Ingredients:
1 (15-ounce) can no-salt-added black beans, drained and rinsed  
3 large eggs  
1/3 cup melted butter, more for the baking dish  
1/4 cup cocoa powder  
1/8 teaspoon salt  
2 teaspoon gluten-free vanilla extract  
1/2 cup plus 2 tablespoons cane sugar  
1/2 cup gluten-free semi-sweet chocolate chips  
1/3 cup finely chopped walnuts  

Method:
Preheat oven to 350°F.  
 
Butter an 8-inch baking pan. Place the black beans, eggs, melted butter, cocoa powder, salt, vanilla, and sugar in the bowl of a food processor and blend until smooth. Remove the blade and carefully stir in the chocolate chips and walnuts. Transfer mixture to the prepared pan. Bake the brownies for 30 to 35 minutes, or until just set in the center. Cool before cutting into squares.
