Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
In a medium bowl, combine the ground beef, kosher salt, and black pepper, then form into 8 equal-sized meatballs, each about 1.5 inches in diameter.
Flatten each biscuit dough round into a 4-inch circle, place one meatball in the center, and wrap the dough around it, pinching the seams to seal completely into a smooth ball.
Arrange the sealed bombs seam-side down on the prepared baking sheet, spacing them 2 inches apart, and bake for 18-20 minutes until the biscuits are golden brown and the meat is cooked through.
While the bombs bake, mix the softened cream cheese, mayonnaise, grated Parmesan, and minced garlic in a small bowl until smooth and fully combined.
Brush the hot baked bombs with melted butter immediately after removing them from the oven, then dollop each with a tablespoon of the garlic Parmesan sauce and sprinkle with chopped parsley before serving.
