In a large mixing bowl, combine the ground beef with ketchup, mustard, garlic powder, salt, and pepper. Mix until incorporated.

Divide the beef mixture into 8 equal portions and flatten each into a small patty. Place cheese, onions, and pickles in the center, then mold the beef around the filling.

Wrap each beef ball in a slice of bacon, covering fully and securing with toothpicks if needed.

Preheat the oven to 400°F (200°C). Lightly spray a baking sheet with olive oil and arrange the wrapped bombs on it. Bake for 25 to 30 minutes.

Let the bombs rest for about 5 minutes before serving warm with dipping sauces like ketchup, ranch, or aioli.
