During the summer, one of my favorite things to make as a kid was s’mores. While I like a good bonfire, I LOVE the fact that I can have this quick and easy Homemade S’mores Brownies dessert any time of the year.
These easy homemade s’mores brownies start with our grandma’s famous Fudgy Brownies as the base, but then are layered with toasted marshmallows, graham crackers, and chocolate squares to make the perfect s’more dessert.

Ingredients in Homemade S’mores Brownies
- Unsweetened cocoa powder
- Butter
- Granulated sugar
- Eggs
- Vanilla extract
- Flour
- Salt (I used unsalted)
- Miniature marshmallows
- Graham crackers
- Hershey’s candy bars
*Pro tip: If you don’t have Hershey’s candy bars available, you could substitute chocolate chips.
Equipment Needed
For this recipe, you only need a few simple kitchen tools. We recommend using the following equipment:



How to make S’mores Brownies
- Preheat oven to 325℉.
- Grease a 9 x 13 inch baking pan.
- In a small saucepan over medium heat, melt butter. Once butter is melted, stir in cocoa until smooth. Pour into a mixing bowl.
- Then add in sugar and eggs to the mixing bowl and stir together.
- Add in vanilla, flour, and salt and beat together well.
- Spoon batter into prepared pan.
- Bake 25 to 28 minutes, or until cooked through.
- Remove pan from oven and top with marshmallows, graham crackers, and candy bar pieces. Place pan back in oven and cook for 2-3 more minutes or until marshmallows start to puff up and chocolate pieces start to melt.
- Allow brownies to cool completely, then cut into squares and serve.
Storage Suggestions
If you manage to have any leftover Bars + Brownies, these can store well if prepped appropriately. Once they have cooled completely, here is how you can store it:
- Counter: Store bars and brownies in an airtight container at room temperature for up to 4 days. If your kitchen is particularly warm, consider refrigerating instead to prevent them from getting too soft or melty.
- Refrigerator: Place in an airtight container and refrigerate for up to 1 week. Let them come to room temperature before serving for the best texture and flavor.
- Freezer: To freeze, make sure bars and brownies are completely cooled and unfrosted. Wrap tightly in plastic wrap (or Press & Seal) and then place in a freezer-safe bag or container. For easier portioning, wrap individual squares before freezing. Don’t forget to label with the date. They’ll stay fresh in the freezer for up to 3 months.
Can I used a brownie mix from a box for this Homemade S’mores Brownies recipe?
Definitely! Brownies from a box will work perfectly in this recipe. Just make sure that the brownie mix is for a 9×13″ pan.
Follow the directions on the box of brownies and bake as directed, then pick up on the step of the recipe where you add the marshmallows, graham crackers, and Hershey’s chocolate pieces on top.
How to cleanly cut brownies
These brownies are GOOEY and can be really hard to cut! Here are my tips to getting a nice, clean cut.
- Let the brownies cool completely before you try to cut them. Cutting warm, gooey marshmallows is only asking for a mess. If you don’t care how the brownies look, feel free to cut into them while they are still warm. But if you want a nicer, clean edge, resist the urge and let them cool down.
- Use a plastic serrated knife. I know that it sounds crazy, but it works!
- Spray your knife with non-stick cooking spray (or your choice of grease). Just spray both sides of the blade before making a cut. After each cut, wipe the knife clean and re-spray.
- Dip the knife in hot water before making each cut. Clean off the knife after each cut and then dip it again in the hot water. It will help make every cut smooth as butter!
