Preheat oven 350° F. Prepare an 8x8 baking pan by spraying it with nonstick cooking spray.
To a blender or food processor, add all ingredients except chocolate chips. Process on high until creamy and smooth. Fold chocolate chips into the batter by hand.
Bake at 350° F 20-25 minutes until a toothpick can be inserted clean. Cool in the pan 30 minutes prior to slicing into 16 bars.
Optionally drizzle the tops of he bars with melted chocolate and extra nut butter.
Notes
Drain, rinse, and pat the chickpeas dry to avoid adding excess moisture to the chickpea blondie batter.
Run a knife under hot water and wipe it clean after every cut to make the cuts clean.
Place cooled blondies in the refrigerator for an hour to give them a more fudgy texture.
If you replace peanut butter with sunflower butter, be aware it will turn the blondies green due to the chemical reaction with baking soda.
Store leftovers in an airtight container in the refrigerator up to one week.
