 These bars come together in less five minutes, are virtually work-free, and taste far more decadent and indulgent than you’d imagine something that’s so easy to make could taste. They’d make a great last minute holiday treat for a party. Or make them for a special night with your couch and remote control.

My grandma’s version of these bars, and many similar recipes, use peanut butter. I’m a peanut butter fiend, but also have a soft spot for Biscoff and it’s sweet, cinnamon-ginger pop. I couldn’t resist re-making a childhood favorite with it.

Biscoff Spread, Cookie Butter, and Speculasspasta are nearly interchangeable and in this recipe, use whatever is available. I’m in Aruba, a Dutch island, and used Dutch Speculaaspasta, the Dutch equivalent of Biscoff Spread.

I’m convinced that Speculaaspasta and Trader Joe’s Cookie Butter are the same product, simply labeled differently. Even the glass jars are identical.

Trader Joe's Cookie Butter

To make the bars, combine chocolate chips and Biscoff Spread in a large microwave-safe bowl and melt them. Peanut butter may be used and the recipe will work, but the telltale cinnamon-and-gingery kick will be absent. Adding hearty pinches of cinnamon and ground ginger to peanut butter or almond butter, and a sprinkling of crushed graham cracker crumbs is a workaround, although not quite the same.

To the sweetly-spiced chocolate puddle, add marshmallows, and one cup of chopped Biscoff cookies. Trader Joe’s sells knock-off Biscoff cookies called Bistro Biscuits, or chop two full-size cinnamon-graham crackers. After coating the marshmallows and chopped cookies with the sweetly-spiced warm chocolate, transfer the mixture to a foil-lined small baking pan and smooth it.

I sprinkled a small handful of chocolate chips over the top both for texture contrast and to boost the chocolate intensity, not that these thick bricks were lacking in the chocolate department.

Allow the bars to set up for at least two hours in the refrigerator before slicing. Freezing the pan is acceptable if you’re in a rush like I always am. I store the bars in the freezer here and they never really freeze solid. When it comes to dense or dark chocolaty treats like brownies or rich bars, chilling them makes even more satisfying. Plus, chocolate begins to melt the minute it comes into contact with the warm, humid Caribbean air.

The recipe is ripe for substitutions based on what you have on hand and enjoy. Add slivered almonds, macadamia nuts, or a handful of shredded coconut to the batter. Omit the Biscoff cookies or graham crackers and instead use Nilla wafers or chopped Oreos. Sprinkle white chocolate chips, cinnamon chips, peanut butter or butterscotch chips, toffee bits, diced peanut butter cups, or Rolos on top. Mix and match until your heart’s content because the melted chocolate-Biscoff mixture will happily drench and coat most anything.

The bars are rich, dense, thick, and full of diverse texture. Soft and sweet marshmallows are the perfect squishy complement to the solidified melted chocolate. I like the striking visual contrast of the white and dark, too.

The chopped cookies add welcome crunch and serve to boost the overall cinnamon-ginger flavor profile. Although I’ll never say no to peanut butter and chocolate, pairing Biscoff twice with chocolate is a good call.

Make sure you have napkins handy, especially if you’re sharing them with a five year old. Or are just embracing your own inner five year old.

The best part of all is that they take less than five minutes to make.

Biscoff Marshmallow Chocolate Bars

By Averie Sunshine
These no-bake bars are virtually work-free and come together in less than 5 minutes. Sweet, fluffy marshmallows and chopped Biscoff Cookies (or graham crackers) are drenched in a bath of melted chocolate and Biscoff Spread (or Cookie Butter Spread). The bars are rich, dense, and taste far more decadent and indulgent than you’d imagine something that’s so easy to make.

