Preheat the oven to 375°F (190°C) and grease a baking sheet.

In a small bowl, combine the melted butter, garlic, and grated Parmesan. Set aside.

Cook the ground beef in a skillet over medium heat until browned and cooked through. Drain excess fat and season with salt and pepper.

Cut the mozzarella cheese into small cubes or use pre-shredded cheese.

Open the biscuit dough and separate the biscuits. Flatten each biscuit slightly with your hands.

Place a spoonful of cooked ground beef in the center of each biscuit, followed by a piece of mozzarella cheese.

Fold the edges of the biscuit dough over the filling, pinching the edges to seal it inside.

Place the sealed dough balls onto the prepared baking sheet.

Brush the top of each dough ball with the garlic Parmesan butter mixture.

Bake in the preheated oven for 12-15 minutes, or until the dough is golden brown and cooked through.

Serve hot and enjoy!
