1. Preheat the oven to 350°F (180°F). Line a baking sheet with baking parchment and set aside. Mix the chia and water in a small bowl and let sit for about 5 minutes.

2. Add the peanut butter, brown sugar, cocoa powder, baking soda, vanilla extract, and the chia mixture to a bowl and mix everything until well combined. Divide into six portions and shape each dough portion into a ball, flatten it, and place them on the prepared baking sheet. Sprinkle with some chopped peanuts and bake for about 10-11 minutes – the edges should have set, but the centers of the cookies are still soft. Take out of the oven and let cool down on the baking sheet for some time, then transfer to a wire rack and let cool down completely.
