1 c. all-purpose flour
1/2 c. brown sugar (firmly packed)
3 tbs butter or margarine (room temperature)
1/2 c. brown sugar (firmly packed)
1/2 c. butter or margarine
1 c. pecans (chopped)
1 tsp. vanilla flavoring

Preheat oven to 350 degrees. Mix flour, 1/2 c. brown sugar and 3 tbs butter on low speed until blended. Increase speed to medium and mix for two minutes or until mixture is crumbly. Press onto bottom of ungreased 9 x 9 x 2 or 8 x 8 x 2 square pan. Cook 1/2 c. brown sugar and 1/2 c. butter over medium heat stirring consistently, until ingredients begin to boil. Continue to boil and stir for 1 minute. Stir in pecans and vanilla flavoring. Pour over layer. Bake for 18 – 20 minutes or until topping is bubbling. Sprinkle with chocolate chips. Bake for 2 additional minutes to soften chocolate (do not spread mixture). Cool for 10 minutes; with knife, loosen edges and cut into 6 by 6 rows. May be covered and stored in refrigerator.
