6 oz (12 Tablespoons butter), melted, browned and slightly cooled
3/4 – 1 cup brown sugar

If you’re not serving the cookie bars right away, store them in the baking pan until you are ready to cut and serve them so they stay fresh longer.
They are best eaten the same day, but you can store leftovers in the same baking dish, covered or in an airtight container, or a large ziplock bag.
You can also freeze the chocolate chip cookie bars for up to 3 months.
