Step 1: Preheat your oven to 375°F (190°C). Lightly grease a baking sheet or line it with parchment paper for easy cleanup.
Step 2: Separate the refrigerated biscuit dough into individual biscuits. On a lightly floured surface or a piece of parchment paper, gently flatten each biscuit until it's about 3-4 inches in diameter.
Step 3: Place one half of a mozzarella string cheese stick (or 1-2 small mozzarella cubes) in the center of each flattened biscuit.
Step 4: Carefully gather the edges of the biscuit dough around the cheese, bringing them together at the top. Pinch the seams tightly to completely seal the cheese inside.
Step 5: Place the sealed biscuit bombs seam-side down on your prepared baking sheet, leaving a little space between each one. In a small bowl, melt the unsalted butter and stir in the garlic powder, Italian seasoning, and grated Parmesan cheese.
Step 6: Brush the melted butter mixture generously over the tops and sides of each biscuit bomb. Bake for 12-15 minutes, or until the biscuits are golden brown and puffed up, and the cheese inside is molten and gooey.
Step 7: Remove from the oven and let cool for a minute or two before serving. These are best enjoyed warm with your favorite dipping sauce.
