Lay the crackers on a rack set on a rimmed baking sheet. Sprinkle Parmesan cheese on half of the crackers and about a teaspoon of brown sugar on the other half.
Slice the bacon in half. Wrap each cracker with a half piece of bacon, tucking the end of the piece underneath the cracker.
Bake them for about 2 hours. The bacon will cook slowly and start to wrap around the crackers. The bacon grease will drip off. Serve them warm on a platter!
Notes
If desired, you can experiment by adding shakes of Tabasco, cinnamon, pepper or other cheeses.
