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!

S'mores Fudge Bars is a fudge recipe and smores recipe all in one!

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.

Smores Fudge BarsHow 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!

How to make Smores Fudge Bars

  • 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!

  1. Has anyone tried making these in a mini cupcake pan? Just wanting to try it so I dont’ have to cut, lol! I’ve made them once already and they were adored by all! Thanks for the great recipe!

    1. Not sure what happened to yours, but the homemade fluff recipe should be thick, and creamy, just like int he pictures. Can you explain what your results were?

  2. I’ve made these a bunch of times now and they’re always a huge hit. My only problem is the marshmallow fluff is very sticky and I make a huge mess when I slice up the finished product. I normally place the individual bars in cupcake tins to store so they don’t stick together. Any tips on how to make the fluff easier to work with?

  3. I just made these! OMG!! They are fabulous. I followed the recipe exactly except I used semi-sweet chocolate morsels. I’m not sure why you need to line the pan with foil but I did it anyway. Marshmallow frosting is divine. Don’t use store-bought……homemade is best. Also, I make my graham crackers from the cookie. I put them in a plastic ziplock bag and crush them with a rolling pin. Don’t ziplock the bag so air can get out

    1. I have had people ask me this and have tried it on their own and it works! It might not cut as pretty as the homemade version, but it will taste good!

  4. How sticky is the marshmallow? I was thinking of wrapping them up in parchment or wax paper for goodie bags.

    1. It’s a little sticky. If you let them sit out at room temperature for a bit they will firm up and be wrappable!

  5. Made these for some friends and everybody LOVED them! Normally I’m indifferent towards marshmallow, but this homemade fluff was incredible and easier to make than I thought it would be. 10/10 will definitely be making again!
