Prepare the Beef Filling : In a skillet over medium heat, cook the ground beef until browned, breaking it into crumbles. Drain excess grease. Add minced garlic and sauté for 1-2 minutes until fragrant. Remove from heat and let the mixture cool slightly.
Assemble the Bombs : Flatten each biscuit dough piece into a 4-inch circle. Place a small spoonful of the beef mixture in the center of each circle. Add one cube of cheddar cheese and a small piece of diced Parmesan to the center. Fold the dough around the filling, pinching edges tightly to seal. Roll gently into a ball.
Bake to Perfection : Preheat the oven to 375°F (190°C). Place the prepared balls seam-side down on a baking sheet lined with parchment paper. Brush each bomb with melted butter and sprinkle with chopped parsley for extra flavor.
Bake and Serve : Bake for 15-18 minutes or until golden brown and puffed. Let cool slightly before serving. Enjoy the cheesy, garlicky goodness with your favorite dipping sauces like marinara, ranch, or BBQ sauce!
