S’mores bars are so easy to make. I love this recipe. They are so rich and decadent that you don’t need to eat a big piece. If you’re taking them to a party, they will feed many people.

I love s’mores. A campfire just isn’t the same without them. Years ago, we were in Gatlinburg at a cabin rental and made a small campfire. I bought all the ingredients, including graham crackers, marshmallows, and Hershey chocolate bars.

Would you believe that was the first time my husband ever tried s’mores? Needless to say, he was hooked and we have them all the time, and we even make them when we have a fire in the living room fireplace.

And these are the perfect s’mores bars for a crowd.

Recipe and printable instructions listed below.

Crust

Start off by adding the graham crackers to a large bag. I used about 1-1/2 sleeves to equal two cups of crushed graham crackers.

You can use a Cuisinart to crush the graham crackers, but if you don’t have one a bag will do the trick.

Make sure you get most of the pieces crushed. It only took me a couple of minutes to get everything completely crushed.

Picture of graham crackers and butter

Add the crushed graham crackers and melted butter to a greased 9″ x 13″ dish. Mix the crackers and butter until it looks like all of the crumbs have butter on them.

Spread the crackers and butter into the dish and press them down flat. I used the bottom of a measuring cup. Anything flat will work to press the crumbs down.

Place the dish in the fridge or freezer so the butter and crumbs will harden a little bit, which will help when spreading the cookie dough.

Mix everything together until it is well blended.

The next step is to add the flour, salt, and baking powder to the bowl. Once you add the dry ingredients, mix everything together for a minute or so, until the ingredients are well blended.

Almost done – add the chocolate chips, so you’ll have chocolate flavor throughout the s’mores cookie bar.

Last but not least, add the marshmallows to the bowl and mix together.

Gather your toppings. I used about a handful of the Cinnamon Toast Crunch Cereal, as well as two Hershey chocolate bars, and about 1/2 cup mini marshmallows.

Next, sprinkle about 1/2 cup of marshmallows on top of the dough.

Finally, press the Hershey chocolate bar pieces down into the dough a tad. You can lay a few of them on top. They will amazingly keep their shape for the most part.

Bake the oven baked smores bars for about 45-50 minutes, or until the cake tester comes out clean. It seemed like I was having to cook it too long, but it was still pretty gooey on the inside, so I kept in going in increments of five minutes toward the end.

If the top seems like it’s getting a little too brown, but the inside is still gooey, turn the oven down to 300-degrees and bake for five minutes at a time until the cake tester comes out clean.

Once the smores bar recipe is done baking, allow it to sit and cool for about one hour. These are a bit like blondies, and let me tell you, they are sooooo delish. And my kitchen smelled like an ice cream shop while they were baking and it was nice.
