Cut four 14"x12" pieces of waxed paper or plastic wrap; set aside. In a bowl,
cream butter or margarine, sugar, eggs, and vanilla until light and fluffy. In
a bowl, combine flour, baking soda and cocoa powder. Stir flour mixture into
sugar mixture until evenly distributed.
Divide dough into 4 pieces. Shape each piece into and 8 to 10 inch roll. Wrap
each roll in waxed paper or plastic wrap. Place in freezer container with a
tight-fitting lid, or wrap airtight in a piece of foil. Label and date. Store
in freezer. Use within 6 months.
To make cookies:
Slightly thaw a roll of dough. Preheat oven to 350F. Lightly grease baking
sheets. Slice dough into slices or chunks. Arrange slices on prepared baking
sheets about 1/2 inch apart. Bake 8 to 10 minutes until cookies are set on
edges and slightly firm on top. Remove cookies and cool on wire racks.
