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

Peanut Butter S'more 7 Layer Bars

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

Yield: 12 bars


  • 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 350F. 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 love your site! Every time I need a special recipe for a party or get-together this is the first place I go! (You had me AND my friends hooked after I used your amazing peppermint patty cookie bar recipe for santacon last xmas…)

    These will be perfect for this afternoon’s sunny day bbq! Thanks Sally!!

    1. Hi Sam! Sounds like a fun BBQ ahead. This recipe may easily be doubled to fit a 9×13 pan – however, I am unsure of the baking time. Just keep your eye on them. Enjoy!

    1. Hey Lauren! so glad you follow my blog here and on Pinterest. Thank you! You have to try these 7 layer bars. So easy to make!

  2. Made these and they are yummy! Didn’t even add the pb cups or peanuts and they were still easy and delish! Next time, I will add more marshmallows. Thanks, Sally!

  3. So…just made these, need some tips. The marshmallows got kind of hard, they also turned brown pretty quickly, I was cooking on convection at 350 so don’t know if that is why, basically I think I overcooked the whole batch…my kids liked them but they were a bit crunchy and again, marshmallows were hard, recommendations, what did I do wrong? Thanks! I’m a peanut butter lover so am hoping to make these again!

    1. Hi Nancy! I’m going to suggest reducing the temperature down to 325F. Sometimes when I bake in a convection oven, I find that the tops of my cookie bars, brownies, etc brown quicker due to the heat circulation. Try covering the pan loosely with aluminum foil too. And you know what’s helpful too? Immediately after you pull them ou t of the oven, sprinkle with a few additional marshmallows. They will melt down because of the warmth of the bars and still be soft when the bars cool off.

      1. So, my second batch came out much better, I used regular setting vs. convection setting on my oven for 350, I covered the bars after 10 minutes as that’s when they started getting brown, then took them out after total of maybe 35 minutes, yum, these were so good! I think next time I make them I will use the mini mini reese’s cups, think that will be better than big reese’s cut down which is what I did originally. Next project, onto the snickers caramel layer bars which you have here!

  4. These look amazeballs! Especially being 8 months pregnant! However, this page is not showing the recipe? I need this recipe! Is there a way to fix it (for others to try as well) or please email it to me?!

  5. Thanks for another fabulous (as always!) recipe. My husband and I made them last night for our Easter celebration, and I just ate one for breakfast ;). xox

  6. These are amazing! Sally, you inspire me…. I used the crust from your Ultimate 7 layer bar (switched out the butterscotch chips for peanut butter chips and 2 T peanut butter for the butter) and they were wonderful. The substantial crust holds up to all the delightful toppings and the marshmallows made it look pretty – little puffs of toasty sugar! Thank you. It’s a wonderful holiday treat (but no holiday required!) 

  7. I think it was awesome making them with my mom because it was quick , easy , and fun. Also can’t wait to try and taste them.  Praja age 10 

  8. Hi!! These look so good, and a girl at work had them made, so of course now I have to make them! 
    Ive been wondering how you think adding a brownie mix to the bottom would work? Think it’s worth trying? 

  9. omg! amazing! I think the marshmallows on top really made the dish stand out! Forgot the peanuts so I cut up some walnuts and the bars were still heavenly! Thanks again! I’m bringing these to a halfway house my small group is serving at and I know these will be a hit! Thanks for the recipe!

  10. I made these for a party this weekend and they were a hit…so yummy! However, mine did not look as nice as yours. I did double the batch and make them in a 9×13 pan, so maybe that had something to do with it. I also left out the peanuts for full knowledge. But you couldn’t see all the individual chips like I can in your pictures. It was more like everything melted together. They still tasted great, but any hints on how to make them look nicer? I baked them for the same amount of time as the smaller recipe and actually covered them towards the end because I felt the marshmallows were getting too dark.

    1. Hi Stephanie, I’m glad they were a hit! The peanuts would have changed the look a bit, and also after this comes out of the oven I sometimes sprinkle a few extra chips on top purely for looks!
