Preheat oven to 350 degrees F.

Grind your old-fashioned oats and flaxseed in a food processor until powdery. Alternatively, you can use a mortar and pestle if you have one.

Add all ingredients to a bowl and mix well.

Scoop dough with a teaspoon and roll into small balls, place on a baking sheet lined with parchment paper.

Gently flatten the tops of the cookies using a fork or, as I do a meat tenderizer.

Bake for 12 minutes, or until bottoms of cookies have browned a little.

Transfer cookies to a wire rack and let cool completely.
