4. Flatten each biscuit into a 4-inch circle.

5. Spoon about 2 tablespoons of the beef mixture and 1 tablespoon of shredded cheese into the center of each biscuit.

6. Fold the dough over the filling and pinch the edges to seal tightly, forming a ball.

7. Place seam-side down on the prepared baking sheet.

8. In a small bowl, mix melted butter, Parmesan, and garlic powder.

9. Brush the butter mixture over each biscuit bomb.

10. Bake for 13–15 minutes, or until golden brown and cooked through.

11. Brush with remaining garlic butter and sprinkle with parsley before serving.
