Place a piece of parchment paper on a cookie sheet.
Wash the banana, then cut the ends off and slice the banana down the middle like a hot dog bun.
Place the 2 banana halves on the parchment paper.
Drizzle the pure maple syrup on the banana halves, use your finger or a pastry brush to spread the syrup all over the banana tops.
Sprinkle the bananas with either cocoa powder or cinnamon. Spread the powder all over if you need to. You don't want large clumps or they will smoke in the oven.
Broil in the oven for about 6 minutes, or until they are golden on top.
Enjoy! Top with berries, chocolate chips, chopped nuts, yogurt, ice cream... The possibilities are endless!
