Sugar Snaps

½ cup butter

½ cup shortening

2 cups white sugar

4 egg yolks

1 teaspoon vanilla extract

2 cups all-purpose flour

1 teaspoon baking soda

¼ teaspoon salt

Preheat oven to 300 degrees F (150 degrees C).

In a medium bowl, cream together the butter, shortening, and sugar. Beat in the egg yolks one at a time, then stir in the vanilla. Combine the flour, baking soda, and salt; stir into the creamed mixture. Roll dough into walnut size-balls and place 2 inches apart onto an unprepared cookie sheet.

Bake for 20 minutes in the preheated oven. Cool on wire racks.
