S’Mores Oreo Brownies

S’mores and Oreos together? I don’t think dessert could get any better than this!

Smores Oreo Brownie Bars

I honestly considered just posting pictures of this amazingly decadent dessert, because let’s face it, these brownies look freaking amazing.

And trust me, THEY ARE.

Imagine all of the thing that remind you of childhood backyard barbecues and summer vacation all blended together in a fabulous dessert. Sticky S’Mores faces licking the marshmallow off of their fingers, twisting the tops off of the Oreos so you could lick the yummy creme in the center. And brownies. Oh, the brownies.

So I’m sure you want to make these now that you’ve spent the last five minutes drooling over your keyboard. Well they are super easy.

You start with a graham cracker base. Just line a pan with foil and line up the graham crackers, adding broken pieces to fill all the space.

Next you’ll add a cup of marshmallows to the remaining batter and fold them in until they are all covered with chocolate. Then spread that on top of the Oreos. Try to get the brownie batter all the way to the edges of the pan or the Oreos tend to burn.


Then bake that beautiful mess for about 27 minutes, on the middle rack of the oven. Flip on the broiler and sprinkle another cup or so of marshmallows on top of the brownies. Leave them on that center rack and let the broiler brown them for about two minutes. Don’t walk away – they can burn in seconds!



Remove from the oven and allow the brownies to cool completely before cutting into bars. The marshmallow does get sticky so it helps to dip the knife in warm water after each slice.
