Colossal Cookie

Beat sugar, brown sugar and margarine until creamed well. Beat in egg and vanilla.

Mix dry ingredients; blend into mixture. Stir in 1 cup chocolate chips.

Place dough in refrigerator for 1 1/2 hours or for 45 minutes in freezer until well chilled, but not hard (chilling makes dough less sticky and helps prevent excessive spreading).

Grease a 12-inch round foil or pizza baking pan. Press evenly to within 1 1/2 inches of edge of pan.

May sprinkle additional 1/4 cup chocolate chips on top, pressing into dough slightly for easy handling.

Set pan on cookie sheet.

Bake in center of 325° oven for 15 to 20 minutes, or until edges are firm and center has no indentation when lightly touched.

Place on wire rack; cool completely.

When cool, remove from pan and wrap.
