Ingredients For This Keto Buche de Noel

The ingredients you need to make this keto Buche de noel are basic and easy to find. You probably have some of them in your kitchen:

For The Cake Layer

  • Almond Flour – use superfine blanched almond flour for a better texture.
  • Sweetener – I used powdered erythritol for this recipe, but you can also use Allulose, Monk Fruit, or your favorite keto sweetener.
  • Cocoa Powder – Of course, sugar-free! Use the best quality cocoa powder that you can find.
  • Gelatin – it helps to have a more flexible layer cake.
  • Eggs – must be separated to give volume and softness to the cake.
  • Vanilla Extract – To guarantee that the flavors don’t fade while baking, use the best vanilla extract you can find.
  • Cream of Tartar – if you don’t have any, you can replace it with white vinegar.

Mascarpone Whipped Cream Filling

  • Mascarpone Cheese –  you can replace it with cream cheese. But I recommended mascarpone because it’s thick, creamy, and has a neutral flavor that works well as a mousse-like filling with whipped cream.
  • Heavy Cream – You can replace it with coconut cream as well.
  • Sweetener – you have to sift to avoid any lumps in the filling.
  • Vanilla Extract
  • Salt – to enhance the flavors.

Whipped Chocolate Ganache

  • Chocolate – you will need unsweetened chocolate.
  • Heavy Cream 

How To Make This Keto Buche de Noel

This Keto Buche de Noel is easy to make by following a few simple steps. So, even though it appears to be a lot of effort, it’s not that complicated.

Make The Cake Layer

  1. Combine all the dry ingredients in a bowl. Then mix the egg yolks with sweetener and vanilla extract until creamy.
  2. Add the white eggs, cream of tartar, salt, and sweetener to a different bowl and mix until fluffy.
  3. Fold the egg yolks gently into the white eggs, then add the dry mixture and mix slowly.
  4. Line a baking pan with parchment paper and spread the cake batter evenly. Try to distribute it thinly and evenly since the more uniform it is, the more uniformly it will cool and roll.
  5. Bake it for about 15 minutes or until the top springs back when lightly pressed.
  6. Use the parchment paper and roll it up slowly and gently while it’s still warm. Then, allow the cake to cool completely.

Make The Filling

  1. Add all the ingredients to a mixing bowl and mix with an electric mixer for 2 minutes. Place in the refrigerator until ready to use.

Make The Whipped Chocolate Ganache

  1. Add the heavy whipping cream to a saucepan and bring it to a boil.
  2. Pour the cream over the chopped chocolate and set aside for one minute.
  3. Then mix quickly with a whisk until you have a thick and shiny chocolate sauce.
  4. Let the sauce cool for 5 minutes at room temperature, then for two more minutes in the refrigerator.
  5. Take the chocolate sauce out of the fridge and, with the help of a mixer, start mixing until the consistency becomes frothy and the color changes.

Asamble The Buche de Noel

  1. Unroll the cake once it has completely cooled, being cautious not to break it. Spread the whipped cream evenly. Carefully roll the cake into a log, spread the chocolate ganache, and dust with powdered sweetener.

Tips For Making The Best Keto Buche de Noel

  • Spread the batter using a silicone spatula and give it a good shake to level out the ridges left by the spatula.
  • If you can’t find mascarpone, you can use the same amount of cream cheese.
  • Remember to roll your cake in a kitchen towel while it’s still warm. When you wrap it up again with the filling, this step will prevent any cracks.
  • You can add some fruits to the filling, like strawberries, raspberries, or blueberries.

Storing Ideas

  • Freezer: If you also choose to freeze it. Transfer the cake to a parchment sheet or plate in the freezer for 1-2 hours. Then, once the cake is completely frozen, take it from the freezer and wrap it with plastic foil before placing it in an airtight container.

 To defrost it, remove the plastic wrap over the cake and place it in the fridge overnight before serving.

    This is a nice tasting recipe and I made it exactly as written, but unfortunately my cake cracked when I rolled it, and there seemed to be way too much mascarpone filling and ganache for the amount of sponge… I had loads left over. The ganache hid the cracks somewhat, but I don’t see how I could’ve filled in any more mascarpone filling inside without the whole thing coming apart and spilling out. Thanks for sharing, nonetheless, and maybe some day I’ll be able to make a Yule log that looks as nice as yours!
