Cookie Brittle

This wonderful recipe appeared on a chocolate chip cookie package years ago, and I've never seen it since. It's a marvelous twist on the traditional chocolate chip cookie recipe, using tender, melting shortbread as the base.
INGREDIENTS:

* 1 cup butter, softened
* 1-1/2 tsp. vanilla
* 1/4 tsp. salt
* 1 cup sugar
* 2 cups flour
* 2 cups semisweet chocolate chips
* 1 cup chopped pecans, OR more chocolate chips

PREPARATION:
Combine butter, vanilla, salt and sugar and beat together until well blended, using the back of a spoon. Stir in flour until just mixed. Add chocolate chips and nuts. Press cookie dough evenly into a 15x10" jelly roll pan.

Bake at 375 degrees for 15-25 minutes, until light golden brown. Check at the 15 minute bake time, then watch cookies carefully; they go from light brown to burnt around the edges very quicky. Let cool in pan. When cool, break into irregular pieces. Store in airtight container. 16 servings
