4 1/2 cups flour
4 teaspoons baking powder
1 teaspoon salt
1/2 pound (2 sticks) unsalted butter -- softened
2 cups sugar
1/2 cup milk
1/2 teaspoon vanilla extract
Preheat the oven to 375 degrees. Butter baking sheet or line with parchment paper. Sift together the dry ingredients.
Cream the butter and sugar until fluffy. Add the eggs and beat well. Add the dry ingredients, 1 cup at a time, alternating with the milk and vanilla, beating well after each addition. Wrap and chill dough for at least an hour.
Divide the dough into 4 pieces. Roll 1 piece at a time on a floured board and cut with large cookie cutters. Bake for 8-10 minutes. Cool on racks.
