Prepare 1/2 flax egg by mixing 1/2 tablespoon of ground flax seeds with 1 1/2 tablespoons of cold water, let stand for 10 minutes.

In a medium bowl, combine all 'wet' ingredients (up to the flour) and mix with a hand mixer until smooth and well combined.

In another bowl, mix the flour, baking powder and salt before adding it to the wet ingredients. Mix well until you have a soft dough. Add more chopped peanuts if you like.

Chill the dough for 30 minutes.

Preheat oven to 350F (180C)

Divide dough into 6 equal pieces and roll them into a ball. Slightly press some chopped peanuts into the dough and flatten the balls at the same time.

Bake for 11 to 12 minutes.The tops will be soft but will set as the cookies cool. If the tops and edges both are too soft, bake for an extra minute.

Cool the cookies on the sheet for 10 minutes, before transfer them on a wire rack to cool completely.
