If you like peanut butter and you like s’mores (who doesn’t?!), then you will flip for my latest concoction. You see, I have a bit of an obsession with making 7 Layer Bars, which are also called “Magic Bars” or “Holly Dolly Bars”…or just plain “awesome.” Whatever you call them, layering a ton of chocolate, marshmallow, peanuts, and Reese’s on top of a graham cracker crust is always a win in my book.

With an apple version and a Snickers version, I knew a s’mores version would fit in nicely.

Today’s recipe is so incredibly easy. That’s the main reason why I love to make 7 Layer Bars: they hardly require any skill or thought. You’re literally throwing a bunch of items on top of each other into a pan and baking. Between moving and planning the wedding, I’m all about easy baking these days. No mixer required, no multiple bowls needed, no extra dirty dishes. Easy peasy.

Brainstorming these bars, I thought of all the flavors that make up a s’more. Graham crackers: those will be the crust. Chocolate: that will be the first and most important layer. Marshmallows: those will get nice and toasty on top. What will make up the rest of the layered dessert though? Peanut butter quickly came to mind as I thought of nice pairings for a s’more dessert. I love peanut butter s’mores.

The peanut butter comes in two forms: mini peanut butter cups and peanut butter chips (morsels). Yep, you’re getting a double dose of peanut butter. Would you expect anything less?

I used Reese’s mini peanut butter cups, the same kind I used to decorate my Peanut Butter Cupcakes with Dark Chocolate Frosting. You could also simply chop up a few regular Reese’s peanut butter cups instead.

The last two additions are peanuts and sweetened condensed milk. Peanuts are optional, but I loved the extra crunchy texture they gave each bite. If I made these again, I’d add even more peanuts! The sweetened condensed milk, however, is necessary. It is what will bind all of your other peanut butter s’more-y stuff together.

This recipe is for a small batch of 7 Layer Bars, made in a 8×8 size baking pan. Traditional recipes are made in a large 9×13 pan, making about 24-30 squares. Going over to a friends house for double date night, we didn’t need so many. Although Kevin did ask me if there were any leftover bars the next day. There was not. Today’s recipe may easily be doubled if you’re making for a large family, party, or get together. It’s helpful to note that this recipe, because it’s small, does not use an entire 14 oz can of sweetened condensed milk – only 8 ounces. However, if you’d like to double this recipe and make it in a 9×13 pan, you may use a standard 14 oz can and double the rest of the ingredients.

Look at all that marshmallow goo. Peanut Butter S’more 7 Layer Bars, can I eat you everyday? You’d certainly help me get the most out of my gym membership.

The sturdy graham cracker crust is a s’moregasbord of tempting flavors and textures. You’ve got your crunchy peanuts, melty chocolate, smooth peanut butter chips, creamy peanut butter cups, and ultra gooey marshmallow madness. It’s heaven in bar form.

I’m telling you – these bars are SO easy to make! If you know how to pour things into a pan, you can make these. If you have tastebuds, you’ll like these. If you’re a s’more freak, you’ll LOVE these. What are you waiting for? #gimmesmore

  • Author: Sally
  • Prep Time: 15 minutes
  • Cook Time: 35 minutes
  • Total Time: 3 hours
  • Yield: 12 bars
  • Category: Bars
  • Method: Baking
  • Cuisine: American


7 layers of s’more and peanut butter goodness. This dessert is dangerously simple to make!


  • 1 cup graham cracker crumbs (about 6 full graham crackers ground up)
  • 1/4 cup salted butter, melted
  • 1 cup semi-sweet chocolate chips
  • 3/4 cup chopped Reese’s Peanut Butter Cups (I used chopped up mini Reese’s)
  • 1/2 cup peanut butter chips
  • 1/2 cup salted peanuts
  • 1 cup mini marshmallows
  • 8 oz sweetened condensed milk (a little more than half of a standard 14 oz can)


  1. Preheat oven to 350°F (177°C). Line 8-inch or 9-inch square baking pan with parchment paper or aluminum foil. Spray generously with non-stick spray. Set aside.
  2. Stir together graham cracker crumbs and melted butter. Mixture will be relatively crumbly. Press onto the bottom of the prepared dish and slightly up the sides. Layer chocolate chips and next 4 ingredients (in that order) into prepared baking pan. Drizzle with sweetened condensed milk.
  3. Bake for 35-38 minutes or until center is set. Allow to cool completely and lift the bars out of the pan using the ends of the parchment. Cut into 12 squares. Bars stay fresh at room temperature for 1 week.

