Preheat your oven to 350°F (175°C) and grease an 8x8-inch baking pan or line it with parchment paper.
In a food processor, combine the drained chickpeas, peanut butter, maple syrup, cocoa powder, vanilla extract, baking powder, and salt. Blend until smooth and creamy.
Stir in the dark chocolate chips by hand until evenly distributed.
Pour the brownie mixture into the prepared baking pan and spread it evenly. Bake for 25-30 minutes until the edges are firm.
Allow the brownies to cool in the pan for at least 10 minutes before cutting into squares.
