Preheat oven to 325°F. Line a 9×12 inch baking sheet with parchment paper and spray with cooking spray. In a medium skillet, cook the bacon until almost done (about 5 minutes). Transfer to a plate with paper towels, to drain. Roll out crescent rolls or puff pastry onto parchment. Pinch seams to make one single sheet. Prick all over with a fork. Drizzle with half of the maple syrup. Sprinkle a half cup of brown sugar over the dough. Top with the cooked bacon, distributing evenly. Sprinkle the remainder of the brown sugar and drizzle with the remaining maple syrup. Bake for about an hour, or until golden-brown (note: it could take less than an hour, depending on your oven). Let cool and harden completely before slicing into pieces.
