What Is a Brownie Yule Log?

A brownie yule log is a festive twist on the classic Christmas dessert. Instead of a light sponge, this version uses a thin-baked brownie sheet that’s rolled with a creamy filling and decorated to resemble a traditional log.

How It Differs From a Traditional Yule Log

• Texture: Rich and fudgy rather than light and airy
• Flavour: Deep chocolate brownie flavour
• Vibe: Modern, indulgent, and very crowd-pleasing

It’s ideal if you’re looking for the best brownie yule log recipe with maximum impact and minimal faff.

What’s the Difference Between a Yule Log and a Roulade?

They’re closely related. A roulade is the technique (rolling a baked sheet with filling), while a yule log is the festive presentation – decorated to look like a log and traditionally served at Christmas.

How to Make a Brownie Yule Log

1. Prep Your Tin

Preheat the oven to 180°C (160°C fan). Line your tin with baking parchment, leaving an overhang.

2. Melt Chocolate and Butter

Gently melt together until smooth - you can achieve this easily in the microwave in short bursts or in a large heatproof bowl over a pan of boiling water. Set aside to cool slightly.

3. Whisk Eggs & Sugar

Whisk your St. Ewe Original Large eggs and both sugars until pale, thick, and fluffy. This step adds lightness and structure.

4. Combine Wet Ingredients

Slowly whisk the melted chocolate mixture into the eggs & sugar.

5. Add Dry Ingredients

Sift in flour, cocoa powder, and salt. Fold gently until just combined.

6. Bake the Brownie Sheet

Pour into the tin and spread evenly. Bake for 12–15 minutes – it should be set but still soft.

7. Prepare for Rolling

Lay a clean tea towel on the worktop and dust lightly with cocoa powder.

8. Roll While Warm

Turn the brownie out onto the towel, peel off parchment, and gently roll from the short end. Leave to cool rolled up.

9. Make the Filling

Whip or prepare your chosen filling until smooth and spreadable.

10. Unroll & Fill

Carefully unroll the brownie and spread filling evenly, leaving a small border.

11. Roll Up Again

Re-roll gently but firmly. Don’t panic about cracks – they add character.

12. Decorate!

Cover with ganache or frosting. Use a fork to create a bark effect and dust with icing sugar.

13. Chill & Serve

Chill for at least 30 minutes before slicing. Enjoy!
