Prepare the Filling : In a large skillet, cook the turkey bacon over medium heat until crispy. Remove and set aside. Using the same skillet, cook the ground beef and onions until the beef is browned and fully cooked. Drain excess grease. Add the cream cheese, ketchup, barbecue sauce, mustard, and Worcestershire sauce. Stir until well combined. Remove from heat and mix in the cooked turkey bacon. Set aside to cool slightly.

Assemble the Cheeseburger Bombs : Preheat your oven to 375°F (190°C). Flatten each Pillsbury biscuit into a 4-inch circle. Place a small scoop of the beef mixture in the center of each biscuit. Top with a cheddar cheese square. Fold the edges of the biscuit dough around the filling, pinching it tightly to seal. Roll gently into a ball.

Add Garlic Parmesan Topping : Arrange the sealed bombs seam-side down on a baking sheet lined with parchment paper. Brush each bomb with the beaten egg white. Sprinkle sesame seeds, garlic powder, and Parmesan cheese on top for extra flavor.

Bake to Perfection : Bake in the preheated oven for 12-15 minutes, or until the biscuits are golden brown and puffed. Remove from the oven and let cool for 5 minutes before serving.

Serve and Enjoy : Serve warm, paired with your favorite dipping sauces like ranch, barbecue, or ketchup.
