S’mores Fudge Bars Are Treat All Year Long!
I am a HUGE smores fan! And in all honesty, I fancy myself a bit of a smores connoisseur…which, in fact, is my birthright. Did I tell you I was born on National Smores Day? Yep. It’s in my DNA. And of course, I have so many smores recipes here on my site, like S’mores Cheesecake!
And since I try and get my smores fix any which way, I created these Smores Fudge Bars that are all the flavors we love in smores, but OH SO MUCH MORE! You have a rich, silky fudge filling, on top of a thick graham cracker crust, all topped with Homemade Marshmallow Fluff, which is so dreamy!

What Are S’mores?
Let’s start at the beginning, in case you aren’t familiar with s’mores. Can you believe I have met people who have never had s’mores? I don’t know why this is so mind boggling to me, but it sure is. I suppose if you didn’t grow up in the US, or Canada it hasn’t always been a universal treat.
S’mores are campfire treats that generally consist of a toasted marshmallow and a piece of chocolate sandwiched between two graham crackers. Of course I take tons of liberty when making s’mores by the fire. My favorite combo is two Ritz crackers, a peanut butter cup and a toasted marshmallow. It’s salty/sweet perfection! BUT in keeping with tradition, these S’mores Fudge Bars are all the classic flavors.
S’mores Fudge Bars Are An Easy Fudge Recipe!
How to Make S’mores Fudge Bars
For these s’mores fudge bars, the steps are all easy. You just have three different layers to create!
- First you make your graham cracker crust, which is a simple graham cracker crust recipe, just graham crackers, butter, sugar, and salt. You bake that up until it’s lightly golden.
- Next up make your chocolate fudge filling, which only has two ingredients, milk chocolate and sweetened condensed milk. You melt sweetened condensed milk and milk chocolate together to form a thick, but pourable chocolate fudge. Spread this on top of the crust!

Next you make your homemade marshmallow fluff! Once you make this homemade, you will never buy the store-bought again!
- You just beat egg whites and some cream of tartar together until soft peaks form.
- Next, make a sugar syrup in a saucepan with corn syrup, sugar, and water. You will need a candy thermometer here to make sure it comes up to 240°F. This guarantees the thickness, and firmness of the fluff.
- In the bowl of your stand mixer fitted with the whisk attachment, you slowly pour the syrup into the egg whites, while mixing. Once it’s all added, beat that for 7-8 minutes until it’s thick and glossy!
- This recipe makes a lot, and you can use it all on your fudge bars, or spread a thinner layer on top and save the rest!

- Spread the marshmallow fluff on the chocolate with an off-set spatula and then pop it under the broiler, just for about a minute until it gets a little brown on top…
- Please watch closely as it broils, because it can go from lightly toasted to burnt QUICKLY!

Allow the bars to cool completely before slicing into pieces, and then enjoy!! I love fudge recipes, and this S’mores Fudge is deliciously unique!

These were going to be awesome but on the broiling step I opened the oven to find the whole pan on fire. Very scary put it out with fire extinguisher. Just posting so people know this can happen . It was probably at a minute and a half broiling because top wasn’t browned at one minute. All is well but dessert is ruined and house smells like campfire. I really can’t believe I didn’t think of the possibility of this catching on fire given that I’ve roasted marshmallows over campfire my whole life. Careful people!
That happened to me today! I just ended up blowing out the fire, scrapping the burnt part off and remaking the marshmallows and it was perfect.
Hey I love this recipe and want to make it. But is there a replacement for cream of tartar, corn syrup and graham crackers? because these arent sold where i live
I almost hate to ask this, but could you feasibly use Marshmallow Fluff instead of the home made fluff? I’m not a big fan of the whole “get sugar super hot, then pour it into something” plan. I usually end up injured….
hahaha! well sure, you can. It might not slice up as smoothly, as the fluff might ooze a bit, but it will work!
I uses 4 egg whites instead of 2 and used chocolate sweetened condensed milk instead of plain. It was yummy
The ingredients and procedure for marshmallow are the same in making a cake frosting???
The marshmallow ingredients and procedure look like a cake frosting?
Very similar!
Love this! Makes me feel like a kid again.
That is a traditional 7 minutes icing on top, I think I will try marshmallow cream when I make it. It would be more like real marshmallows.
So I made this and found the crust crumbled because it wasn’t wet enough, and found the chocolate layer too rich. I did however love the marshmallow layer!!! I think I’ll try about half the amount of chocolate and add more butter to the crust next time.
I made these for Easter and they were a huge hit. I got multiple requests for the recipe. They are perfect just as they are. They are pretty rich, but super fun.
