Preheat oven to 375°F (190°C).

In a bowl, combine flour, sugar, baking powder, ground cinnamon, and salt.

Cut in chilled butter using a pastry blender or knives until the mixture resembles coarse meal.

Stir in raisins.

In a separate bowl, combine 1/2 cup milk and egg.

Add the milk and egg mixture to the flour mixture, stirring until just moist.

Turn dough out onto a lightly floured surface.

Knead lightly 4-5 times.

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, the bottom.

Brush with 1 tablespoon milk.

Sprinkle with cinnamon sugar.

Bake for 18-20 minutes, or until golden brown.

Serve warm.
