3/4 cup shortening
1 (3 ounce) package yellow cake mix
1 3/4 cups white sugar
1 teaspoon vanilla extract
1 cup crunchy non-instant chocolate chip cookies
Grease a 10x15 inch baking dish.
In a medium saucepan or over a double boiler, heat the shortening and brown sugar until the mixture thickens. Do not simmer, just stir and cook until the mixture is smooth.
In a small bowl, stir together the cake mix and 3/4 cup of sugar. Spread this mixture evenly over layer of cookies. Let cookies stand overnight, then dust with some of the melted chocolate chips.
