Buche de Noel Cake (Yule Log Cake) is a classic Christmas Dessert

A Buche de Noel cake (or yule log cake) is commonly made from a yellow sponge cake and filled with chocolate buttercream. The outside is typically frosted with chocolate ganache and given a texture that resembles bark. It is often dusted with powdered sugar to resemble snow and sometimes has other decorations made from marzipan or meringue mushrooms.

The history of the Buche de Noel (as far as we know)

A yule log (not the cake) is a log that is burned in your fireplace during a winter festival. It was originally a Nordic tradition. Yule is the name of the old Winter Solstice festivals in Scandinavia and other parts of northern Europe, such as Germany. The log (sometimes an entire tree) would be carefully chosen and then brought into the house to be lit on one end, the rest extending into the house. A little of the log would be burned each day, extending through the 12 days of Christmas.

This sounds to me a lot like bringing a Christmas tree into the house. I’m glad we just put lights on our tree now and don’t light it on fire. I’ll stick to baking my yule log.

Depending on the region, various ingredients (such as salt or whine) were sprinkled on top of the log before burning to bring good luck or to ensure a good harvest for the following year. The ashes from the yule log where used in remedies and good luck potions.

But what does this have to do with a yule log cake? Well, little by little, the celebration of burning an entire tree in your living room died out. Maybe too many house fires? Eventually, people were just putting a single log into their fireplace to represent the yule log.

Sometimes there was no fireplace at all and a log was placed on the table as a centerpiece. It only makes sense that eventually someone decided a cake log would be much better than a real log. Obviously this dessert trend took off and became a very popular dessert all over the world.

In France, the buche de Noel was made from a flourless sponge cake, filled with chocolate whipped cream and then rolled into a log shape. It was then dusted with confectioners sugar to resemble snow on the log. We usually refer to bûche de Noël as a Yule log cake in America.

What day should you start baking your Buche de Noel?

Let’s talk about the process of making this cake. Plan on doing some things the day before decorating to make your life easier.

Day 1:

  • Make ganache and let it sit at room temperature
  • Make roll cake sponge, fill with buttercream and chill overnight
  • Make meringue mushrooms

Day 2:

  • Assemble your Buche de Noel cake and chill at least one hour before serving.
  • Dust with powdered sugar right before serving.

How to make the sponge

Making a roll cake sponge is not overly complicated but there are some things you will want to keep in mind for success.

  1. Make sure you whip your egg/sugar mixture to the ribbon stage. The ribbon stage is when the batter triples in size and sits on top of itself when you drizzle it in ribbons from the whisk.
  2. Sift the flour onto the egg mixture. Fold in your flour gently or you risk losing all the air in your sponge cake.
  3. Spread the batter all the way to the edge of your pan lined with parchment paper. No need to grease the pan.
  4. Don’t overbake your cake or your edges will be dry and crack when you try to roll it up.
  5. Roll your cake length-wise so it’s longer so that you have enough to cut off the end and it won’t be too short.
  6. Roll your cake right out of the oven with a tea towel. When the cake is warm it helps the cake retain it’s round shape as it cools, reducing the chances of cracking later.
  7. Let your cake chill overnight before slicing for prettier slices.

How to assemble a Buche de Noel

Once your sponge cake has cooled for at least an hour. You can carefully unroll it and fill the inside with a layer of chocolate buttercream, chocolate ganache.

Sponge cake is not super moist so if you want it moister, brush the surface with simple syrup first and use a filling like chocolate honey mousse or whipped cream. Add cocoa powder to the whipped cream to make it chocolate. Then roll the cake back up nice and tight so there are no gaps in the filling.

Place the cake into the freezer for about an hour or into the fridge overnight to chill the filling.

Cut the ends of the roll cake off to reveal the swirl of filling. Then cut off one more piece of the roll cake at a slight angle and place on the side of the roll to represent a branch.

Frost the outside of the Buche de Noel with chocolate ganache. Decorate the outside with some of your meringue mushrooms, fresh cranberries and sprigs of rosemary. Dust the whole thing lightly with some powdered sugar to look like snow.

Chill before serving. The Buche de Noel cake lasts for three days in the fridge.

