Place the softened cream cheese and blue cheese in a small bowl and beat at medium speed until combined and nicely whipped. Set aside.
Prepare the burgers:
Preheat the grill to medium and oil the grates.
While the grill heats, place the ground beef, garlic, and Worcestershire sauce in a medium bowl. Using your hands, gently work the garlic and Worcestershire into the meat, careful not to overwork it as it will get tough. Divide into 4 patties about 1/4" larger than the buns you're using, and make an indent in the center with your thumb to keep shrinking to a minimum. Sprinkle both sides generously with salt and pepper, then grill for about 3 minutes per side for medium rare. Remove from heat, and cover with loosely with foil.
Turn the heat off of the grill and place the buns face down on the grill until warm and slightly toasty.
Assemble the burgers:
Place lettuce and tomatoes on the bottom bun, then top with a burger. Top the burger with a slice of bacon, and spread the whipped blue cheese on the top bun. Place the top bun over the burger, then serve immediately and enjoy!
Notes
The nutrition information includes all of the whipped blue cheese, though you probably won't need it all.
