Preheat oven to 350 degrees.
Mix brown sugar, cayenne pepper, and chili powder together in a mixing bowl. Add maple syrup and mix until well blended.
Lay bacon strips out flat on cookie sheets that have been sprayed with non-stick cooking spray. I line mine with foil, then spray with non-stick cooking spray.
Spread 1 T of brown sugar mixture over each strip of bacon (there are usually about 12-15 strips in 1 1/2 pounds of thick cut bacon).
Distribute leftover brown sugar mixture over each piece of bacon then press the brown sugar mixture into the bacon with your hands.
Carefully place cookie sheets with bacon into the preheated oven for 30-40 minutes. I set my timer for 30 minutes and check the bacon. If it's not done, I set the timer for another 5 minutes and repeat until the bacon is done. You'll know it's done when it's nice and brown.
Carefully remove the cookie sheets from the oven and immediately transfer the slices of bacon onto parchment paper and allow to cool.
