Gingerbread for houses and cookies

Here is my favorite gingerbread recipe. I like it because it calls for margarine, which is significantly less expensive than butter, and when you are making a lot of dough for a large gingerbread house it's nice not to use the expensive ingredients. Try it out!

Ingredients

1/2 cup margarine or shortening
1/2 cup sugar
1/2 cup molasses
1 egg yolk
2 cups sifted all-purpose flour
1/2 teaspoon salt
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon ground cinnamon
1 teaspoon ground cloves
1/2 teaspoon ginger
1/2 teaspoon ground nutmeg

Directions

In a large bowl, cream together the margarine and sugar until smooth. Stir in molasses and egg yolk. Combine the flour, salt, baking powder, baking soda, cinnamon, cloves, ginger, and nutmeg; blend into the molasses mixture until smooth. Cover, and chill for at least one hour.
Preheat the oven to 350 degrees F (175 degrees C). On a lightly floured surface, roll the dough out to 1/4 inch thickness. Cut into desired shapes with cookie cutters. Place cookies 2 inches apart on ungreased cookie sheets.
Bake for 8 to 10 minutes in the preheated oven, until firm. Remove from cookie sheets to cool on wire racks. Frost or decorate when cool.
