Preheat oven to 450°F. In a large mixing bowl, combine flour, sugar, baking powder, garlic powder, salt and whisk. Add in butter and using a pastry cutter or similar device, cut butter into the flour mixture until only small crumbles of butter remain (no bigger than pea-sized). Stir in cheese. Pour in buttermilk and stir with a large wooden spoon or sturdy spatula until everything is just mixed. Be careful not to overmix.
Line two baking sheets with parchment paper. Scoop batter using a 1/4 cup measuring cup, and place batter on baking sheet, about 2 inches apart. Bake about 11-12 minutes until biscuits turn a golden brown.
In a small bowl, mix melted butter, garlic powder and parsley. Brush onto biscuits while they are still hot. Biscuits are best eaten warm.
