A gooey milk chocolate, marshmallow center is sandwiched between two layers of soft graham cracker crumble in these Soft Chewy Smores Crumble Bars! All the magical flavors of a traditional S’more but even more delicious!
Lisa over at Wine and Glue is hosting S’mores Week and I am beyond excited!! I love S’mores inspired desserts and these Soft Chewy Crumble Smores are no exception!
These bars will takeover your life! You will dream about them. You will never be satisfied with a regular s’more again! Just a hunch. Let me break them down for you:
A soft, buttery graham cracker crumble bottom is topped with a layer of marshmallow fluff…
Then a smooth and creamy milk chocolate ganache is poured on top…
Then it’s topped with more graham cracker crumble and mini marshmallows.
The chocolate ganache melts in with the marshmallow fluff in the oven, which creates a perpetually soft, chocolaty, marshmallow center to these Chewy Smores Crumble Bars. It almost replicates that texture that you get when you bite into a campfire smore and the gooey marshmallow mixes with the partially melted chocolate.
Only better because the graham cracker sandwich outside is soft and chewy. Secretly I think the crunchy graham cracker that crumbles all over the place is the worst part of the S’more. Nobody wants a mess. Especially if you aren't actually camping.
When you bite into one of these soft bars all the magical, familiar s’mores flavors blend together into one cohesive taste explosion.
A touch dramatic but these bars are seriously that delicious! You will LOVE them!
And if that isn’t enough to convince you, these bars got RAVE reviews. In fact, one guy told me that I should sell each tiny bar for $2. Thank you random guy on the 30th floor, you made my week. Seriously. The whole week.

Recipe
Soft Chewy Smores Crumble Bars
Ingredients
For the Crumble Base & Topping:
- 1 cup unsalted butter (room temperature)
- 2 ¾ cups graham cracker crumbs
- 2 tablespoons graham flour (you can also use whole wheat flour or all-purpose)
- ¾ cup sugar
- 1 large egg
- ½ teaspoon baking powder
- ¾ teaspoon kosher salt
- ¾ teaspoon pure vanilla extract
For the Remaining Layers
- 4.5 oz milk chocolate (high quality, I use Ghirardelli)
- 2 tablespoons heavy cream
- 6.5 oz jar of marshmallow fluff
- ½ cup mini marshmallows (or more to your taste)
Instructions
Make the Crumble Base & Topping:
- Preheat the oven to 350° and line an 8” x 8” baking pan with parchment.
- Whisk together the graham cracker crumbs, graham flour, salt, and baking powder in a medium bowl and set aside.
- Beat butter and sugar together in the bowl of a stand mixer on medium-high speed until fluffy, about 2 minutes.
- Reduce the mixer to medium speed and add the egg, mixing to until well combined, about 2 minutes. Add the vanilla and mix until combined.
- Reduce the mixer to low and add the dry mixture in several additions, scraping down the sides of the bowl as necessary.
- Scoop ⅔ of the mixture into prepared baking pan. Spread out evenly with an offset spatula. Bake in preheated oven for 15 minutes or until the top is beginning to brown and the sides are set. Cover the remaining mixture and refrigerate until ready to use.
- Allow to cool while you prepare your ganache.
Prepare Milk Chocolate Ganache:
- Combine chocolate chips and heavy cream in a microwave safe bowl. Microwave on 50% power in 20 second intervals, stirring between each, until the chocolate has melted and is smooth. Let cool slightly.
Assemble your bars:
- Spread the marshmallow fluff on the prebaked bar base using an offset spatula. A warm spoon will help get the fluff out of the jar and onto the bars with minimal mess. I coated my small spatula in butter before attempting to spread the fluff. Worked like a charm!
- Rinse off your spatula and pour the thickened ganache over top of the fluff. Spread evenly with your offset spatula.
- Remove crumble topping from the refrigerator and crumble over the top of the ganache in small crumbles. Sprinkle on the desired amount of mini marshmallows over the top.
- Bake in preheated oven for 20-30 minutes or until the crumble topping and marshmallows have begun to brown.
- Allow bars to cool completely before cutting and serving. If you don’t, it will be a hot mess!
We've made these a couple times and realized the first time that the butter listed in the recipe must be double! It was absolutely sopping with it - a massive puddle at the bottom of the pan! The second time we used 1 stick instead of one cup and it was perfect!
HI Kleo! I'm glad you gave it a second shot, and that you enjoyed!
These look A-Mazing! I'm definately going to make these goodies! Would they still be yummy made the day before serving or are they best out of the right out of the oven. I'm having a big party this weekend, whatever I make for dessert will have to set for a while...
Hi Melissa! You are going to love them!! I actually thought (and so did my taste-testers whose bars lasted that long) they were even better the next day. I stored them covered at room temperature. They were still soft and moist on day 3 and 4...after that, well, there were none left! If I were serving them at a party, I would make them the day before but not much sooner than that. 🙂
Thanks for getting back to me! Can't wait to make them!
You are most welcome! Have a wonderful party!
I think soft chewy trumps crummy graham crackers any day!
A woman after my own heart!
Oh my gosh! Could these bars be any more perfect?! Seriously, I want every single of those luscious layers. Gorgeous gorgeous photos! Pinned!
lol thank you!!! You are so sweet!
well....you've done it. ALREADY all I can think of is these bars-they look sooo buttery and gooey and just AHHHH YUM!
They do overwhelm the senses and it is impossible to get them out of your head! Trust me, I've tried!
These bars look amazing! I'm drooling over that layer of chocolate ganache!
Thanks, Cristin! You can never go wrong with chocolate ganache!
Just saw them on Google +.. I fall in love with them.. I can imagine the taste..... mmmmmm.... mouthwatering..
Thanks, Ella! They are so soft - I just can't even deal! If they were here right now...there is no telling how much damage I would do!

Wow, these look delicious and the must taste fantastic if people are telling you to sell them. Maybe you need a bakery 😀
They are sensational but I don't think I could handle running a bakery!
Wow! These look way better than an actual smore!
haha! I think so 😉
It's only 8:30 in the morning and I really want these bars! They look utterly decadent and I could probably finish a whole pan off in 5 minutes!
That was certainly a possibility in my kitchen too! I kept sneaking bites during the photoshoot...just could help myself!

Now you'll just have to make them!
These look amazing and addictive Lindsey! That guy is right - you could sell them! But, why would you? More for you if you don't! 🙂
lol! you are right (as always)!! Better to hoard them and spend more time at the gym 😉
Hooooly moly these look awesome!!! I love s'mores everything and these look so so right up my alley. Pinning, and definitely not letting my summer end without trying these!

These look amazing! I love s'mores and bet these are even better!
Thanks, Kristine! They are sooo amazing! I had to regift immediately! My brother saw your Cherry Crisp Ice Cream when he was here and he was smitten!
Whoa! I will give this recipe to my teenager - she and her friends would love it. Thank you!
They definitely will!! This would have been a HUGE hit at any high school girl gathering back in my high school days! 🙂
