Line 2 baking sheets with tin foil and then put a wire rack on top of each baking sheet. If you don't have 2, you can cook the bacon in 2 separate batches.
In a small bowl, whisk together the grewed coffee and brown sugar until full combined. Set aside.
Evenly spread out the bacon on the wire rack(s). It's okay to overlap it a little but not too much.
Sprinkle half of the ground coffee (only a 1/4 of it if you're baking in batches) on top of the bacon.
Using a cooking brush, brush the tops of the bacon with the brown sugar glaze.
Turn the bacon over and repeat the steps of sprinkling it with sugar and then brushing it with the glaze.
Bake for 15 minutes, flip the bacon, and then bake for an additional 10-15 minutes or until bacon is at your desired crispiness.
Let bacon cool on paper towels to soak up the excess grease, serve, and ENJOY!!
