This recipe is from a 1993 Tupperware Cookbook. It makes about 6 dozen cookies.
1/2 cup butter or margarine, softened
1 cup packed light brown sugar
1 tsp vanilla
1 1/2 cups all-purpose flour
1/3 cup unsweetened cocoa
1/2 tsp baking soda
1 cup chopped pecans
1 cup flaked coconut
Cream butter and sugar in a large bowl until blended. Beat in the egg and vanilla.
Combine flour, cocoa, baking soda and pecans in small bowl until well blended. Add to the creamed mixture, blending until stiff dough is formed.
Sprinkle the coconut on a work surface. Divide dough into 4 parts. Shape each part into a roll, about 1 1/2-inches in diameter; roll in coconut until thickly coated. Wrap tightly; refrigerate until firm, at least 1 hour or up to 2 weeks. (For longer storage, freeze up to 6 weeks.)
Preheat oven to 350 degrees.
Line cookie sheets with parchment paper or leave ungreased.
Cut rolls into 1/8-inch thick slices and place 2-inches apart on the cookie sheets. Bake at 350 degrees for 10 to 13 minutes or unti firm but not overly browned.
Remove cookies from cookie sheets and cool completely on wire racks.
