Preheat the oven to 350 degrees F.
Add the first 4 ingredients (egg through vanilla extract) to a mixing bowl and whisk well (note: you can also use a stand mixer). In a separate bowl, stir together the next 4 ingredients (almond flour through baking soda).
Pour the dry ingredients into the bowl with the wet and stir until combined. Fold in the chopped dark chocolate.
Drop cookie dough onto a large baking sheet in the same shape you want the cookies (the cookies will not rise or spread while they bake. I like to bake the dough in balls and then gently press them into a disc/cookie shape once they are finished baking).
Bake for 10 to 12 minutes, or until cookies reach desired level of done-ness.
I like using a Paleo Chocolate Bar, but you can use any type of chocolate bar or chocolate chips.
