Preheat oven to 400° F.
Cut each biscuit into quarters and set aside.
Spray cooking spray into a 9 x 13 pan.
Layer half of the quarters in prepared pan.
Bake for 10 minutes.
While biscuits are cooking, brown the sausage over a medium/high heat until cook through.
Reduce heat to medium.
In a small bowl, mix together flour, salt, pepper and garlic powder.
Sprinkle the cooked sausage with flour mixture and stir mixture until completely absorbed.
Next, add in milk and stir to combine.
Stir frequently until mixture comes to a simmer.
Reduce heat to low and continue to simmer and stir until gravy has started to thicken, (about 5 mins).
Pour gravy over your bottom layer of cooked biscuits.
Layer the remaining uncooked, biscuit pieces over the gravy.
Bake for 15-20 minutes or until biscuits are golden brown.
If you would like, brush 1-2 Tablespoons of melted butter over the tops of the biscuits to give them an inviting shine.
Let cool for a few minutes.
Enjoy!
