Preheat the oven to 350°F (175°C) and line an 8x8-inch square baking pan with parchment paper.
Place the chickpeas, peanut butter, maple syrup, vanilla, salt, baking powder, and baking soda into a high-speed food processor.
Process the mixture until completely smooth and creamy, stopping to scrape down the sides as needed.
Remove the blade and fold in 1/3 cup of chocolate chips manually.
Transfer the batter into the prepared pan and smooth the top with a spatula.
Sprinkle additional chocolate chips over the surface if desired.
Bake for 20 to 25 minutes until the edges are golden brown and a toothpick inserted into the center comes out clean.
Allow the blondies to cool completely in the pan for at least 30 minutes to ensure they set properly before slicing.
