Walnut Cookies

Preheat the oven to 160 °C fan (or 180 °C conventional) and line a baking sheet with parchment paper.

Roughly chop the walnuts and set aside.

Cream the butter with the white and brown sugar until the mixture lightens and the sugar has mostly dissolved.

Beat in the egg and vanilla sugar until everything is evenly combined.

Sift the flour into a second bowl and mix thoroughly with the baking powder and cocoa powder.

Add the flour mixture to the butter mixture in portions and briefly stir into a smooth dough.

Fold in the chopped walnuts at the end.

Use two teaspoons to scoop small portions of dough and place them with enough space on the baking sheet.

Bake in the preheated oven for 10–12 minutes.

Remove the sheet, let the cookies rest on it for 5 minutes, then transfer to a cooling rack to cool completely.
