This magical holiday sweet treat turns basic items into a gorgeous table centerpiece that blends old-world charm with modern flair. The soft chocolate sponge, filled with lush mascarpone cream and covered in smooth ganache, makes an edible work of art that celebrates Christmas customs from years gone by.
When I make this cake, I think about cold days in my grandma's kitchen where she showed me how rolling the just-baked cake in parchment stops it from breaking. The mix of chocolate and sweet sugar in the air always takes me back to those special times together.
Smart Ingredient Picking Guide
- Dark chocolate: Go for quality 60-70% cocoa for the best ganache feel.
- Mascarpone: Pick the full-fat kind and let it sit out before using.
- Eggs: Get them fresh and warm to room temp for better fluffing.
- Cocoa powder: Dutch-processed gives you darker color and richer taste.
- Heavy cream: Try to find one with at least 36% fat.
- Parchment paper: Grab good quality to keep things from sticking.
Clear Making Instructions
- Getting Your Cake Ready:
- Put your oven rack in the middle and heat to 350°F. Lay parchment in your jelly roll pan with extra hanging over the sides for easy grabbing later. Make sure it's smooth - bumps will show up on your cake.
- Working With Eggs:
- Split eggs when cold, then let them warm up for about 30 minutes. This helps them whip better. Don't mix even tiny bits of yolk with whites or they won't fluff up right.
- Whipping Up Your Meringue:
- Beat egg whites until slightly peaked, then slowly add sugar and keep beating until they're shiny and hold their shape. This usually takes 5-7 minutes. When you lift the beater, the peaks should stand tall.
- Making Your Chocolate Mix:
- Mix cocoa stuff into egg yolks with gentle folding until just mixed. Add meringue bit by bit in three parts, keeping as much air as you can. Your final mix should feel light and fluffy.
- How To Roll It:
- Spread mix evenly in your pan. Bake until it springs back when touched, around 12 minutes. Roll the hot cake right away with the parchment - this stops cracks and trains the cake to hold its shape.
- Creating The Creamy Filling:
- Whip mascarpone until smooth, then slowly add cream and vanilla. Beat until stiff but watch out - too much beating makes it grainy.

When I was little in France, my aunt made this every Christmas Eve. She always told me that taking your time with the whipping and rolling makes the prettiest swirl inside.
Smooth Ganache Making
Warm cream until tiny bubbles form, then pour it over your chopped chocolate. Wait 5 minutes before you stir. Let it cool until it gets thick but can still spread easily.
Pretty Finishing Touches
Make the outside look like tree bark using a fork or special tool. Add some cocoa powder to make it look weathered. Put sugared cranberries and rosemary sprigs on top for a woodsy look.

After making this treat for many holiday seasons, I've learned that getting the temps and timing right for each part is key. This Yule Log has turned into the dessert my family asks for most at Christmas, bringing both old-fashioned charm and fancy looks to our holiday meals.
Frequently Asked Questions
- → Why should I roll the cake when it's hot?
- Rolling the warm cake trains it to curl without breaking later when you add filling. It basically teaches the cake to remember the rolled shape.
- → Is it possible to prepare this dessert beforehand?
- You can fix up the cake 2 days early, but wait to put on the sugared garnishes until right before you serve it so they stay crisp and pretty.
- → What causes my ganache to look gritty?
- Gritty ganache usually means it got too hot. Just warm the cream until bubbles form at the edges, then let it sit with the chocolate chunks before you stir them together.
- → Can this cake go in the freezer?
- You bet! Once it's filled and rolled, wrap it tight in plastic and freeze for up to a month. Just don't add the ganache until after thawing.
- → How do I make realistic wood patterns?
- Drag a fork in long strokes through the ganache, then make swirly circles for knots. Keep going in the same direction for the most natural wood look.
