Heat oven to 450 degrees F. Spray a cookie sheet lightly with no-stick cooking spray. Place flour in large bowl. Cut in shortening with pastry blender or fork until mixture resembles coarse crumbs. Add milk; stir with fork until soft dough forms and mixture begins to pull away from sides of bowl.
Knead dough on lightly floured surface just until smooth. Roll out dough to 1/2-inch thickness. Cut with floured 2-inch round cutter. Place biscuits with sides touching on prepared cookie sheet.
Bake 10 to 12 minutes or until golden brown. Serve warm.
