Bananas Foster over Puff Pastry

Ingredients:
1 puff pastry sheet, thawed
6 medium bananas, sliced
1/2 c. brown sugar
2 T. butter
1 T. lemon juice
1/2 t. cinnamon

Directions:
1. Preheat oven to 425 F.
2. Cut puff pastry into a 9" circle (I don't think this is neccesary, you could just have a square instead). Bake for 10 minutes until golden brown. Let it cool completely on a wire rack.
3. Cook the sugar, butter, lemon juice & cinnamon in a sauce pan for 5 minutes over medium heat until slightly thickened. Toss in the bananas to coat.
4. Spoon the bananas onto the pastry. Serve with whipped cream.
