In a heavy bottom stock pot or skillet, whisk together bacon drippings and flour over medium heat. Continue to cook until the mixture browns slightly, about 5 minutes, but be careful not to let it burn.
Add milk, 1 cup at a time, whisking thoroughly with each addition. Continue to whisk over medium heat until gravy is smooth and begins to thicken. Add salt and pepper.
Serve over warm biscuits and top with chopped bacon pieces.

Notes
1. In order for me to get 1/4 cup of bacon drippings, I had to cook an 18-ounce package. Since some people already have bacon drippings on hand, I didn't say that an 18-ounce package of bacon was necessary. Plus, depending on your bacon, you might need less to get that 1/4 cup of drippings (my bacon was pretty lean). I do, however, recommend reserving 4 pieces of cooked bacon to chop and add to the top of the bacon gravy. 2. Love my recipe for Flaky Buttermilk Biscuits! Homemade is always best!!!
