Adjust oven rack to center position and preheat oven to 350°F. Generously grease a full-sized bundt pan with butter and set aside.
Use sharp kitchen shears to carefully snip the bacon into pieces into a large pot set over medium high heat. Cook, stirring frequently, until crispy. Drain bacon on a paper towel-lined plate and set aside; pour the grease from the pot. In the same pot, cook the ground beef until browned; stir in the minced garlic and cook for a minute more. Generously season with salt and pepper, to taste; set aside.
Quarter the biscuits and place in a large bowl. Pour the melted butter, cooked beef, cooked bacon, and half of the cheese over the top and immediately toss/stir to combine. Transfer the biscuit mixture into the prepared bundt pan, sprinkling more cheese between the layers until all of the cheese has been used up. Make sure the top of the biscuit mixture is fairly level once the pan is full.
Bake for 30 to 45 minutes, until the biscuits are cooked through and golden on top. Check frequently and cover with a sheet of foil if the tops start to get too dark. Allow the pan to rest on a cooling rack for 5 minutes before loosening the edges of the monkey bread with a plastic knife, placing a large plate or platter over the top, and overturning. Serve immediately, pulling apart and topping with optional garnishes.
