Preheat your oven to 350°F (175°C) and line an 8x8 inch baking pan with parchment paper.
In a food processor, blend the black beans until smooth. Make sure there are no chunks left.
Add the eggs, peanut butter, honey (or maple syrup), unsweetened cocoa powder, vanilla extract, baking powder, and salt to the blended black beans. Process until smooth and well combined.
Gently fold in the chocolate chips with a spatula until evenly dispersed in the batter.
Pour the mixture into the prepared baking pan and spread it out evenly.
Bake for 25-30 minutes, or until the edges are firm and a toothpick inserted into the center comes out mostly clean (a few moist crumbs are okay).
Allow the brownies to cool in the pan for at least 15 minutes before lifting them out and cutting them into squares.
Notes
Serve warm topped with a dollop of Greek yogurt or a scoop of protein-packed ice cream for an extra treat!
