Preheat oven to 180°C/350°F.
Mix the coconut milk, flaxseed and almonds in a bowl.
Mix the flours, cocoa powder, bicarbonate of soda, protein powder, dark chocolate and stevia in a bowl. Add the oils, stevia mixture and vanilla extract to the coconut milk mixture. Stir well. Leave to stand for 10 minutes.
Pour the wet mixture into the dry mixture and stir well. Add a drop of water if needed. The consistency should be of a thick paste.
Line several trays with baking paper. Roll small amounts of the mixture into balls. Press gently into disc shapes (maximum 15mm thick) onto the baking paper. Allow some space between the cookies, as they will spread a little during baking. Sprinkle a little extra stevia on top of each cookie, and gently press it into the dough. Bake for 7-10 minutes. Transfer to a wire rack to cool.
