- Milk
- Flour
- Cocoa
- A pinch of salt
- Egg yolks
- Egg whites
- Vinegar
- Sugar
- Hazelnut powder
- Raw skinless hazelnuts
- Sugar (for praline)
- Water (for praline)
- Fleur de sel or fine salt
- Gelatin
- Chocolate
- Hot cream

- Grape seed oil or neutral oil (like sunflower or peanut)
- Crushed toasted hazelnuts or almonds
- Salted butter caramel
- Toasted hazelnuts
- Crunchy chocolate pearls
- Homemade or commercial praline
Directions:
- For the Japanese chocolate Swiss Roll: Mix the oil and milk, and then add flour, cocoa, and salt. Incorporate egg yolks and mix. Whip egg whites with vinegar and gradually add sugar. Gently fold this into the previous mixture, followed by hazelnut powder. Spread the batter on a baking sheet lined with parchment paper and bake for 20 minutes at 170°C. Let cool slightly, roll in parchment and a towel, and set aside.
- For the hazelnut praline: Toast hazelnuts till uniformly colored, make a syrup with water and sugar, then add hazelnuts to caramelize. Spread on a non-stick surface, let cool, crush and blend until smooth, adding fleur de sel.
- For the hazelnut whipped ganache: Soak gelatin, melt chocolate and mix with hot cream. Add cold cream and hazelnut praline, blend, and let rest overnight in the refrigerator. Whip to a firm consistency the next day.
- For the Rocher glaze: Melt both chocolates, add grape seed oil and crushed hazelnuts. Let cool slightly.
- For the filling and assembly: Spread salted butter caramel over the cooled chocolate biscuit, followed by hazelnut whipped ganache. Add layers of hazelnut praline and more caramel, then gently roll the log. Freeze for 30 minutes, trim the ends, cover with rocher glaze, and decorate with hazelnuts and chocolate pearls.
- Optional: Add crushed hazelnuts on the Japanese biscuit or use a Viennese biscuit instead. For a velvet spray, spray a well-frozen log with brown velvet spray.
How to serve Chocolate Hazelnut Caramel Yule Log
Slice the log with a warm, sharp knife to preserve clean edges; each slice should reveal spirals of glossy ganache, ribbons of caramel, and flecks of praline. Serve on a chilled platter with extra toasted hazelnuts scattered around and a few crunchy chocolate pearls for drama. A small scoop of vanilla or lightly salted caramel ice cream pairs beautifully, or offer espresso for a bold counterpoint.
How to store Chocolate Hazelnut Caramel Yule Log
Keep the log chilled in the refrigerator, covered, for up to 4 days. For longer storage, freeze the assembled and glazed log (well wrapped in plastic and foil) for up to 1 month—thaw overnight in the fridge before serving. If you’ve used a velvet spray, keep it frozen until just before serving to preserve the finish.
Tips to make Chocolate Hazelnut Caramel Yule Log
- Room temperature ingredients make batter and ganache smoother—bring eggs and milk to a gentle room temp first.
- Fold egg whites gently to preserve airiness in the sponge; overmixing will flatten the roll.
- Chill the ganache mixture overnight as directed—this develops flavor and gives you the right texture to whip.
- Warm your knife under hot water and wipe it dry between slices for perfect, clean cuts.
- If your praline is too thick for blending, pulse it with a neutral oil to reach a spreadable consistency.
- Freeze briefly before glazing: a cold log helps the glaze set quickly and evenly.
Variations (if any)
- Swap toasted almonds for hazelnuts in the praline for a slightly different nutty character.
- Use a Viennese biscuit for a lighter, melt-in-your-mouth roll if you prefer a more delicate sponge.
- For a citrus twist, add a thin layer of orange marmalade beneath the praline to brighten the flavors.
- Make it nut-free by replacing praline with a crisp feuilletine layer and using toasted seeds for garnish.
FAQs
Q: Can I make parts of this recipe ahead of time?
A: Absolutely—prepare the hazelnut praline and whipped ganache up to 3 days in advance (ganache must be refrigerated). The sponge can be made a day ahead and kept rolled in parchment to retain moisture.
Q: My ganache didn’t set firmly—what should I do?
A: Chill it longer; sometimes it needs more time depending on room temperature. If it remains too soft, gently fold in a bit more melted chocolate chilled slightly, then refrigerate until the texture firms enough to whip.
Q: How do I prevent the sponge from cracking when I roll it?
A: Roll the sponge while it’s still slightly warm, using parchment and a towel to guide it. This “memory” helps it hold the roll; when filling, unroll carefully and re-roll gently.
Q: Can I substitute gelatin?
A: You can try agar-agar, but quantities and setting behavior differ. Gelatin gives a creamier, more elastic set in this kind of ganache; if you use agar, test a small batch first.
Q: Is there a vegan version?
A: To make it vegan, use plant-based milk and cream alternatives, a vegan chocolate with high cocoa content, and a vegan gelling agent like agar (with care). The texture will differ, so trial and adjustments are recommended.
