Preheat the oven to 350°F (180°C). Line a 9-inch x 9-inch brownie pan with parchment paper. Set aside.
Open the can of chickpeas, rinse, drain and dry/rub the chickpeas in a clean towel to remove all the water or moisture. This is very important, or the blondies will be fragile and too moist.
Place the chickpea in the bowl of a food processor and add peanut butter, maple syrup, vanilla, baking soda, baking powder, and salt.
Blend on high speed for 1 minute or until smooth, and no big lumps are left.
Add in almond flour and process again at high speed for 15-30 seconds to blend evenly.
Remove the food processor blade and stir in chocolate chips. I recommend keeping 3 tablespoons on the side and sprinkling them later on top of the blondies. This prevents adding too many chocolate chips in the batter that will melt and turn your blondies into brownies.
Spread the blondie batter evenly onto the prepared baking pan and sprinkle the chocolate chips you set aside on top.
Bake 20 - 30 minutes or until golden and crusty on top. If your pan is wider, it will cook way faster. On the other hand, if your pan is smaller, the blondies are thicker, and it may take more than 30 minutes to set. Always insert a pick in the center of the blondie to check baking. If it comes out clean with little crumbs, it is ready.
Cool 10 minutes in the pan to firm up the blondies. Don't skip this, or they will break. Then gently loosen the sides with a knife and lift the pieces of parchment paper to easily release the blondies from the pan and transfer it onto a cooling rack. Careful, the blondies will still be soft and fragile. If you feel it is too soft or moist, wait for 10 more minutes before transferring it onto the cooling rack. This prevents the blondies from breaking.
Cool for at least 1 hour before slicing into 1 bar, or they can be fragile. After 1 hour, you can pop the blondies in the fridge for 1 hour. It will add an extra fudgy texture and make it easier to slice.
Store up to 5 days in the fridge in an airtight container.
Nut-free option: Replace the peanut butter with sunflower seed butter and almond flour with oat flour.Almond flour swap: Use the same amount of oat flour or all-purpose flour. Note that the blondies are fudgier with almond flour.Maple syrup swap: Use the same amount of agave syrup, rice syrup, or date syrup.
