Christmas Sugar Cookies

2 sticks (1 cup) butter, softened
1 cup white sugar
2 eggs
1 tsp vanilla extract
33⁄4 cups all-purpose flour
2 tsp baking powder
1⁄4 cup heavy cream
1⁄2 cup colored sugar, for decoration

In a medium bowl, cream together the butter and sugar. Stir in the eggs and vanilla. Sift together the flour and baking powder, stir into the creamed mixture alternately with the heavy cream. Cover dough, and chill for 2 to 3 hours, until firm. Heat the oven to 350°F. Grease cookie sheets. On a lightly floured surface, roll out the dough to 1⁄4-in. thickness. Cut into desired shapes with cookie cutters. Place cookies 1 in. apart on the prepared cookie sheets. Sprinkle with colored sugar if desired. Bake for 12 to 14 minutes, until bottoms and edges of cookies are light brown. Remove from baking sheet and cool on wire racks.
