Instructions

1. Preheat the oven to 180 °C and line a baking sheet with parchment paper.
2. Mix the flour, cocoa, cinnamon and salt in a bowl.
3. Cut the cold butter into pieces and rub it into the flour with your fingertips until you get a sandy texture.
4. Add the icing sugar, chopped walnuts, egg yolks and vanilla. Knead quickly until you have a smooth dough.
5. Shape small irregular balls the size of a walnut, giving them a pebble shape, and place them on the tray.
6. Bake for 12 minutes, until firm to the touch but still slightly matt.
7. Let them cool completely on a rack, as the biscuits harden as they cool.
8. Once cold, dip half of each biscuit into the melted chocolate and let it set on parchment paper.
