Preheat oven to 400°F and grease a baking dish. (About 8x10-inches works well.)
Open can of biscuits and cut each biscuit into quarters. Layer half of those quarters in the bottom of the prepared pan. Bake for 10 minutes, then set aside.
Meanwhile, in a large skillet, brown the ground sausage until cooked through.
Sprinkle sausage with flour, and cook 1-2 minutes, stirring with a wooden spoon.
On medium heat, slowly stir in milk. Cook until gravy comes to a low boil and starts to thicken, stirring frequently. Season with salt and black pepper.
Pour gravy over cooked biscuits. Layer remaining biscuit quarters over the gravy and bake until golden brown, 14-18 minutes.
Serve and enjoy!
