Preheat your oven to 350 degrees Fahrenheit. Grease an 8×8 baking pan or line it with parchment paper to prevent sticking.

In a good food processor, blend all the ingredients (except the chocolate chips) until very smooth. If you don't have a food processor, an electric mixer and a large mixing bowl will work too. Just ensure to blend the beans very well.

Mix the chocolate chips into the blondie batter using a wooden spoon. You can also add some chocolate chips on top for extra gooeyness.

Scoop the batter into the prepared baking pan. I used a square baking tin. Bake for 30 minutes. The blondies will look a little undercooked when you take them out, but they will firm up as they cool to a golden brown once they reach room temperature.

Allow the blondies to cool in the baking pan. Once cooled, you can cut them into squares. Store the blondies in an airtight container to keep them fresh.
