Ingredients You Need for OMG S’more Cookie Bars

S’more Cookie Bar Recipe

unsalted butter
brown sugar
granulated sugar
eggs
vanilla
all purpose flour
graham cracker crumbs
baking powder
salt
3 Giant Sized (7 oz each) Hershey’s Milk Chocolate Bars or 4 large (4.4 oz.) chocolate bars
marshmallow fluff

Instructions How to Make OMG S’more Bar Recipe

Preheat oven to 350 degrees.
Lightly grease or spray with cooking spray a 9-inch x 13-inch glass baking pan and line it with parchment paper, so the paper hangs over the sides a little. Set pan aside.
In a separate bowl, whisk together the graham cracker crumbs, flour, baking powder, and salt and set aside.
Using a mixer, in a large bowl, mix together the softened butter, white sugar, and brown sugar for 1 ½ to 2 minutes.
Add in the eggs and vanilla and continue mixing until well incorporated and smooth.
Add in the dry mixture into the butter / sugar mixture. Beat to incorporate, just until all the ingredients come together.
Gather the dough into a ball and divide dough into 2 balls.
Take one of the balls and spread out into the prepared pan by smooshing it down so that it covers the bottom of the pan completely in an even layer.
Cover the dough with a single layer of the chocolate bars. 3 fits nicely.
Next, add the marshmallow fluff to the top of the chocolate bars and spread out to sides of pan.
Lightly flour a board or counter top and smoosh or roll with a rolling pin, the other half of the s’mores cookie dough and make it/roll it the size of the your pan. I do it by placing the pan on top to get an idea about the size to get an idea. Slice the dough into strips and lay each piece on top of the fluff until you’ve covered it all as good as you can. Try to cover up all the marshmallow as good as you can, but it’s ok to have some marshmallow poking out.
Place pan into your preheated oven and bake for about 30-35 minutes, until the top is golden brown.
After baked, transfer to cool completely on a rack.
When cool, slice and serve. Place any leftovers in sealed container.

S’more Bar Tips

These are better served and stored at room temperature. This keeps the marshmallow in tact and gooey. The chocolate does not harden and the cookie stays soft.
Use parchment paper to lift them completely out of the pan to cut them after they have cooled with a stainless steel spatula or a very sharp knife.
They taste great the next day and the next day after that…after that I don’t know. I was held hostage with these until the kids finally had a chance to come over and take them away. Thank Goodness!
You get 28 bars out of a 9×13 pan, which is a decent slice size and these are wonderful for parties and getting smiles.

More Candy Bar Ideas

I used 3 – 7 oz. Giant Sized Hershey Milk Chocolate Bars for this recipe however, other bars you could use besides the Hershey bars, are Symphony Bars, Hershey’s Giant Cookies ‘N Creme Bars, Peanut Butter Cups or Nestle Crunch Bars or anything else you want to fill your candy bar layer with.

Storing and Serving OMG Smores Bars

These gooey bars can be stored in an airtight container at room temperature for about 2 to 3 days.
Serve the bars at room temperature or you can briefly heat in the microwave the make the marshmallow extra gooey and the chocolate layer melty.

In conclusion, OMG S’mores Bars are the perfect combination of gooey marshmallow, rich chocolate, and buttery graham cracker cookie layers. Not only are they a delicious treat, but they also bring back memories of cozy campfires and summer nights.

With just a few simple ingredients and steps, you can turn a traditional campfire treat into a decadent OMG S’mores bars and with this easy s’more cookie bar recipe, you’ll have a perfectly delicious s’mores treat in no time.
