Preheat oven to 375°F. Line a sheet pan with parchment and set aside.
Cook bacon in a large skillet over medium heat until crisp. Transfer to a plate; drain most of the fat.
Sauté onion in 1 tsp bacon drippings or olive oil until soft, about 3 minutes.
Brown the ground beef with the onions, breaking it up finely. Drain excess grease.
Stir in ketchup, mustard, Worcestershire, garlic powder, salt, and pepper. Fold in bacon and pickles. Cool 5 minutes.
Divide dough into 12 pieces. Flatten each into a 3-inch round.
Spoon some beef mixture into the center and add a cheese cube. Wrap dough around and pinch to seal.
Arrange seam-side down on the pan. Brush with melted butter mixed with milk; sprinkle sesame seeds if using.
Bake 14–18 minutes until deeply golden. Rest 5 minutes before serving.