Instructions

Buche de Noel Sponge Cake Batter Instructions

  • Preheat your oven to 400ºF (204ºC) with the oven rack in the center.
  • Line a sheet pan (13×18″) with parchment paper.
  • Next, fill a saucepan with 2-3″ of water and bring it to a boil over medium-high heat until boiling.
  • Then, reduce the heat to medium or until the water is simmering.
  • In the bowl of your stand mixer, place the eggs, granulated sugar, and salt and blend together with a whisk.
  • Next, place the bowl with the mixture on top of your simmering water. Do NOT let the bottom of the bowl hit the water.
  • Using your whisk, stir the egg mixture slowly until the sugar granules dissolve (about 110ºF or 43ºC).
  • Then, remove it from heat.
  • Attach your bowl to your stand mixer with the whisk attachment.
  • Add in your vanilla and whisk on high for 5-7 minutes until you reach the ribbon stage (see notes below). The mixture should triple in volume and lighten in color.
  • Sift in 1/3 of your flour mixture and fold (see notes) the flour in gently without damaging the structure of your egg mixture. Repeat two more times with the flour until just combined.
  • Spread the cake batter evenly into your parchment-lined sheet pan, and then spread it with an offset spatula or knife all the way to the edges of the pan. Do not grease your pan.
  • Bake the cake at 400ºF (204ºC) for 8 minutes.
  • Then, remove the cake from the oven and place it onto a cooling rack.
  • Immediately use a paring knife to carefully cut the edge of the sponge away from the sides of the pan.
  • Dust the surface of the cake with powdered sugar.
  • Next, place another piece of parchment on top of the cake, and then another cooling rack, and flip over to release the cake from the pan.
  • Remove the parchment paper carefully, and dust the surface with more powdered sugar.
  • Place a tea towel over the top of the cake and carefully roll into a spiral going lengthwise.
  • Finally, place it into the fridge to cool for one hour before filling it with your frosting. For more tips and tricks on making roll cakes, be sure to read my roll cake tutorial blog post.

Chocolate Buttercream Frosting Instructions

  • Start by sifting your powdered sugar and cocoa powder into the bowl of your stand mixer to remove any lumps. The cocoa powder especially loves to clump up and make these ugly specks in the finished buttercream.
  • Now, add in your pasteurized egg whites (yes, they need to be pasteurized). If you cannot get any pasteurized egg whites, you can make my chocolate Swiss meringue buttercream instead.
  • Mix everything together on low speed with the whisk attachment to combine it.
  • Then, mix on medium speed (setting 2 on my Bosch Mixer, setting 4 on a KitchenAid) for 3-5 minutes to help the powdered sugar and cocoa powder dissolve properly.
  • Next, add room temperature butter and mix it for 5-10 minutes on high speed.
  • Next, you want to turn up the speed to high and begin whipping in air! I whip mine for 5-10 minutes. Once it no longer tastes buttery, it’s done.
  • Switch to the paddle attachment and mix it on low speed for 10-15 minutes. This is totally optional but will help to remove excess air bubbles and make the buttercream really smooth.
  • Finally, you will switch to the paddle attachment and mix it on low speed for 10-15 minutes (totally optional) to remove excess air bubbles and make the buttercream really smooth. 

Ganache Frosting Instructions

  • Measure out your chocolate and chop it finely if it’s in big pieces so that it melts evenly.
  • Heat your cream on the stovetop until steam just begins to rise from the surface. Whisk occasionally to prevent burning. Do not walk away or your cream could boil over. 
  • Pour your hot cream over the chocolate and push the chocolate down so it’s all under the surface of the cream. Let the chocolate and cream sit for 5 minutes. 
  • Whisk the cream and chocolate together until it’s smooth. Start with small circles in the center until the chocolate and cream start creating an emulsion.
  • If you have lumps or un-melted chocolate, you can use an immersion blender to make your ganache super creamy and lump-free. 

