Preheat oven to 450°.
Lightly spoon flour into a dry measuring cup; level with a knife.
Combine flour and next 3 ingredients in a bowl; cut in butter with a pastry blender or 2 knives until mixture resembles coarse meal. Add buttermilk; stir just until moist.
Turn dough out onto a lightly floured surface; knead 4 or 5 times. Roll dough to 1/2- inch thickness; cut with a 2 1/2-inch biscuit cutter. Place on a baking sheet coated with cooking spray. Bake at 450° for 10 minutes or until golden. Serve warm with butter and honey, if desired.
