Some days you just want an ooey, gooey s’more. Today? Is one of those days.

S'more Blondie Bar Recipe - blondie bars topped with Nutella and toasted marshmallows! The BEST indoor s'mores!

On the ooey, gooey, chewy front, we had something BIG happen last week. Big! Huge!

Jordan got her braces off!!!! (You can see her pretty smile here.)

She’s had her braces for about 2 1/2 years. (She’s 10, if you’re keeping track.) She got them years before all of her friends and she got them off just as they’re all starting to get them on. That’s because (1) we have really big teeth and really small palates and (2) she sucked her thumb for about 5 years.

{When she stuck her thumb in her mouth at 4 months and finally stopped crying I was elated. 6 years later at the orthodontist? Not so much.}

S'more Blondie Bars

As I’d promised her, we went to this fabulous Willy Wonka-esque candy store for lunch that day. She picked out a pound of various jelly beans, taffy, caramels, and gummies. I’m letting her go hog wild on chewy things until Wednesday when she gets her permanent bottom retainer. (Such a buzzkill.)

And then in about 2 years we’ll get to do it all over again…with phase 2. (Again…total buzzkill.)

One thing she could always enjoy, even with braces? S’mores.

S'more Blondie Bars

Because it’s well established that I don’t do outdoor s’mores, I make indoor oven s’mores. I don’t even like making s’mores in my backyard, so the oven is it for me.

“No, child of mine, love of my life, we never ever play with fire. Never get too close! Never light a match! Fire is BAD!”

“Sure honey, go stick that long flammable tree stick in the fire. Be sure to catch the marshmallow. Lean over the fire, why don’t you?”

Me and fire aren’t friends.

Me and s’mores are friends…when I can broil the marshmallows in my oven.

Oh, and when the s’mores are on top of a blondie and instead of regular chocolate you use Nutella.

Nutella for S'more Blondie Bars

Yes, that. I bought Nutella for you guys. See what sacrifices I make for you?? (Because now I have a jar of Nutella that I’ll eat with a spoon.)

Okay so let’s break down these bars.

The blondie base is my favorite blondie recipe. It’s a basic recipe that you can do so many things with. In fact, I’ve use this same exact recipe to make Loaded Chocolate Chip Bars, Caramel Crunch Blondies, Toffee Blondies, Butterscotch Gooey Bars…and so on.

The blondie is full of butter and an extra hefty dose of brown sugar. The 2 full cups of brown sugar makes these stay soft for days. And, well. 2 cups = good. You can make the bars a few days ahead of when you’re going to make the s’mores without any issue.

(If you don’t want to make these s’mores blondies – why not?? – you can use this base recipe with any number of mix-ins. Use your favorite candies!)

Once the bars are cool, don’t cut them. Slather them with Nutella instead. Or, if you don’t have or like Nutella (!!!) you can use any chocolate spread you want. There are so many kinds out there now; Hershey’s and Reese’s both have a version. Or use peanut butter!

Sprinkle the top with mini marshmallows and then broil them for just a few minutes. Don’t walk away from the stove! You don’t want them to burn. Cut and serve the s’mores bars that day, if possible. Marshmallows go wonky once they’ve been heated and left to sit overnight.

So, to recap: the best blondies ever, chocolate, and gooey marshmallows.

Or, as I call it, breakfast.

Okay fine. Not breakfast. Lunch! 🙂

Did you make this recipe?

S'mores Blondies

The best basic blondie recipe is topped with chocolate spread (Nutella) and toasted mini marshmallows for an ooey gooey indoor s’more!


