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

Description

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


Ingredients

  • 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)

Instructions

  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. Okay these look amazing! I love all the other different variations of 7 layer bars you have too! I have only ever made the most basic of 7 layer bars but if those are good these have to be fantastic!

    1. You can’t go wrong with the traditional version – I love those! Let me know if you try any of my variations sometime. Thanks Nicole!

  2. I grew up eating magic cookie bars and I make them pretty regularly. I just made an almond joy version recently and halved the recipe because any bar like this is my guilty pleasure! Your s’more peanut butter version looks crazy good, and I’m so glad I have a gym membership! I love that you put crunchy peanuts on top too!

  3. I love magic bars too, but I have never tried making anything other than the regular variety. This must be changed!

  4. I almost put PB 7 Layer Bars in my cookbook but went with a golden yellow cake base rather than the graham cracker base. But pretty much the sweet cond milk, choc chips, marshmallows….all there. Great minds think alike 🙂 I loveeeeee 7 Layer Bars and could go to town on the 8×8 pan, but good job for downsizing it from the 9×13 usual size. I have tons of recipes for half-cans of sweetened cond milk. I could put that to use very easily 🙂 The look delish, Sally! Totally my thing!

    1. oooooh a yellow cake base! I’m so intrigued. I can’t wait to see those! I knew you’d love these – you’re the bar queen. So many wonderful recipes for them on AC.

      1. Averie,
        I just made this recipe by Sally and was wondering if I should just toss the remaining 1/2 can of condensed milk…then I saw your comment about having tons of recipes for it! Could you name a few? I don’t think I can use “1/2 can condensed milk” as a search term!
        Thanks! Love both of your blogs, ladies!

      2. Hi Stephanie! Here are my recipes using 1/2 can of condensed milk: https://sallysbakingaddiction.com/2013/01/05/caramel-snickers-7-layer-bars/
        https://sallysbakingaddiction.com/2012/11/07/apple-butterscotch-magic-seven-layer-bars/

    2. I use extra condensed milk to make my own coffee creamer. About equal parts condensed milk & evaporated milk makes the perfect sweetener + creamer, no extra sugar necessary in your coffee. Although it doesn’t hurt to add some choc or caramel syrup to the mix 😉 … The small 5oz can of evap milk is perfect for the 5-6 ounces you have left in that can!

  5. MM seven layer bars! I used to hate them when I was younger because most people put coconut in. Now that I am older and wiser I know the bars do not require coconut 🙂 I love the peanut butter twist on smores and with all the condensed milk.. gaaaahhh I just want to bathe in condensed milk! I don’t think thats normal.

  6. Just looking at these makes my teeth hurt. I can’t imagine how delicious they are! Way to combine two of my weaknesses, s’mores and peanut butter! Sheesh

  7. Holy awesomeness. I need to make this stat! And I love that this doesn’t require a mixer!

  8. Totally making these and doubling the recipe.. Ohhhh man my husband is going to hate me because he just started a diet and isn’t going to be able to resist these (hehe).

  9. Hi Sally

    You mentioned in your headnotes, next time you make these bars you will add more peanuts. How much more?

  10. “S’moregasbord” indeed…..S’MORGASMIC…to boot!!!.

    Between this and getting caught in a teensy weensy elevator with a shirtless Hugh Jackman..I would decidedly be hesitant to choose!

    Your creativity concerning ALL of your layer bar combinations STUNS…as does the forever superlative photography.

  11. Let’s be honest– you had me at s’mores… but OMG these look AMMMMAZING. Cannot wait to make them. Like, maybe tonight. 🙂

  12. I just bought a hard-to-find bag of vegan marshmallows thinking, “I just know Sally is going to tempt me into using these ASAP”. You didnt dissapoint 🙂

  13. My seasonal allergies have been so bad, I haven’t baked a thing in weeks! I’m going into withdrawal…. maybe this will bring me out of my funk. I still need to make the chocolate chip cupcakes with the chocolate chip cookie dough frosting. Damn sneezing, stuffy nose…. can I have one of yours in the meantime?;)

  14. I need to make this for my next family gathering. All of them love and adore peanut butter. Since I am weird and don’t like peanut butter, I might replace the peanut butter with some butterscotch chips and eat the whole batch myself! Heh heh.

  15. I haven’t made 7-layer bars in forever … but I am loving this peanut butter s’mores version! Peanut butter, yes! S’mores, yessss! Wouldn’t mind having one of these for breakfast right now either haha but that would be bad : )

  16. Yum! I’ve made your 7-layer snickers bars a few times, so I’m excited to try this version!

  17. Good lord, girlfriend.. you’re insane! But I mean that in the most sincere way possible! Only an insane person could think to make peanut butter s’mores seven layer bars. OH MYLANTA INDEED! They look SO gooey.. that picture of you pulling the marshmallowy chunk away .. heaven!

  18. These look AMAZING! I have been craving s’mores a lot recently, so I’m glad I have most of the ingredients on hand because these will be made this weekend!

  19. The addition of cream cheese or marshmallows is about the onyl way peanut butter and chocolate gets any better. Love these.

  20. Man, these 7 layer bars are popping up everywhere lately and I love it! I’m gonna have to jump on the bandwagon and make these tasty bars this weekend. My fats pants are going to love you.
