Add the almond flour, baking powder, vanilla, egg, ground ginger, cinnamon, nutmeg, brown sweetener and sugar free honey into a mixing bowl, and beat until a solid dough forms.
Wrap the dough in plastic wrap, and chill in the fridge for 2 hours.
Preheat the oven to 350 degrees.
Roll the chilled dough out between two pieces of parchment paper until it is about ¼ of an inch thick.
Cut the dough with a gingerbread man cookie cutter.
Place the cut out gingerbread men onto a parchment lined baking sheet.
Bake for 10-12 minutes until lightly browned.
Let the cookies cool to room temperature.
Add the powdered sweetener to a bowl, and whisk in heavy whipping cream until a thick icing has formed.
Pipe the icing onto the cookies in any decoration you may like.
Add holiday sprinkles before serving if desired.
