Add black beans, dates, almond butter, cocoa powder, vanilla extract, maple syrup, baking powder, salt, and non-dairy milk to a food processor.
Pulse a few times, then blend until smooth, scraping down the sides as needed.
Stir in chocolate chips.
Line an 8x8 inch pan with parchment paper, optionally spritzing with oil spray to hold it in place.
Spread the batter evenly into the prepared pan.
Add optional toppings like chopped nuts and chocolate chips, pressing them slightly into the batter.
Sprinkle with flaky sea salt, if desired.
Bake in a preheated oven at 350°F (180°C) for 35-45 minutes, or until set.
Allow to cool completely before slicing into 16 pieces.
