Chocolate-Dipped Orange Cookies

In a bowl, mix flour, powdered sugar, baking powder, orange zest, butter and egg until a smooth dough forms.

Wrap the dough in plastic wrap, roll into a log and flatten slightly.

Refrigerate the wrapped dough for about 1 hour.

Cut the chilled log into 0.5–1 cm thick round slices using a sharp knife.

Bake in a preheated oven at 175°C (350°F) for 12 minutes, until edges are just golden.

Melt the dark chocolate over a double boiler, dip half of each cookie, then let set.
