2 c. all purpose flour
1 c. firmly packed brown sugar
1/2 c. butter, softened
1 c. pecan halves

2/3 c. butter
1/2 c. firmly packed brown sugar
1 c. semi sweet Nestle's chocolate chips

Heat oven to 350 degrees. In large mixer bowl combine all crust ingredients except pecans. Beat at medium speed, scraping bowl often, until well mixed and particles are fine (2 to 3 minutes). Press on bottom of 13"x9" baking pan. Sprinkle pecans evenly over unbaked crust.

In 1 quart saucepan combine 2/3 cup butter and 1/2 cup brown sugar. Cook over medium heat, stirring constantly 1 minute. Pour evenly over pecans and crust. Bake for 18 to 22 minutes or until entire caramel layer is bubbly. Remove from oven. Immediately sprinkle with chips; allow to melt slightly, 2 to 3 minutes. Swirl chips leaving some whole for a marble effect. Cool completely; cut into bars.

Variation: Substitute milk chocolate chips for a different taste.

Yield: 3 dozen.
