In a mixing bowl, combine ground beef, salt, black pepper, garlic powder, and onion powder. Mix gently and form into 12 small patties.
Cook the bacon in a skillet over medium heat until crispy. Remove and drain on paper towels.
In the same skillet, cook the patties for 2-3 minutes per side, pressing slightly for a golden crust.
Brush BBQ sauce over each patty while still in the pan, allowing it to caramelize slightly.
Place a slice of cheddar cheese over each patty, cover, and let melt for 1 minute.
Toast the slider buns with butter in a pan until golden brown.
Assemble sliders by placing each patty on a bun, adding a piece of bacon, and topping with extra BBQ sauce if desired.
