Preheat oven to 375°.
Lightly spoon flour into dry measuring cups; level with a knife. Combine flour and next 4 ingredients in a bowl; cut in butter with a pastry blender or 2 knives until mixture resembles coarse meal. Stir in raisins.
Combine 1/2 cup milk and egg; add to flour mixture, stirring just until moist. (Dough will be sticky.)
Turn dough out onto a lightly floured surface; knead lightly 4 or 5 times with floured hands. Pat dough into a 7-inch circle on a baking sheet coated with cooking spray. Cut dough into 10 wedges, cutting to, but not through, bottom of dough. Brush with 1 tablespoon milk; sprinkle with cinnamon sugar.
Bake at 375° for 18 to 20 minutes or until golden. Serve warm.
