1/2 cup butter or margarine
1 cup granulated sugar
1 egg
1 teaspoon vanilla extract
1 1/4 cups unsifted all-purpose flour
1/2 cup Hersheys Cocoa
3/4 teaspoon baking soda
1/4 teaspoon salt

Cream butter or margarine, sugar, egg and vanilla extract until light and fluffy.

Combine flour, cocoa, baking soda and salt; add to creamed mixture. Shape soft dough into two 1 1/2-inch rolls. Wrap in wax paper; chill until firm.

Cut one roll into 1/8-inch slices; arrange, edges touching, on bottom and sides of greased 9-inch pie pan. (Small spaces in crust will not affect pie.) Bake at 375 degrees F for 8 to 10 minutes. Cool.

Freeze leftover dough; use for pie crust or cookies.
