Set your oven to 350°F (175°C) to preheat.

In a mixing bowl, beat the unsalted butter and icing sugar together until light and fluffy, about 3-5 minutes.

Mix in the finely grated orange peel.

In a separate bowl, whisk together all-purpose flour, cornflour, cinnamon powder, and salt.

Gradually add the dry ingredients to the wet mixture, folding gently until a smooth dough forms.

Scoop tablespoon-sized portions of the dough, roll into balls, and place them on a baking tray lined with parchment paper. Flatten slightly.

Place the tray in the preheated oven and bake for 12-15 minutes until the edges are lightly golden.

Remove cookies from the oven and let them cool on the baking sheet for 5 minutes before transferring to a wire rack.
