Whisk oats, baking powder, cinnamon and vanilla extract together. Mix cashew butter, agave syrup separately and add your chia egg together until it is smooth. Then add the chocolate powder, dried blueberries and walnuts. Mix everything well again.
Pour the dry ingredients to the wet ingredients, then mix on low until combined.
Afterwards I used my hands to knead the dough properly. Now let the dough rest in the fridge for about 30 minutes.
I formed the cookies with an ice-cream scoop and put them on the baking paper.
Now bake the oat cookies in the oven for about 10 minutes at 180°.
