In a heavy bottom stock pot or skillet, whisk together 1/4 cup bacon grease and 1/4 cup all-purpose flour over medium heat. Continue to cook until the mixture browns slightly, about 5 minutes, but be careful not to let it burn.
Add 3 cups whole 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 1 teaspoon kosher salt and 1 teaspoon freshly ground 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!!!
