Preparation / Directions:
Preheat oven to 350 degrees. With mixer, cream butter well; blend in sugar, egg yolk and vanilla. By hand mix in flour, 2/3 cup Heath bits and nuts. Press into ungreased 15 1/2 x 10 1/2 " jelly roll pan. Bake 18 to 20 minutes, or until lightly browned. Remove from oven and immediately sprinkle remaining Heath Bits over top.

NOTE: These are excellent cookies and the kids loved mushing them by hand in the bowl and then pressing them into the cookie sheet. Hands on cooking!!!
