Preheat the oven to 180 degrees (355 F) top and bottom heat.
In a small blender, blend 1 cup of rolled oats with 2 tablespoons of linseed until both are finely ground.
Now place the ground oats and linseed in a bowl, with the other dry ingredients (the cup of whole oats, raisins, baking powder, cinnamon, salt, vanilla), and mix with a spoon.
Blend the milk, dates, and almond butter in the blender jug from before until creamy (and be sure to taste this delicious mixture!).
Pour the milk-date-almond cream into the bowl with the dry ingredients and stir with a spoon.
Now form small balls (about the size of a golf ball) and place them evenly on a baking tray lined with baking paper (three rows of four). I form the balls by hand and have a bowl of water ready to moisten my hands in between (otherwise it gets too sticky).
Flatten the dough balls with a fork to a thickness of approx. 1 cm, which is a bit less than 1/2 inch (check out the photos above). Have a small bowl or cup of water ready and dip the fork from time to time, otherwise, it will stick to the cookie.
Bake on a medium heat for approx. 18 minutes, until the edges are just starting to brown. The cookies will still be soft on the inside.
Open the oven door and leave the cookies to cool for approx. 20 minutes.
