OH MY STARS! I am so, so, so very happy that I stumbled onto this recipe. Listen to me talking like it’s a new recipe that I just found.
It isn’t. I’ve had it all along!

See, I like chocolate desserts. Well, my husband REALLY likes chocolate desserts. And I bake for a decent sized group of people often – mostly mine or my husband’s co-workers. Occasionally for my MOPS group.

When I cook for a fairly large group, I love using my half-sheet pans. They just produce a lot of desserts with pretty minimal effort. What’s not to love?

I had a Monster Cookie Bar recipe. I had a Salted Nut Roll recipe. A Pumpkin Bar recipe. A Mississippi Mud Brownie recipe. A Sugar Cookie Bar recipe. A Banana Bar recipe.  Oh yes, I had all kinds of options.

But I really wanted a chocolate chip cookie bar recipe. Kind of like a Monster Cookie Bar without all the stuff that made it Monster (the peanut butter, the oatmeal, the M&Ms).  I had one in a 9×13 size, but that didn’t quite make as many bars as I wanted to. So, one day, I just said “Forget it! I’m going to experiment.”

So I did. I just took my normal made-for-a-9x-13-pan-chocolate-chip-cookie-bar recipe and made 50% more. IT WAS PERFECT!!! I even like it better this way – the bars are thinner, making them easier to hold and easier to eat. They’re just everything that I wanted them to be!

Since then, I’ve made them several times. They’re honestly my new Go To recipe because they’re just so stinking easy and so wonderfully tasting! In fact, I made a batch for the teachers at my son’s school and he came home with an A that day – it wasn’t even report card time! (Kidding, but they did love them!)
