Christmas chocolate buttercream Yule log / Buche de Noel tutorial & Vanilla Swiss Roll Recipe

Yule Log / Buche de Noel cake tutorial - buttercream tree bark, pinecones, mushrooms & more | ffeabysawsen

Nothing says “Christmas” more than a beautifully decorated Yule log.  This year I decided to take it a step further than the well-known Swiss roll cake covered in chocolate frosting, dusted with icing sugar and at most graced with a sprig of holly… I’ve gone all-out, and piped a full festive log cake version of my most popular tree stump cake video.  As well as the mini piped mushrooms and toadstools, I’ve added pinecones, spruce needles and some festive red berries for that Christmas feel.  The result is a super cute and unique take on a much loved favourite, I hope you’ll like this as much as I do 🙂

Take a look at my all new “recommended tools & products” list if you’d like to see which natural and gel colours I used.  I know my previous Amazon store was horrendous to use – I couldn’t even figure it out myself so I’ve listed everything on my own site for your convenience 🙂  Please do check it out.

Products I Recommend



  1. Bake a swiss roll, or use a store bought one.  See the end of the post for the recipe I used.
  2. Prepare half a batch of my buttercream, links above, and colour using natural or gel colours.  The recipe for chocolate buttercream is in the “flavour variations” section of the second post.
  3. Divide the buttercream into piping bags fitted with the appropriate couplers or tips.
  4. Pipe toadstool caps and pine cones as shown in the video onto parchment paper and freeze solid.
  5. Prepare some cake dough using pound cake, Victoria sponge or store bought cupcakes, using my video tutorial (the link is here)
  6. Mould the cake dough into small branches as shown and adhere with buttercream.  Coat the ends with light brown buttercream, and use a fork to give a wood grain effect.
  7. Pipe tree bark on the cake using your star tip as shown in the video.  Chill the cake until the buttercream is solid.
  8. Pipe toadstools, tree mushrooms, branches and pine needles as shown.  Add the piped pine cones then accentuate with berries.
  9. Dust the cake with coconut flour (or powdered sugar if you prefer) prior to serving.


Swiss Roll cake recipe:

I used Michael Lim’s recipe from YouTube.  Here are the ingredients:

6 medium size Egg Yolks
60 grams Milk (that’s 1/4 US cup)
60 grams Oil (1/4 cup again)
1/2 teaspoon Salt
1 teaspoon Vanilla Essence
120 grams Plain Flour (about 1 cup minus 2 tablespoons)
6 medium size Egg Whites
1 teaspoon White Vinegar
120 grams Fine Sugar (about 1/2 cup + 1 tablespoon)

Pan size: 37cm x 24cm (about 14″ x 9″)

Baking temperature & time: 120°C ( 250°F)for 20 minutes then 150 °C (300°F) for 8 minutes

You can watch the method in Michael’s wonderful video here:

Allow the cake to cool fully and frost with a thin layer of buttercream prior to rolling.  Chill before using in my tutorial.

That should be all you need to know to make your own super cute and festive Yule log cake 🙂  Thank you for watching, have a great Christmas & stay tuned for more tutorials to come!
