In a medium bowl, whisk together the flour, baking powder and salt. Set aside. In a small bowl, mix the sugar and orange zest. Rub together with your fingers until zest is throughout the sugar. The sugar will become moist from the oils being released.

Using a mixer, cream the butter and orange zested sugar. Add egg and orange juice. Slowly add the dry ingredients until well incorporated. At this point you can chill for an hour or so or overnight. Scoop onto a cookie sheet lined with parchment paper and roll into smooth round balls. Bake at 350°F for about 10 to 12 minutes or until very lightly golden on the bottoms. Don’t over bake or they will be a bit to dry and lose the perfect texture.

Mix the confectioners’ sugar, orange zest and enough orange juice to get a glaze consistency and blend until smooth and creamy. Pour glaze over the tops of the cookies and let set.

Feel free to mix up the citruses. Use lemons or limes rather than oranges, or use some of every.
