Preheat your oven to 340°F (170°C). Line a large baking sheet with parchment paper.
Put 3 cups almond flour, ⅔ cup powdered sugar, 1 large egg white, 1 tablespoon honey and the grated zest of 1 orange into a bowl.
Stir with a spoon, then use your hand to gently squeeze and pinch the mixture until it comes together into one ball.
If it still won’t stick after about a minute, add a tiny bit more egg white.
Sprinkle 3 tablespoons powdered sugar onto a plate. Break off pieces of dough and roll them into small balls (you should get 15 balls—about 1 ounce or 30 g each).
Roll each ball in the powdered sugar.
Place balls on the baking sheet, then gently press your thumb into the center so the edges crack a little.
Bake at 340°F (170°C) for 12 minutes. Let them cool before eating.
