Puree black beans in food processor until smooth.

In a separate bowl, combine cocoa powder, maple syrup, baking powder, and salt.
Add the dry ingredients to the wets and then stir in chocolate chips.
Grease an 8×8 or 9×9 inch pan then line with parchment paper.
Pour in batter and bake for 30 to 40 minutes, or until the edges are visibly cooked. Remove brownies from oven when done and let cool for 5-10 minutes.
While brownies are baking, melt almond butter and maple syrup on low heat in small saucepan until mixed evenly, about 3-4 minutes. Remove from heat for 1 minute to thicken.
When ready, drizzle almond butter syrup over brownies, dust some powdered sugar on top, and serve warm!
