When you love S’mores Cookie Bars but are craving a massive amount of chocolate, you make S’mores Double Chocolate Chip Cookie Bars!

These S’mores Bars are bursting with chocolate flavor and gooey marshmallow filling. Basically, they’re perfect.

I’ve probably mentioned this before, but I have unbelievably poor peripheral vision.

Or perhaps it’s not the periphs, but rather my inability to judge the proper distance between my body and an object.

Luckily this is not a problem with anything else, such as my ability to drive (don’t worry, guys, I’m a fabulous driver and can parallel park like a champ), and is only an issue with me sideswiping doorways and misjudging corners.

It’s not a significant problem, but it is rather embarrassing when it happens in public.

Like the time in college where I unintentionally rammed my shoulder into the doorway of a classroom (in front of a cute boy, of course).

(I’d like to say this was an isolated incident, but my shoulder and a doorway have met more times than a doctor and a hypochondriac.)

Or the time I bumped into a clothing rack display and knocked half of the contents onto the store floor.

You’d think, given the amount of times this has happened, I’d be more adept at navigating myself around things, but… apparently not.

All right…on to your regularly scheduled programming: S’mores Double Chocolate Chip Cookie Bars.

All right, so apparently it’s the year of the cookie bar.

I’ve managed to make and share three cookie bar recipes with you already and here I am sharing a fourth.

Let’s review. I’ve shared these easy cookie bar recipes:

Every single one of those recipes were near perfection (I know, I sound like I’m bragging, but, guys, YOU HAVE TO TRY THEM ALL…but really, bake them, try them, love them).

My favorite part of this S’mores Double Chocolate Chip Cookie Bars is the use of chocolate graham crackers. I haven’t had chocolate graham crackers in years, and I’ve forgotten just how good they are. They taste like rich chocolate and childhood afternoons.

The chocolate graham crackers replace some of the flour in the recipe, making the s’mores cookie bars extra rich and indulgent.

The rest of the chocolate flavor comes from cocoa powder and chocolate chips. These bad boys are the Richie Rich of cookie bars.

S’mores Double Chocolate Chip Cookie Bars Tips & Tricks:

I used a whole jar (8 oz) of marshmallow fluff (aka marshmallow creme), but you can use less if you prefer them to be less gooey (i.e., marshmallow fluff oozing out of each bar 🤣).
Be careful not to over bake. While you want the tops of the bars to be firm, you do want the centers to be soft, almost fudge brownie like.
Chocolate graham cracker crumbs replace some of the flour in the recipe; however, you could use regular graham crackers instead. The bars will not be as chocolatey, but they will still work.
Lastly, I used milk chocolate chips, but you can use any chocolate chips you want.
Oh, and one more thing, these are fantastic straight out of the fridge! They taste great at room temperature, but somehow they taste richer and fudgier after being chilled in the fridge.
