This recipe for toffee cookie bars come straight from my grandma's recipe box. They are a simple brown sugar cookie bar topped with chocolate and optionally pecans for a easy and tasty dessert.
Right after removing the bars from the oven, sprinkle the chocolate chips over the top. Let sit for 1 minute and then spread until smooth. Sprinkle chopped pecans over the melted chocolate if desired.
Allow to cool completely before cutting into bars and serving.
