1/2 c. butter
1/4 c. + 2 tbsp. granulated sugar
1/4 c. + 2 tbsp. brown sugar
1/2 tsp. vanilla
1 egg
1 c. flour
1/2 tsp. baking soda
1/2 tsp. salt
1/2 c. coarsely chopped walnuts
1 (6 oz.) pkg. chocolate chips

Heat oven to 375 degrees. Grease oblong pan. Mix butter, sugars and vanilla thoroughly. Beat in egg. Blend in flour, soda and salt. Mix in walnuts. Spread in prepared pan. (Mixture will be like wallpaper paste; don't worry.) Sprinkle chocolate chips over top of dough. Place in oven one minute. Remove from oven and run knife through dough to marbelize. Return to oven for 12 to 14 minutes. Cool. Makes about 2 dozen.

(I usually make a double recipe in a pan approximately 10"x14", so the baking time is about 20 minutes.)
