This Christmas Chocolate Carob Yule Log is made with sponge cake, filled with chocolate mousse and covered with a chocolate carob flavoured buttercream.

A Yule log (or bûche de Noël in French,  is a traditional Christmas dessert made of a yellow sponge cake which is shaped into a roulade  in order to create a chopped branch.

The word Yule is an archaic term for Christmas.

This dessert is of French origin. The French name of this recipe literally translates as “Christmas log”, referring to the traditional Yule log burned centuries past.

Originally, it was covered into icing sugar, to resemble snow, though now it is decorated with chocolate buttercream, to resemble a miniature actual Yule log.  A bark-like texture is often produced by dragging a fork through the buttercream.

This one is made with my basic sponge cake recipe, filled with Choocolate Mousse and decorated with a Chocolate and Carob Buttercream on top.

To make the sponge I make my own cake flour, which you will find in the above basic sponge cake recipe.

During Christmas, we are usually in Athens, where I have an old mixer, which is not very powerful and a hand mixer.  This is why I have to whisk the egg whites separately in order to make the sponge.  Alternatively, if you have a powerful mixer, beat the eggs (whole) with the sugar on high speed until white and fluffy.  Lower speed to minimum and add the remaining ingredients.

I cut two pieces from the roulade which were attached on the main log, one on the side and one on top and stuck together using the butteercream.

When making the sponge, the height of the batter should not be more than 1 – 2 cm before baking.  When it is baked, icing sugar is sprinkled on top, as the icing sugar will help so that it will not stick into one piece.  It should be rolled while still warm, so that it takes the shape of a roll.

When unrolling the sponge to remove the paper, if the sponge cracks, don’t worry as it will stick again when the buttercream is added on top.

Update: Christmas 2021

This year I decided to make a Yule Log again. It is based on the same recipe but modified as follows:

Sponge cake: I made a dark sponge but substituting some of the flour with cocoa.

The filling was made with whipped cream, cream cheese and chocolate.

Chocolate Cream Cheese Filling:

200 grams heavy cream

50 grams icing sugar

200 grams cream cheese Philadelphia

1/2 tsp vanilla essence

50 grams chocolate chips couverture

30 grams cocoa powder


125 grams heavy cream

125 grams darks chocolate couverture

50 grams butter


Beat the heavy cream with the icing sugar until peaks form.

Add the cream cheese and vanilla and mix to incorporate.

Melt the chocolate chips in the microwave at 640W for 2 minutes, 1 minute each time.

Sift the cocoa powder and add to the cream.  When the chocolate slightly cools add it to the cream and mix.

Open the sponge and add the cream.

Refrigerate for 1 hour, then cut the yule.

Add the Chocolate ganache on top and decorate as you like.

For the ganache, melt the chocolate in a bain Mari. Add the butter and mix. Finally add the heavy cream and mix until the ganache is smooth. Set aside to cool slightly and then cover the yule.
