In a large mixing bowl, whisk together the almond flour and cocoa powder.
Pour in the honey, coconut oil, egg and vanilla extract and blend will with a wooden spoon.
Using your hands, form walnut sized balls of dough. Flatten them on the cookie sheet. They will not spread or rise during baking, so the shape you create is the shape you end up with after baking. The dough can be a little sticky...
Bake at 350 F. for about 15-20 minutes, or until completely cooked through.
While the cookies bake, mix all the filling ingredients together in a food processor or using an immersion blender.
Allow the cookies to cool after baking and then create your sandwiches using the filling.
NOTE: You can adjust the thickness of the filling by using more or less cocoa powder. Just keep in mind that as it sits, it will thicken more. It takes a few minutes for the cocoa powder to really absorb the liquid.
