Preheat the oven to 350°F. Spray an 8- x 8-inch baking pan with nonstick cooking spray.
Place half of the chocolate chips in a small bowl. Microwave for 30 seconds, stir, and repeat until the chips have melted.
Using a food processor, blend the beans and oil together.
Add the eggs, cocoa powder, sugar, vanilla, and melted chocolate chips to the food processor, then blend until the mixture is smooth.
In a large bowl, whisk together the flour, chili powder, cinnamon, baking powder, and salt.
Pour the mixture from the food processor into the bowl and stir with a wooden spoon until well-combined.
Fold in the remaining chocolate chips, then pour the batter into the prepared pan.
Place in the oven and bake for about 25 minutes. Once the brownies start to pull away from the sides of the pan and are still shiny in the middle, they’re finished baking.
Let your brownies cool in the pan, then cut into 16 squares.
