Preheat oven to 450F degrees. Spray an oven-safe glass or ceramic 9×9-inch baking dish with nonstick cooking spray.

In a large skillet over medium-high heat, add breakfast sausage and break it up into crumbles. Cook until there is no pink left, about 8-10 minutes. Drain on a paper towel-lined plate and set aside.

In a medium bowl, mix together all-purpose flour, granulated sugar, and baking powder.

Pour in buttermilk. Stir until a sticky batter forms, adding more buttermilk if necessary.

Gently stir in shredded cheddar cheese and cooked sausage until combined well.

In a microwave-safe bowl, melt salted butter, then pour into the prepared baking dish.

Pour biscuit dough into baking dish on top of the melted butter. Spread evenly in the pan.

Cut the dough into 9 squares to help with cutting later.

Bake for about 25-30 minutes, rotating dish once during baking.

Remove when golden brown on top and springy to the touch. Slice and serve!
