Step 1: Preheat Oven
Preheat your oven to 375°F (190°C). Grease a muffin tin or line with paper liners.

Step 2: Hydrate the Stuffing Mix
In a bowl, combine stuffing mix and broth. Let sit for 5–10 minutes so the stuffing absorbs the liquid and softens.

Step 3: Prepare the Dough
In a separate bowl, whisk together flour, baking powder, baking soda, salt, and garlic powder. In another bowl, whisk the egg, sour cream, and melted butter.

Step 4: Combine Everything
Add the wet ingredients to the dry, then fold in the soaked stuffing. Stir gently until fully combined. Add any optional ingredients now (e.g., turkey or sausage).

Step 5: Scoop and Bake
Spoon the dough into muffin cups or onto a baking sheet in rounded mounds. Bake for 18–22 minutes or until the tops are golden and a toothpick comes out clean.

Step 6: Cool and Serve
Let the biscuits rest for 5 minutes in the pan, then transfer to a wire rack. Serve warm with butter, gravy, or alongside apple-stuffed turkey.
