Heat the oven to 350°.
Blend the chickpeas, nut butter, maple syrup (or coconut nectar), coconut oil, and vanilla in a food processor.
Add the flour, cocoa powder, baking powder, baking soda, and salt. Blend, scraping the sides of the container as necessary.
Once the batter is creamy, transfer it to a mixing bowl and stir in the chocolate chips.
Grease an 8x8 pan and pour in the batter. Bake for 20-30 minutes.
