What’s not to love about decadent melted chocolate and ooey gooey marshmallows? This S’mores bars recipe is seriously so indulgent and amazing. If you love s’mores as much as we do, this is a must try along with S’mores Cookies and S’mores Cones.

Why We Love this Recipe

  • Easy 5 Ingredient Recipe – All you need to make these easy bars is graham cracker crumbs, marshmallows, butter, brown sugar and Hershey Chocolate Bars. No baking powder and salt is needed.
  • Simple Process – All you need to layer the ingredients and then roast marshmallows.
  • Easier than Campfire S’mores: There is no need to make a campfire to make these s’mores bars. These s’mores bars make enough to feed a crowd.
  • Full of Flavor – We love that every bite is full of chocolate, graham cracker and marshmallows.
Ingredients for recipe - graham cracker crumbs, marshmallows, brown sugar, butter, chocolate bars.


  • Graham Cracker Crumbs. You can crush graham cracker sheets or buy premade crumbs.
  • Brown Sugar. Try some of The Best Brown Sugar Substitutes.
  • Mini Marshmallows. The large marshmallows are harder to serve on the bars. I recommend the mini marshmallows.

Variations and Substitutions

  • Change the Chocolate – Use peanut butter morsels and semi sweet chocolate chips to make peanut butter and chocolate bars. This creates a delicious chocolate topping!
  • Peanut Butter Layer – Create a peanut butter layer by mixing in peanut butter morsels to make a peanut butter base in these bars. This is perfect for peanut butter fans and goes great with milk chocolate chips. We have even just used Reese’s peanut butter or natural peanut butter. 
  • Chocolate Topping – Try using dark chocolate for the chocolate topping. That is also tasty.
  • Marshmallow Creme – You can use marshmallow creme if you prefer, but we like the way the mini marshmallows melt under the broiler.
  • Crust. Substitute crushed Golden Grahams Cereal in this recipe.

How to make S’mores Bars

  • Step 1. Prepare the oven – First, preheat oven to 350 degrees.
  • Step 2. Grease the pan – Next, grease the 9×13 pan with non-stick butter spray.

Expert Tips

  • Use Warm Knife – The s’mores bars can get really sticky to cut. Warm a sharp knife under hot water and dry it off and immediately slice them. This should help making cutting the bars easier. 
  • Graham Cracker Crust – You can also use graham cracker sheets and a food processor to make your own graham cracker crumbs. I usually do whichever one I can get cheaper when I happen to be making these.
  • Baking Dish – This recipe is perfect in a 9×13 baking dish.  It really makes the s’mores bars the perfect thickness. You can also a square pan for a thicker bars.
  • Line Pan with Foil – You definitely want to line your pan with foil. The chocolate and marshmallows can get a little sticky and messy. The foil will help make clean up much easier.
  • Use Disposable Pan – Now, I will tell you another tip that I often do if I really want zero cleanup. I often use disposable pans. It’s nice to just be able to toss the dish. Just do what works best for you.

How to store?

If you have leftover S’mores Bars, store them in an air tight container at room temperature. To reheat them, place them in a microwave safe plate and heat for about 10 seconds.

How to freeze?

Yes, you can freeze these s’mores bars. In fact these delicious bars freeze really well. Place leftover S’more bars in a freezer safe container. They will stay fresh for up to 2 months.

Once you are ready to serve again, just set them out and let them reach room temperature.

Can I use different chocolate?

Yes, you can. We used the traditional Hershey’s Milk Chocolate mini bars but you can definitely use what you have. Here are some we recommend

Mini Peanut Butter Cups
Hershey’s Chocolate Kisses
Dark Chocolate
Mini Snicker Bars
Hot Fudge Syrup or Caramel Syrup
