Preheat the oven to 425 degrees F.On a lightly floured surface, roll the puff pastry out into a rectangle about 1/4 inch thick. Place the pastry on a parchment lined baking sheet. Using a sharp knife, score a 1 inch border around the edge. Brush the pastry all over with melted butter, sprinkle the cinnamon around the edges. Arrange the chocolate in an even layer over the pastry, leaving a 1-inch border around the edge of the pastry. Lay the bananas, cut side up in an even layer over the chocolate. Drizzle the bananas with honey. Transfer to the oven and bake for 20-25 minutes or until the edges are dark golden brown and the bananas are beginning to caramelize. It's OK if the edges get dark. Let cool slightly and serve warm with honey and ice cream, if desired. Enjoy!
