1. **Preheat:** Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.

2. **Cook Beef:** In a large skillet over medium-high heat, cook the ground beef and onion until the beef is browned and the onion is soft. Drain any excess grease.

3. **Season:** Stir in the Worcestershire sauce, ketchup, garlic powder, salt, and pepper. Cook for 1 minute longer to combine flavors. Remove from heat and **let cool completely** (hot meat will melt the dough).

4. **Prep Dough:** Separate the biscuits. Flatten each biscuit with your hand or a rolling pin into a larger circle (about 4-5 inches wide).

5. **Assemble:** Place a spoonful of the cooled beef mixture into the center of each biscuit circle. Press a cube of cheddar cheese into the middle of the beef.

6. **Seal:** Gather the edges of the dough up around the filling and pinch them tightly together to seal into a ball. Make sure there are no gaps.

7. **Bake:** Place the bombs seam-side down on the prepared baking sheet. Bake for 15–18 minutes, or until the biscuits are golden brown.

8. **Top:** While they bake, mix the melted butter, minced garlic, parsley, and parmesan cheese in a small bowl. Brush this mixture generously over the hot bombs as soon as they come out of the oven.

9. **Serve:** Serve warm, optionally with burger sauce or ketchup for dipping.
