Start by roasting the walnuts and hazelnuts until fragrant. Let them cool and chop into medium sized pieces.
In a food processor finely crush all the biscuits.
In a large bowl, add the crushed biscuits, chopped nuts, cocoa powder, and whole candied cherries. Combine together.
Add the condensed milk and the vermouth, if desired. With your hands mix everything well together until you achieve a sticky mixture.
Roll this mixture in a cylindrical shape and set aside for now.
Melt the chocolate and cover the log shaped dessert completely. To get the trunk texture, you can simply pass through the melted chocolate with a fork to get all those ridges.
Let the chocolate harden before slicing through it and don’t forget to add your decorations with a sprinkle of icing sugar.
Ideally, the Christmas log doesn’t get stored in the fridge as this will make it dry.
