I love the Nature Valley Granola Thins, one side is coated in chocolate or peanut butter, although these aren't coated they're a cheap alternative!
1 cup brown sugar
1 stick butter
1/2 tsp baking soda
1 tsp vanilla
Mix all of the ingredients, pat firmly into a 9x13 pan. Bake at 325* for 18 minutes. Cut upon removing from the oven then allow them to cool.
