Ingredients You’ll Need
- Graham Crackers
- Butter, melted
- Brownie mix (8×8 size)
- Chocolate chips
- Marshmallow cream or a Bag of marshmallows
- Ingredients to make brownies according to the package directions
Step-by-Step Instructions
1. Build the Graham Cracker Base
Start by lining the bottom of an 8×8-inch baking dish with graham cracker squares. You can break or trim them slightly if needed to make them fit snugly. Brush the crackers with melted butter, which adds flavor and helps them stay crisp under the brownie layer.
2. Mix the Brownie Batter
In a large mixing bowl, prepare your brownie batter according to the package directions. If you want to bump up the chocolate flavor, stir in a teaspoon of espresso powder or a handful of dark chocolate chips. Pour the batter evenly over your graham cracker crust, then use a flexible spatula to spread it into a smooth, even layer.
3. Add Chocolate and Bake
Sprinkle chocolate chips across the top of the batter before baking. Follow the bake time on your brownie mix until a toothpick inserted in the center comes out with moist crumbs. Let the brownies cool for about 5 minutes before moving to the next step.
4. Toast the Marshmallow Layer
Once baked, switch your oven to low broil. Top your brownies with mini marshmallows or a layer of marshmallow fluff. Broil on the top rack, at least six inches away from the heat, for just 1–2 minutes, until the tops turn golden brown and slightly melty. Watch closely! Marshmallows go from toasted to burned in seconds.
If you’ve got a kitchen torch, this is the perfect time to use it for precise, evenly toasted tops.
5. Cool, Slice, and Serve
Let your brownies cool on a wire rack for at least 10 minutes so the marshmallow layer can set a little. Then slice into squares with a sharp knife coated in nonstick spray or lightly oiled; it’ll help you get clean cuts through that sticky, gooey top!
Storing and Reheating
To keep your brownies soft and fresh, store them in an airtight container lined with plastic wrap or parchment paper, separating the layers with plastic wrap or parchment paper. You can also freeze individual squares for up to a month, just thaw and warm slightly before serving so the chocolate gets melty again!
Frequently Asked Questions
Absolutely. If you’ve got a favorite homemade brownie recipe that’s rich and fudgy, use it instead of a boxed mix. Just make sure it fits a standard 8×8 pan.
Nope! Mini marshmallows, or even large ones cut in half, will work perfectly. The cream just gives a smoother, spreadable layer. If you have any leftovers, you can also whip up a batch of Chocolate Cookies with Marshmallow!
Yes! Double the recipe for a 13×9-inch pan. Just keep an eye on the bake time; thicker layers might need a few extra minutes.
Pop a square in the microwave for 10–15 seconds to bring back that gooey s’mores texture and melty chocolate.

Mmmmm! The “crisp’ peeled off easily & the underneath tastes great! No scorched taste at all! Happy that I didn’t have to throw it out & waste the $$. sure looked bad, but yummy!
wowowow! My broiler must be lots different than most! After 10-15 seconds I smelled what reminded me of burning marshmallows at a campfire & yikes mine were literally flaming. I quickly put them on the patio table (outside) & then a nearby crow started “laughing” at me! Luckily, the smoke detector was in a different room so that wasn’t a problem too! I may be able to salvage them after scraping the “black char” off them, but oh well. I had my broiler on low & the rack was as low as it could go! Hmmmmm? Maybe “toast” them in the oven next time! 🙂 Thankful I didn’t have to call 911!!!
I love the brownie recipe& I love people shining. ….true colors

wreck. You’re shiny heart is glowing all the way up here
in good ol’ West Virginia Mountaineer Country. …and I love it!
You’re always my favorite country cook & the inspiration YOU give is
priceless. Love ya…. and that sweet lil family of yours as well.
Thank you so much for your encouragements Christy.. I to have constant pain from arthritis eating up the bones in my feet. It is very difficult to walk and is constant pain. Your words have let me see that I still need to shine and not be a pain for those around me and for myself.
Your site is one I read all the time..

i was just thinking today i wonder how she is, i bet there is still pain but she’s not complaining about it. i prayed for you. i hope you will continue to heal and that the pain will go away. meanwhile THANK YOU as always for being a bright light of encouragement and a wonderful example and reminder to look for the good in everything!
Thank you so much for your prayers Meridith!
I will look at the brownie recipe in a few (know it will be fabulous), but had to stop and comment after reading your thoughts on shinning. I so love and appreciate you for sharing your encouraging articles. They really make a difference in my life and the lives of others as I share copies with those around me when applicable. I struggle with being upbeat and happy when life throws curves my way but my desire is to be more like you. Your articles help me focus on that and reminds me to keep on keeping on. I thank God for the healing He has provided for you and pray for His continued blessings on you and your family. Thank you from the bottom of my heart!
Made these last night…so glad I wasn’t going for bloodwork this morning, LOL! Between the melted butter, the extra chocolate chips ( Yup, the only brownie mix I had on hand was ‘double chocolate’ with chocolate chips in the batter, and you know I followed the recipe as written and added chips on top of the batter..hee hee! ) and the marshmallow cream, these were well over and way beyond the top! The salted butter with the graham crackers reminded me a wee bit of pretzels and was a nice contrast to the sweetness. My daughter’s Girl Scout troop would flip over these! I promised my daughter Erin, that I would make them for one of our upcoming meetings- one which I will NOT be attending, because I really don’t want to be there after these brownies bring on the inevitable sugar rush and ensuing craziness that this troop is known for…God love ’em! Thanks for the inspirational message and a great recipe. You are awesome!
