Softening Brown Sugar + An Easy Dessert Recipe

I have a large bag of brown sugar, that went really hard.
It became hard as a rock -
too hard to put in measuring cups, and bake with.
But, I hated to throw it out.
I googled how to soften brown sugar, and saw this tip:

Put your hard sugar in an air tight container with a piece of bread.
(I also put in a couple drops of water, too).
Then cover it with a lid.

I wasn't sure if it would work. I was a little skeptical.

WaaLah! It did work, I had super, soft brown sugar after a couple of days.
I love how this tip gives us a good reason to use the heels of our bread, too!

My soft, brown sugar was perfect for making this EASY, yummy dessert.

Recipe tips after making it a few times:
We like using less chocolate chips, and more caramel.
Give the bars enough time to cool (1 hour +), to cut and serve.
