Orange Crinkle Cookies

Wash the organic orange thoroughly, rub it dry, and finely grate the zest. Squeeze the juice from one half.

Sift the flour with the baking cocoa, baking powder, and 70 g of powdered sugar into a bowl. Add the whisked egg, soft butter, orange zest, and 1 tsp of orange juice. Knead everything into a smooth, slightly sticky dough. Wrap the dough in cling film and let it rest in the refrigerator for at least 2 hours.

Preheat the oven to 200 °C top/bottom heat. Line a baking sheet with baking paper. Sift the remaining powdered sugar into a deep plate.