Ingredients  

Instructions 

  • Line an 8-by-inch pan with aluminum foil, spray with cooking spray; set aside. In a large microwave-safe bowl, add 1 1/2 cups chocolate chips and heat on high power for 1 minute to soften and begin to melt. Add Biscoff spread and heat on high power for 30 seconds to melt, stirring to combine. Heat in 15-second bursts until the mixture can be stirred smooth, taking care not to overheat it.
  • Add the marshmallows, Biscoff cookies, and toss to coat evenly. Pour mixture into prepared pan, smoothing it lightly with a spatula. Sprinkle 1/4 cup chocolate chips evenly over the top. Place pan in the refrigerator for at least 2 hours to set-up, or until chilled and bars can be sliced. Bars will keep in an airtight container at room temperature for 1 week, in the refrigerator for up to 2 weeks, or in the freezer for up to 3 months. I prefer to keep them in the freezer (mine don't freeze solid) and serve them chilled.
  • Optional Variations: Add slivered almonds, macadamia nuts, or a handful of shredded coconut to the batter. Omit the Biscoff cookies or graham crackers and instead use Nilla wafers or chopped Oreos. Sprinkle white chocolate chips, cinnamon chips, peanut butter or butterscotch chips, toffee bits, diced peanut butter cups, or Rolos on top. Mix and match as desired.

  1. Since I know I won´t get any biscoff spread around here, I will go with your grandma´s version with peanut butter :) The recipe looks lovely, thank you for sharing!

  2. I can imagine making these with all chocolate, marshmallows and graham crackers for a super awesome s’mores bar with tons of texture!

  3. You had me at biscoff! Then you said it could be made in 5 minutes – so yeah, this is totally going to happen in my kitchen soon!

  4. oh gosh this looks so good…and I have 3 jars of biscoff that I can’t wait to use up…the photos look like a fudge we make for Chrismtas…now I can’t wait to try your recipe…yum!

  5. Our stores here FINALLY started selling Biscoff a few months ago, and I’ve already gone through multiple jars (ummm, mostly just with a spoon, though sometimes I attempt to be “good” and smear it on apples, haha). These bars look awesome, Averie, and I love your pictures – just fab!!

  6. Do you know that I have never had Biscoff or TJ Cookie Spread??! Where have I been? These bring back memories, Averie, because my grandma used to make these with colorful marshmallows as well. They were so good! These are a total Christmas snack treat, after opening presents, while awaiting the big dinner and the SERIOUS desserts! :-) At least, that is how it was around our house. These were the snacky, fun, in-between snacks…but OH SO GOOD! :-)

  7. I don’t think I’ve seen Speculoos or Biscoff or Cookie Butter here in Toronto, Canada yet! Either I’m not looking hard enough or I’m looking at the wrong shelf – you’d think it will be right by the Nutellas or Peanut Butters! That said, your Biscoff treats look so tasty! If you put this spread right in front of me now, I think I’ll try each and every one of them…then go for seconds! Is that wrong? Hehehe.

  8. I have always wondered what to do with Biscoff spread! It looks and tastes so yummy but other than putting on er bread? ya can’t even think of anything.. a cookie? hahaha had no idea. Love this!

    1. Well I have tons of recipes using Biscoff/cookiebutter, many of them linked in this post – because yes, I need to USE it other than just…use a spoon on it.

  9. Oh, these look so deliciously messy! Graham crackers and Biscoff sound like an irresistible duo! (Of course marshmallows and chocolate are welcome to any party.) :D

  10. I cannot get enough of this stuff! Especially in baking. These look like rice crispie treats on steroids. Definitely going on my to-bake list!

    1. I’m sue it does! Places like Target, Walmart, Marshall’s, TJ Maxx, random dollar store places, different grocery chains – I’ve seen Biscoff at all those places (some of them very random!)

  11. I’m not sure about these so you should definitely send me a large batch to test… oh who am I kidding, I’m in love with these.

  12. This sounds like another clean out your pantry cookie. Lol. I have never had cookie butter but the biscoff I’ve tasted with a spoon was just ok. But the Nutella now that’s a different story!

