Bake: Transfer the tray to the oven and bake for 20-25 minutes, or until the bacon is crisp and the sugar is melted and bubbly.
Cool and serve: Let cool for a few minutes before serving. The sugar will harden slightly as it cools.
Notes
Use regular-cut bacon for the best crispness in the same time the crackers are done.
A wire rack helps air circulate so the bottoms stay crisp.
If making ahead, store in an airtight container and reheat at 300°F for 5 minutes.
