In a small bowl, mix almond flour, granulated white sugar, egg white, finely grated orange zest, and orange extract. Stir until combined. Cover with plastic wrap and refrigerate for 2 hours.
Preheat the oven to 350 degrees F. Spray a baking sheet with nonstick spray.
Spoon out even tablespoonfuls of dough and roll into balls. Place on the prepared baking sheet. You should be able to make 15 little balls of dough.
Bake for 10 to 12 minutes, or until the balls of dough are firm and are golden underneath.
Remove from the oven and let cool for a few minutes, then give them a roll in powdered sugar.
