1 stick butter, softened
1/3 c. brown sugar
1/4 c. sugar
1 egg
1 tsp. vanilla
1/4 tsp. baking soda
1/4 tsp. salt
1 1/3 c. flour
1 (6 oz.) pkg. chocolate chips

Cream butter and sugars until smooth. Add egg and vanilla and mix well. Add dry ingredients and mix. Stir in chocolate chips. Spread on greased 14 to 15 inch pizza pan (leave about 1/2 inch space next to edge, as cookie will spreadout). Bake at 350 degrees for 15 to 20 minutes, or until golden brown. Decorate when cool. Enjoy!
