Line two baking sheets with foil. One pan will be used to prep the bacon. Place a baking rack into the other pan and spray with cooking spray. Set aside.
Separate bacon strips and line up on the pan without the rack. Drizzle maple syrup over the slices and using a pastry brush, evenly distribute it over the top all of the slices. Flip the slices and repeat.
Sprinkle about 2 Tablespoons of brown sugar evenly onto the tops of the maple coated bacon. Use the pastry brush to distribute it evenly. (The sugar will begin to mix with the syrup already on the bacon.) Flip the bacon over and transfer the slices to the baking pan with the rack. Sprinkle another 2 Tablespoons of brown sugar over the tops of the bacon, using the pastry brush again to distribute.
Place baking sheet into a cold oven on the middle rack. Set oven temperature to 350 degrees F. and allow to come to temperature while the bacon is in the oven. Check at 15 minutes, then every 2-5 minutes until bacon is deeply browned and shiny. Keep an eye on it so that the sugar doesn’t burn. About 25-30 minutes
Remove from oven. Allow to cool for a couple of minutes, then serve. Store covered in refrigerator up to 3 days. You can reheat the bacon in the microwave, loosely covered with waxed paper or plastic wrap, for a few seconds per slice.