  13. I have to hurry and say that I think these look divine because I just saw the previous post that I missed and I’m drrroooolllliiiinnngg

  14. Bingo, that’s what I will make for that party we are invited! Thank you, Averie! :)
    Yes, I love Biscoff, we all do, it never stays in our home longer than two days. Those little once are so addictive!
    You know, I’ve been looking at this post and thinking: how did you manage to make such a perfect cut? :)

    1. Must have them WELL-CHILLED before the knife comes out and lots of practice botching many not-so-clean cuts :)

  15. Oh what a fabulous bar!!! I love marshmallow bars and it has been so long since I have made any. We have a work party on Friday, thinking I’ll whip up batch, after all you know I have Cokie Butter in the cupboard!!

  16. I am the same way – I love peanut butter, but have a soft spot for Biscoff. It gets me every time :)
    These bars look heavenly!

  17. Wow! These look heavenly! I just made your cinnamon sugar pretzels…and I added Biscoff. I love that stuff SO much!

  18. I love how flexible this recipe is. Sometimes there’s nothing better than a recipe that brings out the inner five year old in all of us.

  19. while at trader joe’s last week i grabbed the last 3 jars of cookie butter.
    and i did this with a huge sigh of relief.
    you know you’re a foodie when you breathe in a sigh of relief.
    did you also see the red pepper jelly was back? so happy!

  20. Your photos are so good! I do like Biscoff, but you can’t’ buy it here, so I have only had one jar before.

  21. I guess I can take my spoon out of my cookie butter jar and make these lovely bars. Thanks for the recipe!

  22. Love these. Love how neatly you cut them! When I first looked at the pics I actually thought you used a circular cereal grain, like Kix, they look so neat and tidy. And I love how they are a simple, straightforward, but delicious treat. Making these to share with friends tomorrow. Thanks, girl!

    1. Funny you should say they’re neat…they WERE neat when I cut them, nearly frozen. And in 3 mins in Caribbean air, they started melting. And oh boy. Nothing like some melting choc for food photos that’s not supposed to be melting!

      And if you make them, please report back!

  23. at times, i can’t even keep cookie butter in the house because I cannot be trusted around it. However, putting it into a recipe like this.. i think I can make an exception and hoard the TJs shelves. Who am I kidding? I already have a jar in the pantry and the only “recipe” i’ve used it for is spreading on crackers.

    All that chocolate and the marshmallows, this recipe is screaming “make me!” “make me!” as I sit here in the office wishing I was in the kitchen! the extra biscoff cookies inside – i would LOVE the texture those bring to the squares. wow, these look so good averie! Such a simple, quick yet creative little decadent dessert. :)

    1. I already have a jar in the pantry and the only “recipe” i’ve used it for is spreading on crackers. <-- you're a step ahead of me most times. Because I just use a spoon, no crackers :) And this is such an easy one, Sally. New spin on classic favorite! The pastel marshmallows circa 1986 have been updated! And it's a texture junkie's DREAM dessert. You would love love love it!

  24. I made something similar last year but that was waaaay before I discovered Biscoff. Now I want these!!!

    1. And I relinked to one I made in 2009 in the related recipe (eeek, the pics!) and yes, way before I discovered Biscoff, too!

  25. I’ve actually never had either Biscoff or the spread. These look like the perfect treat to take to a holiday party!

  26. Yum! I love biscoff – I had it in Belgium when I was a kid, but didn’t realize it was just melted gingerbread until a few years ago, haha.

  27. I think you out-did your grandma, but her green and pink marshmallows version sounds pretty cute. No wonder you turned into a peanut butter fiend.

    1. I bet you’ve had similar treats – I think they were a staple of every potluck type function for a couple decades – at least where I grew up!

  28. I’ve never tried any of those delicious spreads that people always talk about! I need to change that.

  29. My grandma used to make these with green and red marshmallows, too! Though, I must say that I like the sound of yours more! :)

  30. I’m hopping on a plane and coming over. Besides, I’m certain that these taste better when shared with friends :)

  31. If these aren’t the epitome of a gooey, perfect, ultra-decadence, I don’t know what is. They’re honestly mind-blowing how ridiculously indulgent and scrumptious they look, Averie!

