1.
Combine the rolled oats, flour, baking powder and salt in a large mixing bowl.
2.
Mix the ground flaxseeds with the water in a small bowl and let swell for at least 10 minutes until the consistency is thick and viscous like beaten egg.
3.
Finely chop the dates. Place in a separate bowl with tahini and the orange juice and zest. Add the flaxseed mixture and mix everything well.
4.
Add the liquids to the dry ingredients and combine with a spatula. If the mixture is too dry, add a little water or oat milk. The mixture should be relatively firm. Fold in the chopped chocolate.
5.
Preheat the oven to 180°C. Line a baking sheet with parchment paper. Scoop dough with a tablespoon, shape into balls, place on the sheet and flatten.
6.
Bake at 180°C for about 15–20 minutes until the cookies get golden-brown edges. Let cool well and store in an airtight container.
