Preheat the oven to 350 F degrees. Line an 8 by 8-inch baking pan with parchment paper.
Combine the black beans, dates, jam, and vanilla in a food processor.
Blend until smooth.
Add the flour, cocoa powder, salt, and mint extract and blend again.
Pour into the prepared pan and smooth the top with moist hands.
Bake for 30 minutes. While the brownies are baking, crush your candy canes into small pieces, not dust.
Remove from the oven and top with crushed candy cane pieces. When completely cool, use the parchment paper to lift the brownies out of the pan.
Cut into 16 squares.
Store brownies in a covered container for up to 1 week.
