1. Preheat the oven to 350°F. Combine the chocolate and butter in a small microwave-safe dish and microwave in 30-second intervals, stirring after each, until smooth, about 2 minutes. Set aside to cool slightly.
2. Whisk the almond flour, all-purpose flour, ginger, cinnamon, cloves, nutmeg, baking powder and salt together in a large bowl. Beat the eggs and brown sugar in another large bowl with an electric mixer until pale and fluffy. Add the chocolate mixture and beat until combined. Add the flour mixture and mix on low speed until incorporated. Refrigerate the mixture until firm, at least 1 hour.
3. Place the granulated sugar in a shallow bowl and the powdered sugar in another shallow bowl. Form the dough into balls ¾-inch in diameter and roll them first in the granulated sugar and then in the powdered sugar, until generously coated like a powdered doughnut. Place on 2 non-stick baking sheets about 2 inches apart and bake for 8 to 10 minutes.
4. Let the cookies cool for a couple of minutes on the baking sheets before transferring them to a cooling rack.