  1. I really don’t know if I’d have the patience to wait for them to cool. Double the peanut butter is just waaaay too exciting! I’m obsessed with 7 layer bars and this combo sounds absolutely fab!

  2. These look so fantastic! I love those little mini peanut butter cups. And those little peanut butter chips. And the chocolate. And, oh, well, just everything!

  3. now this is my kind of 7layer bar! i love smores flavor. love..thanks for sharing your new creation.

  4. s’moregasbord<—I see what you did there! And #gimmesmore. You are so clever. And brilliant! S'mores are my favorite, so of course they would go wonderfully with peanut butter! I mean, what DOESN'T go well with peanut butter? I'm thinking chocolate or honey Teddy Grahams would be a good topping to add some crunch and texture if people didn't want to add peanuts. Then it'd almost be like a peanut butter s'more sandwich. Ugh, now my mouth is watering.

    1. I LOVE that idea of teddy grahams on top. Now I’m kicking myself for not doing it. Guess I have to make them again!

  5. Sally, I think I’m in love with these bars! You just combined all of my fav ingredients into one delicious treat. Yum!

  6. So much peanut butter goodness! I love the ease of 7 layer bars too! And I actually think that there is something very pretty about bars covered in different kinds of “chips” and candy 🙂 Yummy!

  7. Wow! These sound amazing… I love the traditional 7 layer bars and I’m sure I would love these as well. I’ll have to try these as soon as I round up the ingredients! Keep up the great recipes!

  8. Love magic bars and the addition of the peanut butter is fantastic. You know me Sally, you can never go wrong with peanut butter 🙂

  10. Mmm, isnt melted marshmallow just the best?! And I love how easy these little ones are to make! Yum 🙂

  11. I always know I’d better be ready for something amazing when you start writing “oh my lanta”! 😉 These look absolutely fabulous. I don’t like nuts, so I think I would do Golden Grahams or maybe those marshmallows like the kind in hot chocolate…. The photograph of the stretching marshmallow is great…nice capture! 😀

  12. Oh my! These look insane, Sally! I love making easy bars like these… better yet, I love EATING bars like these! We must be on the same brain wave. Cz I made some PB bars last night to put up next week…and I had to hurry and give some away so I wouldn’t devour the whole batch! These PB Smore 7 layer of goodness looks dangerously delish!

  13. So….gooey…and…chewy…mind officially blown. And no mixer? Sally you’re a girl after my own heart. 😉 With final papers and projects I could use a simple sweet treat like this!

  14. i must have more than 9 lives cuz i die each time you post a new goodie. my printer has already died a few times too printing up all your recipes. LONG LIVE SALLY!!! heehee

  15. Good morning from the Milwaukee airport! These look awesome and will be my next sba undertaking. Just FYI the skinny blueberry banana muffins turned out beautifully. I gave most away as one of the acts of kindness but I kept 3 and they are so good. Happy Friday! Xoxo

    1. I’ve been to Milwaukee before Katy! My company’s headquarters is there. 🙂 And yes, I went to the Miller Brewery before! Loved it. Happy Friday! Safe travels. 🙂

  18. slkdjfasdfjide! I’ve been rendered speechless by the amazingness of these bars. I need to make these stat!

  19. I mean, I just have no words for these bars Sally! Other than, I cannot wait to make them and bring them into work as a treat!

  20. First of all, my best friend from college always says “Oh my lanta” and I’ve never heard anyone else say it before until now! Also, ummmm…these bars. I can’t even take it. I don’t even want to try to make them healthy. I just want to eat them just the way they are.

    PS: Have you ever heard of Charlie Brown bars? I had one at a Whole Foods last summer, and it was so incredible. I spent weeks trying to find a recipe online with absolutely no luck, and I can’t get them out of my head. I figured if anyone would know it would be my favorite bar queen. 🙂

      1. That’s the problem–I have no idea what was in it. I just assumed I’d be able to google it, but now I’m afraid I’ll never know! If I ever figure it out, I’ll let you know 🙂

  21. Magic bars are some of my favorites too because of how easy and gooey and delicious they are!!! You had me at peanut butter and then you said s’mores and I knew I was in love with these bars!! They are full of all my favorites…I would love to eat them every day for the rest of my life!

  22. I very much have to find those crackers in a gluten free version. I’ve seen these kind of bars that have the SCM poured over them a few times and I would love to try this recipe out. Looks extremely tempting as always. 😀
