bubble down over the crackers.
Place the baking sheet on the middle rack of the preheated oven. Bake for 40–60 minutes, or until the bacon is cooked through, the brown sugar is melted and bubbling, and the crackers are a deep golden color.
The exact time will depend on your oven and the thickness of your bacon; start checking around 40 minutes and continue baking until the bacon looks crisp and the sugar looks syrupy and glossy.
