Nut Cookies

For the dough, mix the flour, cocoa powder, cinnamon and sugar. Chop the butter into small pieces. Add the egg and butter to the flour mixture and knead into a smooth dough. Wrap the dough in plastic and chill for about 20 minutes. Roll out on a floured surface and place on a lined baking sheet.

Preheat the oven to 200°C (approximately 400°F). For the topping, heat the butter, sugar, vanilla sugar and 6 tablespoons of water until golden brown. Remove from the heat, stir in the nuts and spread the mixture on the dough.
