Preheat oven to 350°F and prepare a baking pan with parchment paper.
In a food processor, blend the chickpeas, nut butter, maple syrup, baking powder & soda, salt (and peanut butter powder if you have it).
Add in the almond flour and blend again until combined.
Stir in the chocolate chips and transfer to the prepared baking dish.
Sprinkle some more chocolate on top and place in the oven for about 20 minutes (more or less time depending on the size of the baking pan).
Let cool completely before cutting!