  • 1/2 cup unsalted butter
  • 2 cups brown sugar, packed
  • 2 eggs
  • 1 tablespoon vanilla extract
  • 1/2 teaspoon salt
  • 1 teaspoon baking powder
  • 2 cups all purpose flour
  • 1 cup Nutella or other chocolate spread
  • 4-5 cups mini marshmallows


  1. Preheat oven to 350°F. Line a 9×13” pan with foil and spray well with cooking spray.
  2. Mix butter and brown sugar with a stand or a hand mixer until crumbly. Mix in eggs and vanilla until smooth. Mix in salt, baking powder, then flour. The mixture will be wet.
  3. Spread in prepared pan. The mixture is wet so it’s best to spray your hands with cooking spray and then smooth the dough with your hands to get an even layer.
  4. Bake for about 22-25 minutes until they start to turn golden. Err on the side of under baked with these – they’ll finish baking as the cool and you don’t want them over baked. Cool completely before continuing.
  5. Frost with chocolate spread and top with marshmallows. Broil on high for about 1-2 minutes, watching them closely to make sure the marshmallows don’t burn. Once you add the marshmallows, these are best eaten the same day.


You can use any brand chocolate spread you like: Nutella, Hershey’s, Reese’s. Or you could even try peanut butter!

  1. Okay, I’m terrified of fire. So much so that once I was making penne a la vodka and when the pan caught fire, I just screamed. A lot.
    My son was a thumb sucker too (until we literally hired a “thumb lady” to detox him), so yep, we’re facing years of orthodontia. Congrats on being done with phase one!
    These bars look magnificent.  And much better than cooking over an open flame [insert scream of terror here].

    • I would have screamed too! I hate fire!! And good luck to him, she had it bad before even the thumb. Thank goodness they do two phases now; I had to have 4 adult teeth pulled when I had mine!

  2. Aw, Jordan must be so happy to get her braces off! I had mine for 13 months and I remember the first thing I ate was an apple; the best apple of my life! Smores bars look amazing, especially with the nutella. I love making smores by fire however, we make them indoor in winter with our fire as in the summer, it is too windy for a campfire in Scotland! 

  3. I love the flavor combination with the blondie, nice change of pace.

  4. Jordan must be so excited to be free from braces. I had mine for almost four years during high school and it was the worst. I love the idea of oven s’mores. I’ve never tried them. My family’s motto is “It isn’t a party until something catches on fire”…It’s actually pretty terrifying. We’ve had a plastic decoration turkey catch on fire, part of our couch due to a candle being too close, and my dad’s leg at a graduation party! Yeah. Lots of fire in my life. I’d rather have s’mores any day!

  5. Nutella, blondies, smores…I think you just put the holy grail of desserts into one recipe!

    Congrats to Jordan for her brief respite from orthodontia. What a cross for her (and you $) to bear!!

  6. Whoa, these look seriously delicious, and I say that as someone who doesn’t even really like S’mores – there’s something about marshmallows cooked over a campfire that makes my throat itch, but I’m hopeful that this indoor version won’t have that effect! I feel for Jordan. I had two phases of braces as well, and still lament over how many summers of corn of the cob I missed out on.

  7. Those bars look amazing!  I love the blondie base, what a great way to make s’mores even better!  And I totally agree with the fire thing, we DO roast marshmallows with the kids to make s’mores but I’m a complete paranoid basket case the entire time, always feeling like someone is going to fall in the fire or fling a flaming marshmallow!

  8. Have I been following you that long?   I remember when she got them on!  Time goes so quickly!

  9. Wow this look good!!  I really enjoy smore’s–they make me think of summer!!  I am a total nut case when the kids are around an open fire–just so afraid someone is going to fall in!  Congrats to Jordan for getting her braces off!!  I think we will be heading down the braces path soon with out oldest!  Not something I am looking forward too. 

  10. You need a microwave S’mores maker. We got one several years ago on QVC. They are wonderful! They marshmallows PUFF up and I mean PUFF up! I like putting a Reese’s Peanut Butter cup in mine.

  11. Oh my gosh, I love this. I love everything and anything s’mores!

  12. Yummy! How sweet 😀

  13. Yay for Jordan getting her braces off for phase one.  I remember all the foods I missed when I had to wear mine but I could never keep away from s’mores either. These blondies look incredible! Love the Nutella!

  14. Smores totally take me back to my childhood! These blondies look amazing, Dorothy! I love the toasted marshmallows on top. Pinned!

  15. I had braces really early too! Such a distant memory now. I won’t be forgetting these blondies though! Awesome as always, Dorothy!

