Preheat your oven to 350° F (approximately 177 ° C or gas number 4). Line two baking trays with parchment paper.
Microwave ¾ cup chocolate chips in small intervals until mostly melted, then stir. Reserve ½ cup of chocolate chips for the dough. If the chocolate is still solid, microwave for an additional 10-20 seconds. Allow the melted chocolate to cool slightly before using.
In a bowl, combine unsweetened cocoa powder, almond flour, baking powder, grated orange peel, salt, and ¾ cup sugar-free confectioner's sweetener (reserve the remaining ½ cup for coating).
In a bowl, beat eggs until light and fluffy. Stir in vanilla and melted butter, until combined.
Carefully combine the dry and wet ingredients then add the melted chocolate chips.
Stir in the coffee and chocolate chips. The dough should be firm, but not sticky. If it's too sticky, add cocoa powder. If it's too firm, add melted butter or coconut oil.
Wrap the bowl in saran wrap and allow the dough to chill in the refrigerator for at least 1 hour.
Using an ice-cream scoop, scoop balls of dough and roll them into balls by hand. Place the dough balls on the baking sheets, spacing them 2 inches (5cm) apart.
Bake for about 10-15 minutes at 350° F (approximately 177 ° C or gas number 4) until slightly cracked peaks form.
Remove the cookies from the oven and let them cool on the baking sheet for 10 minutes. Transfer them to a cooling rack. If the cookies do not form properly, you can gently press them with a spatula while they are still warm. (see notes below).
Roll the cookies in the sugar-free confectioners sweetener, while they are still warm. Let the cookies cool completely before serving.
