In a big bowl, crumble the cake: add half the brandy and the chopped nuts or almonds, and set aside.
In a saucepan, prepare a syrup by simmering the water and the sugar with a cinnamon stick: after about 5 minutes, the syrup starts boiling.
Now it's time to turn off the heat.
Remove the cinnamon and add half the brandy and the chocolate: stir until it melts.
Add the chocolate syrup to the cake: mix very well with a spatula and then knead until it has a good consistency.
Place the cake and chocolate mixture on a piece of parchment paper and make a roll (cylinder): place on cling film and store in the freezer for at least two hours.
Melt the chocolate for the coating in a bain-marie: remove the transparent film and cut the cylinder into 2 cm wide circles that you will cut in half to create crescents.
Using a special tool if you have it, or simply two forks, dip each crescent into the melted chocolate and place on a cooling rack or on parchment paper (take to the fridge if you’re doing this in summer).
Serve them once they’re cool and dried with a good cup of coffee.
