These Smores Fudge Bars are one of my most favorite treats! This easy Smores recipe is a version of the campfire treat that you can enjoy all year long, with a graham cracker crust, a sweet and silky chocolate filling with a fluffy, toasted homemade marshmallow topping!

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!
AND you guys all love these bars so much they were one of the recipes I included in my book from my website! There are only a few recipes that made the cut, and these did.

I saw this recipe on Facebook and had to make it. It was a lot of fun to make and I always enjoy making marshmallow fluff. I followed the recipe exactly, and I personally found these to be waaaaay to sweet. So much so that I’m considering throwing them out rather than taking them to a fourth of July party. Next time I attempt this I’ll probably cut out the sugar or some of it from the crust and I’ll definitely cut the condensed milk in half. Thank you for the idea and the beautiful pictures!
If you used graham crackers with sugar on them already then it would definitely be overly sweet. When they were first done I wasn’t sure I could tolerate the sweetness, but after a second taste and everyone’s emphatic approval I, too, became please with the result.
Does the marshmallow fluff cook enough under the broiler for just a minute? I’m a little concerned about the egg whites not being cooked enough.
When you pour the warm sugar mixture into the egg whites it cooks them!!
I was going to make these before realizing I am out of Foil, can I use something else or some mad non stick spray
You could use parchment!
Oh my goodness gracious Shelly!! These are insane!
Made these yesterday! Amazing! I increased the butter to 1/2 C. I had never made marshmallow before and it turned out great! Everyone loved it! Definitely will make this again and pass it along to friends!
Thanks so much for fabulous photo walk-thru of your recipe! Can’t wait to surprise my hubby with these! I’m going to try it with dark chocolate chips. 😉
I did a test run of this recipe today. I am hoping to make them again for an event in two weeks. I didn’t have a 9×9 pan, so I used a 13×9. I increased the graham crackers to 2 packages (of a box containing 3 packages, or about 2 1/2 cups) and I used 2 tablespoons more butter. It didn’t occur to me to increase sugar or salt since I was mostly worried about covering the bottom of the pan, and I wouldn’t add any more sugar next time either. Maybe the salt though. It turned out nicely thick and held together. I didn’t have any problems with the fudge layer, but I was wondering if there is a way to get this layer to cool more solidly (temper it?). I might look into that next time. I had a little bit of a problem with the fluff layer. I have this habit of reading directions literally to the point of abandoning what I already know about cooking. Haha… So, when it said, “drizzle the syrup along the side of the bowl slowly combining it into the egg whites”, I did it slowly… and what happened, of course, is that the syrup began to form candy chunks and strings throughout the marshmallow mixture and a mound of candy began forming and cooling onto the side of the bowl and entangling in my beaters. :/ Next time, I will pour it at medium speed. I also think that I will reduce the vanilla a little and maybe the sugar in the syrup too. Despite losing so much syrup, it was still so, so sweet. Very delicious and mostly easy to make.
Has anybody tried that with real marshmallows? I would love to do it and I could this way for my husband and kids, but I’m allergic to eggs, so was curious to see if anybody has tried before I do! 🙂
Suzie, I make homemade marshmallows all the time, and the recipe I use has no egg at all. It calls for unflavored gelatin. The recipe I use calls for four packets, some call for three, both taste the same, just different sizes. They are so good! Google “homemade marshmallows recipe using gelatin” and you’ll be in business! To make fluff instead of the marshmallows, beat for about 7-8 minutes instead of the full amount of time. Hope this helps!
Would it be blasphemous to make it with dark chocolate? Has anyone tried that yet??
Lady I swear you and I are soulmates! Ok maybe kindred spirits ( as we are both married;) everything you make is exactly my favourites and always so scrumptious people ask me for recipes. I’m sure these are no exception and can’t wait for a lil marshmallow fluff crack 😉
