S’mores without the fire

If you love campfire s’mores, but not the hassle of making a fire, I have the perfect treat for you. . . Smores Brownies! These brownies are ooey, gooey, and just tasty as the s’mores you make around the fire. In fact, we liked them even better.

Melted chocolate, toasty marshmallows, and graham crackers on top of a fudgy brownie. It doesn’t get much better than that.

Not only are these brownies absolutely decadent and irresistible, they are super simple to make. Just bake up a batch of regular brownies. I used my favorite brownie recipe for the base, but you could even use a boxed mix. Either way, these decadent treats are going to be a hit. And unlike s’mores around the fire, you can make these any time of year!

how to make s’mores brownies

PREP. Preheat the oven to 350 degrees.

BAKE. Spread batter in a 9×13″ pan that has been lined with foil or parchment paper and sprayed with non-stick spray. Bake at 350 ° for 30-35 minutes or until toothpick comes out clean.

TOPPINGS. Remove from oven and immediately sprinkle with chopped Hershey bars, graham cracker pieces, marshmallows, and chocolate chips. Return to oven and broil for 2-3 minutes or till marshmallows are toasted and chocolate is melted.

Tips + Variations

Chewy or cakey brownies: It is all personal, but for this recipe you may want to go more cakey, just so the brownies can hold up better with the weight of the chocolate and graham crackers on top. If you prefer chewier brownies that would also be great.

Layering matters: In this recipe it’s important that you place the Hershey chocolate pieces on before you add the Graham Crackers and marshmallow. The melted chocolate acts as a glue holding the other two ingredients on. If you add the graham crackers first, then the s’mores topping will not hold to the bottom brownie layer. 

Cutting: The marshmallows are pretty sticky making these a bit tricky to cut. One tip that helps is to spray your knife with cooking oil. 

Jumbo marshmallows: If you just have big marshmallows, cut them in quarters and layer them over the brownies and graham crackers. Also, no matter the size of the marshmallows make sure that they aren’t old for best results. 

How to broil: When you broil something you choose the broil setting on your oven and allow the heat to only come from the top of the oven to toast the marshmallows.


  • Add some chocolate chips into the brownie batter to give it more melted chocolate taste.
  • Crush the graham crackers and sprinkle it on top
  • Use a different flavored candy chip such as white chocolate or butterscotch.

    1. This is a contributors recipe, but it looks like you just use your favorite brownie recipe, then top with all the yumminess & it goes back in the oven for a few minutes. Does that make sense? So, you can even just make a boxed brownie & follow those instructions, before following the rest of the steps for these brownies. Hope you like these?

  1. Can’t wait to make these – more yum missionary treats!! Kristyn, I didn’t see where the oven temp was listed, I’m assuming 350? Thanks,


    1. I did it at 325, for about 26 min, and they turned out great! I guess it would depend on your oven though.

      1. Thanks!! I always have the worse time with brownies!! Either too soft or too hard!! I’ll try what you did!!

    2. Thanks and, yes, more treats!! It’s whatever brownie recipe, you want to use..either homemade or boxed. Hope that helps 🙂

  2. 5 stars
    This looks amazing! Have you ever made it with the graham crackers on the bottom as more of a crust? Do you think it would turn out alright?

  3. 5 stars
