Chocolate Chip Cookie Brownie Bars are almost too delicious to write about without running to the kitchen to make a batch.

I’m convinced that chocolate chips make the world a nicer place to be. From chocolate chip banana muffins to chocolate peanut butter pie cups to hot chocolate cinnamon rolls, they make good things even better. By all means, make these as soon as you have the chance!

Chocolate Chip Cookie Brownie Bars

Not surprisingly, this recipe calls for a lot of chocolate chips and plenty of sugar. We’re not looking to make healthy chocolate chip cookie bars. We’re looking to bake some rich, sweet, decadent treats that make people beg for just one more.

So, here we have a scrumptious layered dessert bar that features a homemade chocolate chip cookie on the bottom, topped with a brownie layer. Finish off the dessert with a mouth-watering cookie dough frosting on top.

Where did chocolate chips come from?

As I’m writing this, for some reason two questions popped into my mind. I needed to know who invented chocolate chips and whether their halo was made out of chocolate chip cookies?

Her name was Ruth Graves Wakefield of the Toll House Inn in Whitman, Massachusetts. As the story goes, she was known for chopping up Nestle candy bars and putting the bits into a cookie everyone adored.

Toll House Chocolate Chip Cookies were named after her little inn. Due to her cookies’ popularity, Nestle knew Ruth was onto something,

Ultimately, I think Nestle may have given Ruth the shaft.

For this reason, Nestle reached an agreement in 1939 to add her recipe to their candy bar wrapper. In return, she was given a lifetime supply of chocolate. Look, I love chocolate a lot. If it were possible to snarf it up it without any sugar-related health, dental or weight problems, I’d eat it every day, all day. Bring on the chocolate chips!

If I invent something that will make a company millions upon millions of dollars, I want a lifetime supply of money – not chocolate. Poor Ruth. She had no idea what she’d invented or how it would change the world of home bakers everywhere. Hopefully, she spent her life happily surrounded by cookie lovers and chocolate.

Then again, maybe I will take that lifetime supply of chocolate!
