Peanut Butter S'mores Bars
One of our favorite family activities is sitting around a campfire sharing funny stories and looking at the stars. Of course, toasting marshmallows to make s’mores is always a must.
Since moving to Florida, we've had very few backyard fires. The warm weather isn't ideal for bonfires, so we haven't roasted anything over a flame in a while.
So, I’ve been on a mission to bring those gooey, chocolatey vibes indoors. These s'mores cookie cups and s'mores brownie cupcakes are some of our favorites to make in the kitchen. But when it's summer, I'm all about no bake desserts.
My s'mores bars have a crunchy yet chewy texture with a nutty peanut butter twist. They are basically scotcheroos made with Golden Grahams, and yes, they are incredible! Ready in just minutes, these treats will be the hit at all your summer parties.
Main Ingredients
You only need six simple ingredients to make these cereal bars. They have the classic s’mores flavor with a creamy, peanut buttery flavor!
- Granulated Sugar: Sweetens the mixture even more.
- Corn Syrup: Mixes with the sugar to create a sticky syrup that holds everything together.
- Peanut Butter: We prefer the creamy spread for this no bake treat, but a crunchy variety would also be fine.
- Box of Golden Grahams: You will need one 12-ounce box of cereal. I don't recommend using any other cereal because you'll lose the s'mores flavor.
- Marshmallows: I used miniature marshmallows inside the bars and the tiny bits for decorating the tops.
- Hershey's Chocolate Bar: I cut the candy bars into pieces and freeze them before I do anything else. This stops them from melting too fast in the warm mixture.
BruCrew Tip: Use leftover marshmallows and chocolate in these s'mores recipes.
How To Make Golden Graham S'mores Bars
For the full printable directions, scroll down to the recipe card at the bottom of the post.
Stir together the corn syrup and sugar in a large saucepan. Heat it over medium heat until dissolved, then bring it to a boil.
Remove the pan from the heat and stir in the peanut butter until smooth and creamy.
Add the graham cereal to a large bowl and pour the hot mixture over it. Stir until everything is evenly coated.
Stir in the miniature marshmallows and frozen candy bar chunks quickly and gently.
Press the cereal mixture into an even layer in a prepared pan. Immediately top the warm bars with the remaining candy bars and marshmallow bits.
Storage Recommendations
Keep leftover bars in an airtight container at room temperature for 4-5 days. They will stay soft for days.
Place a piece of parchment paper between the layers to prevent the gooey marshmallows from sticking together.
BruCrew Tips
- Chop the candy bars into small pieces. Place the bowl of chopped milk chocolate bars in the freezer ahead of time.
- Use butter or cooking spray in your baking dish and on your hands to prevent the treats from sticking. You can also line the pan with parchment paper or foil to make it easy to lift the treats out.
- Do not overcook the sugar syrup, or you will end up with very hard treats.
- Press the cereal mixture firmly, yet gently, into the pan. Pressing too hard can make your treats hard and crunchy.
- Add the rest of the marshmallows and chocolate bars right away. This helps them melt a bit and stick to the top of the cereal treats.
- Take it up a notch and stir in frozen mini peanut butter cups instead of chocolate bars.
- Let the treats cool completely before cutting into them. If you cut them too early, they may fall apart. They will still taste amazing, but they won't look as pretty.

Peanut butter just NEEDS to be with s'mores. It helps cut the sweetness of the chocolate, and it is just SO AMAZING with the marshmallow fluff! I love that you used Golden Grahams too - such an underrated cereal for sure! Pinned!! 😀

Yes! I can't wait to sit around the campfire and make s'mores. That is one of my favorite things about summer. But in the meantime, I need to try these s'mores bars. The addition of the peanut butter is perfect!

I love all things s'mores, and I realllly love peanut butter! These are right up my alley! I love slathering a little PB on the graham cracker when I make a regular s'more! PB on graham crackers is one of my favorite snacks anyway! It only made sense to take it a step further and make it a s'more. Haha! These bars look so simple to make too. Thanks for sharing, Jocelyn!
Jocelyn
I will definitely have to try the pb on a regular s'more this summer...that sounds perfect!!!
Aimee @ ShugarySweets

Erin @ Miss Scrambled Egg
Peanut butter and graham cracker make for one happy girl! We had this event at college called Midnight Breakfast. Basically, all of the students would go to the dining hall at 12 AM during finals week and stuff their faces with eggs, pancakes, and french toast. I always went straight for the Golden Grahams. Friends would question my choices, "You stayed up for Golden Grahams." My answer, "Yes, I certainly did." Reliving my college days as well as anticipating summer...count me in!
Jocelyn
I would totally go for the big bowl of Golden Grahams too!!! 😉
Gayle @ Pumpkin 'N Spice
I love the looks of these bars, Jocelyn! Totally makes me forget that it's in the single digits outside. This also takes me back to my childhood of roasting marshmallows. Looks delicious!
Taylor @ Food Faith Fitness
Yes! Whenever we make s'more, I actually always add peanut butter on the graham cracker. You can't take me away from peanut butter and chocolateing all the things.
So these bars? Gimme s'more!
Had to. Pinned!
Jocelyn
Any chance I get to add s'more chocolate and peanut butter, you know I will 😉 Ha! Thanks for sharing girlie!!!
Averie @ Averie Cooks
I've made bars before years ago with Golden Grahams but it's been years. And I love G.G.'s! And with the PB you used. And the marshmallows...omg heavenly! Pinned 🙂
Jocelyn
I just love those Golden Grahams so much, so I'm always trying to work them into something! Thank you so much for the pin love 🙂 You are the best!
