Seriously, is there any dessert better than s’mores? Well, I wouldn’t be able to choose between a S’more and a Chocolate Chip Cookie.

So, in the event that I’m ever forced to choose between two unbeatable dessert options, I’ve come up with a fail-proof plan: these S’mores Cookie Bars!

I have a plethora of delicious dessert options ranging from the simple to the (almost) complex.

But, like many other people, we can get stuck in a rut enjoying the same recipes over and over.

Chocolate chip cookies are always requested and enjoyed. S’mores, on the other hand, tend to be a summertime delight.

So you can imagine how delighted I was when I came up with this super easy S’mores Bars recipe. It is GENIUS!

This recipe is so easy that you actually no longer have to choose which favorite dessert to make. You also don’t need a campfire to achieve the delightful s’mores flavors.

Plus, if you’ve ever tried the Starbucks s’mores bars, you know how amazing they are (and how quickly the cost to feed that addiction adds up)!

Make these s’mores bars yourself – it’s SUPER easy!

WIN, WIN!!! 😂

Take this recipe to your next potluck, and you’ll be the start of the show!

S’mores Bars Recipe Notes And Tips

  • After removing them from the oven for the final time, you can chill them in the refrigerator to help cool them down a little quicker.
  • This recipe calls for mini marshmallows, but if you only have regular-sized marshmallows, use them. You can cut them in half if you prefer.
  • If you do not have parchment paper available, aluminum foil will work just as well.
  • Allow your S’mores Bars to cool completely for easier slicing.

Variations Of S’mores Bars To Try

  • A mint chocolate bar will add a little extra added zip to those delicious bars.

Here are some common questions I see readers ask about these S’mores Bars…and their answers.

How do I store any leftover S’mores Bars?

IF you have any leftovers, they will keep for up to 5 – 6 days at room temperature if stored in an air-tight container.

Can I freeze S’mores Bars?

Absolutely!!! They can be frozen for up to 6 weeks if stored in a freezer-safe, air-tight container. Allow thawing at room temperature before serving.

Can I make these S’mores Bars ahead of time?

Yes! If you are taking these to a family reunion or school function, you can certainly make them a day ahead of time and store them in an air-tight container until you are ready to serve.

Can I double this recipe?

You bet!!! You will just need an extra parchment-lined baking pan!

Can I use marshmallow creme or fluff instead of marshmallows?

That would be a great choice since the fluff or creme stays soft and gooey even when not warmed up. But beware because it can be very sticky and messy!
