1 1/4 c. butter, softened
2 c. sugar
2 eggs
2 tsp. vanilla
2 c. flour
3/4 c. Hershey's cocoa
1 tsp. baking soda
1/2 tsp. salt
1 c. finely chopped nuts (optional)

Cream butter and sugar in large bowl. Add eggs and vanilla; blend well. Combine flour, cocoa, baking soda and salt; blend into creamed mixture. Stir in nuts. Drop by teaspoonfuls onto ungreased cookie sheet. Bake at 350 degrees for 8 to 9 minutes. (Do not overbake. Cookies will be soft. They will puff during baking, flatten upon cooling.)
