This is one of my favorite recipe. I'm thinking of making one this weekend!
1 cup butter
3/4 cup brown sugar
1 1/2 cup chocolate chips or wafers
2 cups flour
1 cup brown sugar
1/2 cup softened butter
1 1/2 pecan halves
Mix first three ingredients. Press firmly into 9x13 inch pan. Place pecans evenly over crust. Heat remaining brown sugar and butter, stirring constantly, up to boiling. Boil for 1 minute. Pour evenly over pecan crust. Bake at 350 'F for 20 minutes. Remove from oven and sprinkle evenly with chocolate. Cool and cut into squares.
