Preheat oven to 350 degrees. Coat a 8x8 baking dish with oil of your choice or cooking spray, set aside.
Add chickpeas, peanut butter, maple syrup, vanilla, salt, baking powder, baking soda and cacao powder to a food processor. Blend until creamy. (this may take a few minutes!)
Transfer mixture to a bowl and fold in ⅓ cup chopped walnuts.
Evenly spread mixture into a greased 8x8 baking dish, top with ¼ cup chopped walnuts and ¼ cup mini-chocolate chips and cook for 20-25 minutes.
Brownies are done when a tooth pick inserted comes out clean.
Cool, cut and enjoy :)
Notes
Top with a little whipped coconut cream and you have a decadent dessert :)Like I said before, no one needs to know they were made with chickpeas :)
