Preheat oven to 350 degrees Fahrenheit and line a ¼ sheet pan with parchment paper (or grease the pan if you don't have parchment paper)
Add cooked black beans to blender or food processor.
Add cane syrup, oil, and vanilla and blend/process for about 60 seconds until well combined.
Add eggs and blend again for about 30 seconds until well incorporated and very few black flecks from the beans remain.
Add dry ingredients (baking powder, cocoa powder, salt, brown sugar) and blend again for about 20 seconds until smooth.
Pour batter into prepared baking pan, add 1/4 cup chocolate chips, and gently mix in with a wooden spoon.
Bake in the preheated oven for 30-40 minutes, removing them when the center appears firm, and the edges aren't burnt. You don't want gooey brownies for this so keep them in longer if you're unsure if they're done.
Remove from oven and allow to cool for 15-20 minutes.
Once cooled, small scooper or a small spoon, scoop out balls of brownie and roll into a ball about the size of a fresh cherry and place on a parchment lined baking sheet.
Once all the balls have been formed, freeze them for about 15 mins until hardened and cold.
Melt chocolate of your choice in the microwave or using a double boiler and dip each ball into the chocolate just long enough to coat it in chocolate and return to the baking sheet.
Once all the balls have been dipped in chocolate, sprinkle with a garnish of your choice and freeze again for about 10 minutes.
