling:
Once cooled, unroll the sponge and spread your desired filling evenly (e.g., chocolate ganache, buttercream, or jam).
Reroll the sponge:
Roll the cake back into a log shape, ensuring the filling stays inside.
Decorate:
Top with chocolate frosting, powdered sugar, or festive decorations such as holly leaves or edible glitter to complete your Yule Log.
Frequently Asked Questions
1. Why does my génoise crack when I roll it?
If the génoise isn’t rolled immediately after baking, it can lose its flexibility and crack. Always roll it warm, using a damp towel to help mold its shape.
2. Can I make the génoise in advance?
Yes, you can bake the sponge a day ahead. Wrap it tightly in plastic wrap to prevent it from drying out, and store it at room temperature.
3. Can I freeze the génoise?
Absolutely! Wrap the rolled or unrolled sponge in plastic wrap and aluminum foil, and freeze for up to 1 month. Thaw it at room temperature before filling and decorating.
4. How do I ensure my génoise is light and fluffy?
Be careful when folding in the egg whites. Use a gentle, sweeping motion to incorporate them without deflating the batter.
5. What are some creative filling ideas?
Classic: Chocolate ganache or vanilla buttercream.
Fruity: Raspberry jam, lemon curd, or fresh whipped cream with berries.
Festive: Spiced cream cheese frosting with cinnamon or nutmeg.
