Prepare the Sausage:
Shape sausage into patties, roughly the size of your biscuit cutter.
Cook in a skillet over medium heat until browned and cooked through.
Drain on paper towels to remove excess grease.
Make the Biscuit Dough:
In a mixing bowl, combine flour, baking powder, baking soda, and salt.
Cut in cold butter until mixture resembles coarse crumbs.
Slowly stir in buttermilk until just combined; avoid overmixing.
Shape and Bake:
Turn dough onto a floured surface and gently roll out to ½-inch thickness.
Cut biscuits with a round cutter and place on a baking sheet, close together.
Bake in preheated oven at 425°F (220°C) for 12–15 minutes until golden.
Brush tops with melted butter immediately after baking.
Assemble and Serve:
Split biscuits and add sausage patties.
Optional: add cheese, a drizzle of maple syrup, or a fried egg for a hearty breakfast sandwich.
