Lightly spoon flour into dry measuring cups; level with a knife. Combine flour, baking powder, salt, and pepper in a medium bowl; stir well with a whisk.
Cut in butter with a pastry blender or 2 knives until mixture resembles coarse meal. Add cheese; toss well to combine. Add buttermilk; stir just until moist. (If too dry add another tablespoon buttermilk.) Drop dough into 8 equal mounds on a baking sheet coated with cooking spray.
Bake at 450° for 13 minutes or until edges are lightly browned.
