Preheat your oven to 350°F (175°C) and line a baking tray with parchment paper.
In a small bowl, cover the dates with hot water. Let soak for 5-10 minutes.
Rinse and drain the black beans well.
Add the beans, soaked dates, peanut butter, almond milk, cocoa powder, and baking powder to a blender. Blend until completely smooth. The mixture will be quite thick, you may need to use a tamper to scrape down the sides of the blender. You can also add another tablespoon of milk if needed.
Either in the blender or in a separate bowl, add and stir in the chocolate chips until combined.
Scoop small portions, about 1 tablespoon of batter, onto the tray and gently flatten into cookie shapes.
Bake for 12-14 minutes, until the tops are just starting to turn golden brown.
Let cool for a few minutes before serving.
