Christmas Cranberry Cookies

Preparation

1. In a bowl, cream the butter, sugar and vanilla with an electric mixer until light and fluffy, about 5 minutes. Add the egg and stir to combine. Add the cranberries.
2. In another bowl, combine the flour and baking powder. Stir in the previous mixture with a wooden spoon.
3. On a work surface, roll the dough into two logs, 1 1/2 inches (4 cm) in diameter. Wrap in aluminum foil and refrigerate for at least 2 hours.
4. With the rack in the middle position, preheat the oven to 350 °F (180 °C).
5. Remove the dough from the refrigerator. Unwrap and place the logs on a work surface. Cut into ¾-cm (1/3-inch) thick slices and place the slices on a baking sheet lined with parchment paper. Brush the cookies with a little milk and sprinkle with the vanilla sugar.
6. Bake for about 12 to 14 minutes or until the cookies begin to brown.
