In a medium bowl combine the butter, coconut sugar, and vanilla extract using a stand mixer or hand mixer until fluffy. Add flour and mix until a thick dough is formed.

Finely chop the dark chocolate and pecans, add them to the bowl with the dough. Using spoon or spatula mix everything until incorporated.

Divide prepared dough in half. Place half dough on a piece of plastic wrap and roll into a log (repeat the same with the other half). Once formed, wrap them with the plastic wrap and chill in the fridge for 30 minutes.

Remove the plastic wrap and cut your dough into slices. Place them on the baking tray lined with baking paper or silicone baking mate. Bake your cookies for about 12-15 minutes.
