Smores Fudge Bars

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!

Who loves Smores?

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!

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!

DO NOT USE BROILER if you have an old oven that is unpredictable. Almost had a oven fire! Got lucky and only the marshmellow layer burst to flame!

These are my go-to for Summer treats, and to take to neighbors. They are worth every bit of time and mess involved. Mine come out perfectly every time. If you are a S’mores lover, these are for you!!!

Mine turned out just okay. I think the crust needs more butter. Mine was a crumbly mess and didn’t stick together. The fudge layer was stiff and hard to spread. The marshmallow layer didn’t get stiff enough so when I cut them into squares they just oozed everywhere. My kids loved them but they were a little too sweet for me and I’m a sugaraholic! Haha!

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!

Hi I am from England what would I use for corn syrup please ?

Jul 14, 2017 12:44 pm

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?

Jul 2, 2017 5:06 pm

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

Could you use store bought marshmallow fluff instead of homemade?

Oh my gosh. These are absolutely sinful. DELICIOUS. Thank you for an amazing recipe.

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

Oct 31, 2016 11:43 pm

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!

Sep 13, 2016 6:38 pm

Hi there! Do you think these would be mailable? Thinking of making them and sending to a friend!

I’m making these for a BBQ on Friday, so I’m planning to make a recipe and a half. At the end of the recipe she talks about storing the extra fluff – do you think there is enough extra fluff for another half a recipe?

I took these to a women’s Bible study tonight and everyone thought they were incredible! I loved how fun it was to make marshmallow fluff from scratch!
