Brookie Log (Cookie/Brownie)


Brookie Log (Cookie/Brownie)

10 December 2025

Difficulty: toque toque toque

Penultimate log of this year 2025, and not the least since it is probably one of the most indulgent: a brookie-style log, with chocolate mousse, brownie, cookie dough, cookie, and a wonderfully creamy vanilla namelaka. Ultimately, no complicated preparation but a lot of indulgence to end your Christmas meals well!

Preparation time: 1h10 + 20 minutes of baking + freezing / defrosting time
For a 28cm log:

 Vanilla namelaka:
 
100g of whole milk
 1 vanilla pod
 2g of gelatin
 170g of white chocolate
 200g of heavy cream
 
 Soak the gelatin in cold water.
 Heat the milk with the seeds from the vanilla pod, then add the rehydrated gelatin (and squeezed if you are using sheets). Pour the hot liquid over the previously melted white chocolate, then blend with an immersion blender to obtain a smooth and shiny ganache. Finally, add the cold cream, then blend again. Cover with plastic wrap and let crystallize in the refrigerator for at least 6 hours.

 Finishing touches:

 300g of dark chocolate
 60g of neutral oil
 A bit of white chocolate (optional)
 
 Melt the dark chocolate, then add the neutral oil.
 Unmold the frozen log, then place it on a rack. Pour the glaze over it, then if you want, add a bit of melted white chocolate to "draw" cookies. Place the log on your serving platter, in the refrigerator for at least 4 hours to defrost before enjoying!
