The Bûche de Noël, or Yule Log, is a classic French Christmas dessert that has evolved from rustic tradition to refined pastry art. Originally shaped from a rolled sponge layered with cream and decorated to resemble a wooden log, it symbolised warmth and renewal during the festive season. Today, pastry chefs reinterpret the Yule Log in modern form — building it from delicate sponge layers, silky fillings, and glossy finishes inside elegant silicone moulds. This contemporary approach preserves the spirit of the original while elevating it into a sculpted mousse cake (entremet) — smooth, balanced, and visually striking.
Bûche de Noël (Yule Log) Entremet – Flavour & Design
This Bûche de Noël (Yule Log) entremet showcases a refined balance of flavour, colour, and texture — a modern take on the classic French Christmas dessert. The exterior is finished with a velvet pink coating, creating a soft, luxurious appearance enhanced by a scattering of freeze-dried raspberries that add brightness and natural tang. Inside, layers of raspberry and white chocolate mousse surround a vivid mandarin jelly insert, offering a refreshing citrus contrast. A light white chocolate sponge adds sweetness and structure, while a crisp shortcrust base provides texture and support. Crafted in the Silikomart Lana mould, this contemporary entremet captures the essence of the traditional Yule Log — sophisticated, festive, and visually captivating.

Below is a quick assembling video to help you visualise the process and understand how each component comes together. Watching the sequence will give you a clearer sense of structure, layering, and finishing — essential details for achieving a clean, professional presentation:

The quantities in this recipe are calculated to perfectly fill one Bûche de Noël mould of 1200 ml capacity. You will need approximately 230 g of sponge, 300 ml of mandarin jelly, and 600 ml of raspberry white chocolate mousse. Note that the actual volume of the mousse increases slightly after incorporating whipped cream, so the total yield will align closely with the mould’s full capacity, ensuring a clean, well-balanced assembly without excess.
Mandarin Purée – Simple Alternative to Professional Fruit Bases
You don’t need to buy professional mandarin purée for this recipe — you can easily make your own at home using the same method shown in my Blood Orange Tart recipe. Simply segment fresh mandarins, removing the membranes to keep the flavour bright and smooth, then blend until silky.
This method gives you a clean, natural purée with vivid colour and balanced citrus notes — ideal for mousses, jellies, or inserts. You can also substitute pomelo or grapefruit for a more aromatic or gently bitter variation, adjusting sweetness to taste.
