Preheat oven to 350°. In a blender add chickpeas, bananas, oats, salt, egg, and vanilla extract and blend until it forms a smooth consistency.
In a small pot on low heat add chocolate chips, cocoa powder, and nut milk. Cook until powder is blended in and chocolate chips are melted. Whisk slowly, often, to make sure the chocolate doesn't burn.
Remove from heat and pour in the chickpea mixture and stir until well combined.
Spray a 9 x 9 inch baking dish with cooking spray and add the brownies batter.
Bake for 25 to 30 minutes or until cooked through.
Let cool completely and then cut into squares before serving!