  16. I think these totally work for breakfast!

  17. The day those braces come off is one of the best days of your life! I also have a permanent retainer (on my bottom teeth) and it was one of the best decisions I’ve made. Now that the braces are off, bring on the sticky and chewy sweets!! 🙂

  18. Love the chocolate, marshmallowy gooey-ness of these!

  19. You knocked this out of the ballpark but then again, since when do you not do that? Adore these!

  20. You are the best mom ever to take her to get all that candy! Luckily baby Stella hasn’t started sucking her thumb yet…and she doesn’t have teeth to ruin just yet but I am sure we will be headed to the orthodontist someday anyway lol Loving these S’mores blondies! Nutella is my favorite thing ever, I am totally with you on eating it with a spoon! 

  21. WOW! These look amazing! I am not a big fan of real s’mores either. Is it just me or is there too much graham cracker and not enough chocolate? These, on the other hand, look like they have plenty of chocolate. Plus I’m sure those blondies are not dry like graham crackers! Yummy yummy!

  22. SO GOOD! I’ve used Nutella before to make s’mores…best.thing.ever! 

  23. Oh my goodness Dorothy, I’m drooling over these right now. Blondies, smores and nutella – These sound amazing!

  24. That thumb sucking always catches up on people. We’ve got like three kiddos in our family with braces written alllll over them. The candy lunch is worth it in my book though! 😉 Me and smores are best of friends, that gooey marshmallow is just SO good. And the Nutella?? Not.even.fair. Need these asap!

  25. I love a fire roasted marshmallow, but a s’more with nutella and a blondie, total game changer!

  26. I can’t even get over how amazing these look. Adding Nutella into the mix sounds like THE best idea ever!

  27. Oh my lanta…mad craving for these s’mores blondies–they look insanely amazing!! And with Nutella? just yum! 
    And major congrats on your daughter getting those braces off! After 4 years of metal mouth, my braces coming off was one of the most freeing days of my life! She’s gotta feel awesome! 

  28. I love everything s’mores related. I always need a new excuse to make them!

  29. Getting my braces off was such a highlight! I’m sure she is so happy! Aaaand I love that these s’mores are baked bars! I once singed my hair at a campfire (I was never meant to be a girl scout) so indoor s’mores bars is a safe bet for me, haha! Anyway, these look bomb, Dorothy. Straight bomb. 

  30. These look amazing!  I love s’mores, blondies and nutella…these bars are a triple threat!  And, I’m about to get baptized by fire soon as we enter the world of braces in our house….

    • Good luck Ramona! It’s a rocky start but then they barely notice them anymore, except at Halloween. Have lots of non-sticky candy ready to trade for all those tootsie rolls!

  31. I am dying these look so good . . and Jordan is such a doll!!! you’re going to have the boys a knockin’!!!! 

  32. When don’t I want a s’mores?  There is something about those gooey marshmallows and chocolate that gets me every.single.time!!!  I love that you added Nutella to blondies to make s’mores!  And braces…ugghhh we just got the first child out of them.  I’m just dreading the dentist telling us it is time for the second one to get them!  Stinking thumb sucking children…I mean that in the most loving sense of the words 🙂

  33. Yum! These are the ULTIMATE. I am mega crushing on those gooey toasted mallows on top! 

  34. oh wow this looks absolutely amazing! I love anything s’mores related!


  35. omg, smores with Nutella – I die! The bars look amazing! And so fun for Jordan to get her braces off. I never had them, but my brother had to do the two rounds and my parents never made him do the second. It doesn’t look fun. So glad she’s getting a break from them!

  36. I love s’mores, and I love Nutella even more.  And the two together?  Count me in!

  37. These are to-die-for! Love the toasty marshmallows!!

  38. Yayyyy Jordan! I got my braces on and off young too–sucks that she still has phase 2 though 🙁 Her teeth look great already!

    These blondies look sooo insanely chewy and gooey and I mean…nutella….s’mores….what’s not to love!?

  39. Anything S’mores is just magical. I love these blondies.
