100g icing sugar
1 tsp baking powder
1/2 an orange's juice
Zests of one orange
Mix the sugar, the butter and the egg until it becomes homogeneous.
Add the flour, baking powder, the juice and the zests. Knead together.
Transfer the crinkle dough to a sheet of baking paper and wrap it with it. Reserve in the fridge for 60 minutes.
Preheat your oven to 180°C/ 356°F
Shape cookie balls with your dough, roll then in icing sugar, and reusing your initial sheet of baking paper, line an oven tray for your crinkles.
Bake your crinkles for 15 minutes. They may still be very soft when you take them out of the oven but do not worry, let them cool down on a rack and they will reach the desired texture.
