In a large bowl, combine shredded pulled pork, barbecue sauce, and ¾ cup of the cheese. Mix until well combined.
Butter or spray with nonstick spray a 12-cup muffin pan. Split 6 of the biscuits horizontally by gently peeling them apart at the middle layer. Using a tamper tool, press one of the biscuit halves in each of the muffin tins so that it covers the bottom at up the sides. Alternatively, flatten the biscuit halves with your fingers on a flat surface so that they become 4 inches in diameter, and then press into the muffin tins.
Fill each muffin tin with 3-4 tablespoons of the prepared cheesy barbecue pork filling.
Evenly sprinkle the remaining cheese on the tops of each filling.
Bake for 14-16 minutes, or until the cheese is melted and edges of biscuits are golden brown.
Gently run a knife around the edge of each biscuit to loosen, then transfer to a serving tray. Optional, serve with toppings.