Meringue Mushroom Instructions

  • First, preheat your oven to 225ºF (107ºC) and line a baking sheet with parchment paper.
  • Bring 2 inches of water to a simmer in a pot.
  • Place a clean stainless steel mixing bowl over the water. It should not touch the water. 
  • Combine your egg whites and sugar and whisk to combine. Occasionally whisk as it’s heating to distribute the heat and dissolve the sugar. 
  • Once your egg whites are at 110ºF (43ºC) (or when you don’t feel any grains of sugar between your fingers) you’re ready to whip.
  • Place the bowl on your stand mixer with the whisk attachment.
  • Whisk on medium speed (setting 2 on my Bosch Mixer, setting 4 on a KitchenAid) for one minute.
  • Then, add in the cream of tartar, salt, and flavoring. 
  • Next, bump the speed up to high and let it whip until you reach STIFF peaks. 
  • With a round piping tip, place your meringue into a piping bag and snip off the tip.
  • Pipe your stems and caps (see the video in the recipe card for more tips on these).
  • Bake them for 60 minutes, and then turn off the oven (but do not take out the cookies).
  • Let them sit in the oven until they are completely cold. I like to leave mine in overnight.
  • Poke a hole in the base of the mushroom and add a tiny bit of ganache or melted chocolate in the hole.
  • Then, place the cap on the stem.
  • Next, combine cocoa powder and vanilla.
  • Splatter the tops of the mushrooms with a stiff paintbrush.

Buche de Noel Cake Assembly Instructions

  • Once your sponge cake has cooled for at least an hour, you can carefully unroll it and then fill the inside with a layer of chocolate buttercream.
  • Then, roll the cake back up nice and tight lengthwise so there are no gaps in the filling.
  • Place the cake into the freezer for about an hour or into the fridge overnight to chill the filling.
  • Cut the ends of the roll cake off to reveal the swirl of filling.
  • Then, cut off one more piece of the roll cake at a slight angle and place it on the side of the roll to represent a branch.
  • Frost the outside of the Buche de Noel with chocolate ganache.
  • Decorate the outside with some of your meringue mushrooms, fresh cranberries, and sprigs of rosemary.
  • Dust the whole cake lightly with some powdered sugar to look like freshly-fallen snow.
  • Finally, chill before serving.

Notes

The ribbon stage is when your egg mixture triples in volume, lightens in color and when spooned onto itself, it forms ribbons of batter that stay on the surface before slowly dissolving back into itself. 
Fold the batter by running the spatula around the outside edge of the batter and the bowl and then gently lift the batter onto itself. This allows the batter to mix without damaging the delicate structure. 
Important Things To Note Before You Start
  1. Use a scale to weigh your ingredients (including liquids) unless otherwise instructed (Tablespoons, teaspoons, pinch etc). Metric measurements are available in the recipe card. Scaled ingredients are much more accurate than using cups and help ensure the success of your recipe. 
  2. Practice Mise en Place (everything in it’s place). Measure out your ingredients ahead of time and have them ready before you start mixing to reduce the chances of accidentally leaving something out.

  1. Ooooh, I’ve always wanted to make one of these! Thank you for demystifying the Buche de Noel! I hope that I have time to make one this year.

    I love that you seem more relaxed in your newer videos and are revealing more of your personality. I laughed right along with you.
    Merry Christmas to you and your family.

    1. Thanks so much! I am trying not to take myself so seriously anymore and just have more fun. I am so glad you are enjoying the videos too!

  2. Hi Liz!
    in the video, you mentioned the pan size to be 12×18″ but in the recipe it says 9×13″.

    Which one should we use?

  3. Hi,
    Your recipe says you use 8 eggs but on your video you use six. Which one is correct?

    1. Hi there, the buche de noel cake pan is slightly bigger than the roll cake pan so I made the recipe a bit bigger to make sure it made enough 🙂

  4. I made this cake yesterday and everything was super delicious . I’ve made your regular easy butter cream before but this chocolate was is even more delicious . My only problem was my sponge cake was very dry. Any advice on what I may have done wrong for it to end this way ?

    1. Sponge cake is not moist like a butter cake, it can be dry tasting. If you want it to be moister you can brush the surface with simple syrup before you fill it with buttercream

  5. Recipe says 8 oz cake flour but the metric conversion says 227 g? I thought that 1 cup of flour was about 90 g? Which is correct?

  6. Giving this cakena shot today! My only changes are with flavor. Ill be using a chocolate sponge, a green mint buttercream for thr filling, and a beautiful chocolate ganache! Cant wait!
