Preheat to oven broiler to high heat and lightly spray a baking sheet with non-stick spray. Do not use parchment paper.
In a mixing bowl, combine peanut butter and cream cheese. Mix until well combined and smooth. Spread onto the sliced side of each bagel half and place onto the baking sheet - peanut butter side facing up.
Slice the banana into 1/4 inch circles and place on top of the peanut butter mixture. Lightly sprinkle the coconut sugar on the top of each banana.
Place in oven and broil until the sugar on top of the bananas is browned and caramelized, about 3 to 5 minutes. Allow to cool slightly before serving.
