Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.

In a large mixing bowl, whisk together flour, baking powder, salt, garlic powder, onion powder, sage, thyme, and black pepper.

Cut in the cold butter until the mixture resembles coarse crumbs with some pea-sized pieces.

Stir in the crumbled stuffing mix and chopped parsley until just combined.

Gradually pour in the buttermilk and mix gently until the dough comes together.

Turn the dough onto a floured surface and shape it into a 1-inch thick rectangle. Cut out biscuits using a round cutter.

Place biscuits on the baking sheet, brush with melted butter, and sprinkle with cheddar cheese if desired.

Bake for 12-15 minutes or until golden brown. Optionally brush with more melted butter after baking.
