Notes
Don't Over-Bake - be sure not to go over the recommended baking time. These are meany to be chewy!
Storage - store these bars covered or in an airtight container, either at room temperature or in the refrigerator.
No-Sticking - I find that just greasing my baking dish with cooking spray works to make sure these bars don't stick but if you want, you can add some parchment paper to the bottom too.
