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.**
Store in an airtight container in the refrigerator up to one week.

Notes
I do not recommend substituting garbanzo bean flour for the chickpeas as the flavor is very bean-y.
To make the drizzle, melt 1/4 cup chocolate chips with 1 teaspoon coconut oil. You can also drizzle 1-2 tablespoons of melted nut butter over the chocolate drizzle. Drizzle not included in the nutritional value.
