Bake the biscuits according to the package directions. Set aside and keep warm.
In a large skillet over medium-high heat, cook the sausage until fully browned. Do not drain the grease.
Add butter to the skillet and stir until melted.
Sprinkle in the flour and cook for about 1 minute, stirring constantly to form a roux.
Gradually whisk in the milk, stirring continuously to prevent lumps.
Add garlic powder, salt, and black pepper. Simmer over medium heat, stirring often, until the gravy thickens.
Split the warm biscuits in half and spoon the sausage gravy generously over the top.
Enjoy!
