Enjoy all the flavor of classic s’mores without the campfire with these incredible s’mores brownies! Fudgy brownies, marshmallows, and graham crackers all baked up into one decadent dessert.
For another easy smores dessert try these 4-ingredient s’mores crescent rolls.
When you can’t decide what to make for a dessert, reach for this s’mores brownie bars recipe. Trust me, it is out of this world! The chewy marshmallows in the brownie mix is my favorite part.
Main Ingredients Used
Chocolate | You can use milk chocolate chips or broken up chocolate bars for this. The chocolate you stir in mixed with the cocoa powder is going to elevate the flavor of these brownies to a whole new level.
Marshmallows | I used large marshmallows that I cut in half. I love the larger pieces of marshmallows in these brownies. Now, you can use mini marshmallows if you would like.
Graham Crackers | Take your graham crackers and break them into pieces. Leave larger pieces so when you bite into these brownies you can taste the buttery graham crackers.
How to Make Fudgy S’mores Brownies
Combine | Start by working on your homemade brownie batter. If you don’t want to make a homemade brownie you can reach for a box. But trust me the homemade brownie is worth the bit of extra effort.
Mix | Mix in the marshmallows and graham crackers. Then transfer into your prepared baking dish. You want to toss just enough so items are incorporated. Don’t overmix.
Bake | Bake your brownies until edges are crispy. Cool completely before slicing.
Variations To Recipe
- Use boxed brownies instead of making homemade.
- Add in some chopped nuts like pecans for added crunch.
- Sprinkle some marshmallows on top right before the brownies are done baking and then let them get golden brown for more of a s’mores look.
- Double the recipe if you want to serve a crowd. Use two 8″ pans or one 9″ x 13″ pan. If using one larger pan baking time will have to be increased.
- Pair with a big scoop of vanilla ice cream for a truly decadent dessert!
What makes brownies fudgy vs cakey?
The biggest difference is for a fudgy brownie you have a higher fat to flour ratio used. Now for cakey brownies, they use more flour and baking powder.
This recipe makes fudgy s’mores brownies. I thought the fudginess worked well with the marshmallows and graham crackers.
Can I make these brownies Gluten-Free?
Absolutely! Use a gluten-free brownie recipe or mix, and then reach for gluten-free graham crackers or cookies to replace the classic graham cracker. Just make sure you use a recipe for your brownies that you know works.
Or you can replace the flour with a gluten-free flour mixture if it converts like regular all-purpose flour.
