Preheat the oven to 350°F and line a rimmed baking sheets with parchment or silicone liners.
In a medium bowl, whisk together the almond flour, coconut flour, ginger, cinnamon, bakingsoda, and salt.
In a large bowl, beat together the butter and erythritol until smooth. Beat in the egg, molasses, vanilla, and stevia until well combined.
Add the almond flour mixture and continue to beat until the dough comes together.
Chill dough for 10 minutes, then roll into 1 inch balls and place a few inches apart on the prepared baking sheet, flatten each cookie down just a bit with your finger tips so they look like thick discs.
Bake for 8-12 minutes to until set through and crackled over the top (they will also smell delicious).
Remove and let cool completely on the pan. Transfer to a plate or an airtight container and repeat until all cookies are done.
Note: they will be very soft so do not handle until fully cooled. The longer they sit out the firmer they will become!
