Black Bean and Avocado Brownies

1. Preheat the oven to 350 degrees F (175 degrees C). Coat a 9-inch square baking pan with cooking spray.

2. Whisk eggs, mashed avocado, and vanilla extract together in a large bowl. Add black beans; purée with an immersion blender until beans are mashed and batter is smooth.

3. Combine brown sugar and cocoa powder in a separate bowl; add to batter. Mix by hand with a wooden spoon until completely combined; stir in chocolate chips. Pour batter into the prepared pan.

4. Bake in the preheated oven until a knife inserted into the center comes out clean, 25 to 30 minutes. Cool completely before cutting and serving.

Cook's Note:

Instead of avocado you can use 3 tablespoons vegetable oil.
