S’mores Fudge Bars

Growing up, s’mores were part of nearly every summer gathering. Whether a picnic at a local park or around a campfire in the Rockies, my mom would pack the requisite graham crackers, marshmallows and Hershey bars. We looked forward to the fire dying down so we could make those ooey, gooey sweet marshmallows sandwiches.

But to be truthful, I would have rather eaten a couple graham crackers and half a chocolate bar. As an adult, I was thrilled to discover s’mores desserts. Now these I cannot resist! S’mores cookies, pies, even dips along with these incredible S’mores Bars recipe are delicious twists on the classic campfire dessert.!

Layered S’mores Bars Recipe

This is my monthly recipe swap from with my sweet friend, Danielle, of Hugs & Cookies. I found this s’mores bars recipe on her blog and knew it would be a hit. A  huge hit in fact! I upped the butter in the crust as Danielle suggested in her recipe, but otherwise made it as written. My “fluff” wasn’t stiff enough to make  peaks and swirls, but they still received a bevy of compliments!

This classic American flavor profile would be a magnificent treat for Memorial Day, the Fourth of July or Labor Day. But I wouldn’t wait for a holiday to make these gems.

Tips for Making these S’mores Fudge Bars:

  • The marshmallow topping is made with egg whites. PRO-Tip: When you whip egg whites, your utensils must be scrupulously clean or the meringue will not get white and fluffy. Make sure your bowl and beaters do not have any traces of oils and if even one speck of egg yolk contaminates the whites, they will not whip.
  • PRO-Tip: Use a hot dry knife to cut these bars. The topping is sticky and the heat will help the knife “melt” its way through.
  • Reheat your knife once it stars sticking again. I run it under my hot water dispenser, then wipe it dry with a towel.
  • You can purchase graham cracker crumbs, but you can also make them at home by breaking up graham cracker squares and running them through the food processor. The latter is more economical, too!

Be careful when adding the sugar syrup to the egg whites as it is extremely hot.

Watch your pan carefully when it's under the broiler so your topping does not burn.

  1. Toasted s’mores are so irresistible! I’m with you, I won’t really eat them on their own, but on these fudge bars they look too delicious to not eat them!

  2. I can’t believe they cut so nicely for you! The one time I topped a pie with marshmallows… Let’s just say I think there’s still some marshmallow super-glued to the knife! That fudge layer sounds really good too… I’m off to check out your pie now:@)

  3. These look so beautiful and marvelous. Stunning pictures as always. I can only imagine how delicious they taste.

  4. Perfect timing on these s’mores fudge bars as I am sitting at the cottage typing this comment—I know this recipe would fast become a family favourite for sure. I love the flavour of toasted marshmallow but the other two layers would certainly put it over the top for me. And the bonus would be that you won’t become a sticky mess like you do with the traditional s’mores.

  8. I hope you had a happy Mother’s Day, Liz. I do love the perfect layers of this snack. We didn’t grow up eating s’mores and in fact, I only heard about them when I connected with a few US bloggers. I’m yet to sit around a fire pit and eat a s’more! xx

  29. These bars look wonderful, what a great treat!!

  31. This sounds amazing! I wonder if you could use actual mini marshmallows and just melt them on top? I don’t have cream of tartar and don’t really want to buy it as this is probably the only time I’d use it.

    • Hi, Randee, I think that could work. I’d chill the bars (or even freeze for a short time) before trying to brown the marshmallows so the fudge doesn’t melt all over the place 🙂

  32. I made these to take to a 4th of July cookout today. They were a hit with everyone. Thanks for the great recipe!