  32. Oh my, these look yummy! I love how something that comes together so quickly can still be a decadent treat. I’m road tripping home for Christmas this weekend and had making granola bars for our car snacks in the back of my head. I might have to go sweeter with these instead. Memo to self: pack the wet wipes ;-)

    1. I was on your site last night and saw your orange bread. I was thinking how good that looked and granola bars sound great, too!

  33. Oh. My.GOD.

    My grandma used to make a boring version of these all the time! I think she went with the standard, Midwestern version using pb, chocolate chips, and graham crackers. She may even have mixed in butterscotch chips. This just reminds me of my grandma. Thanks for that.

  34. What is it with grandma’s and colored treats? Mine ALWAYS used red and green food coloring in cookies… whether or not it was Christmas haha. These look so easy (and good)!

  35. I haven’t ever used Biscoff! I need to try it though… these look absolutely decadent. Love how quick they are too – we need more recipes like this around this time of year!

    Made your cake batter funfetti blondies last night and we’ll be enjoying them today at school for our Christmas party! I may or may not have snuck a taste ;) DELICIOUS!

    1. I’m so happy to hear that you made the Funfetti Blondies! LMK how they were received & went over (and glad you already snuck a taste :) )

  36. Biscoff…addictive definitely describes it! I have to try and hide it in the back of my freezer so I don’t go crazy on it with a spoon. I was actually wondering if you would post a Biscoff recipe while you were in Aruba and here it is! Your no bake treats are so fun..lots of options for random bits of leftover chips and goodies. I love all that chocolate holding them together!

    1. And if you like Biscoff, you have to also try Nutella (per your comment yesterday) – totally different but may as well try all my fave spreads. And yes couldn’t be here without a Biscoff recipe…you know me well :)

  37. I’m all for putting biscoff in just about everything lately! Mostly into my belly straight from the jar. :P but I love this take on a childhood classic!

  38. I’m about to get to work on a biscoff project this morning. :) These bars sound heavenly! I’m a sucker for anything and everything involving marshmallows. I love that you put a modern spin on something your grandma used to make!

  39. I love these but have never tried them with Biscoff spread and cookies. While I love peanut butter, I have a soft spot for the cinnamon-gingersnap delicious-ness of Biscoff spread too. Definitely need to give this recipe a try!

  40. I always look forward to your trips to Aruba cause I know you’ll come up with something Biscoff-tacular!
    I’m certain your Grandma would approve of this version as well :) Take care there!

    1. It’s wouldn’t be a trip here without plenty of no-bake (bar) recipes, Biscoff, PB, and some Nutella!

  41. Love how simple, quick, and easy these are to make. Now, if only we could get our hands on biscoff in Canada! :)

    1. I’m sure you’ve checked on shipping from their site (I linked it in the post) but I can totally appreciate the frustration of not having it available in the grocery store!

  42. My grandma made those same bars, I’ve completely forgotten about them until you mentioned them! I love how you changed it up, yummy!

  43. Wow, every time I visit I’m reminded of how badly we need a trader joes here in Canada!

    I’ve never heard of biscoff… Sounds intriguing. Being allergic to peanuts, I never got to have those peanut butter + marshmallow squares, but I know exactly which ones you’re talking about!

    1. You’ve never heard of Biscoff? And you’re allergic to peanuts (how did I know not/remember this??) .. okay well Biscoff/Cookie Butter is the answer to your prayers! I’m sure you’ve had sunflower seed butter, Nutella, and all kinds of gourmet nut butters or spreads & now you HAVE to try Biscoff or similar.

      And per your comment reply re stuffing post-Thanksgiving. You know maybe some people serve it with Xmas dinners and such, but not where I grew up. I really peaks as a Thanksgiving food. But then again maybe others do eat it for Xmas.

      1. Okay, so I had to google Biscoff. It’s ground up cookie? What the… I need to make this. Not sure they have gluten-free kinds out there, so I’ll just make it myself. Wow.

        So interesting about stuffing! You’re not the only one that’s told me that stuffing is a Thanksgiving thing more than Christmas. Now I know!

      2. Pulverized gingersnap/gingerbread cookies. But there’s plenty of ginger, molasses, cinnamon and a robust kick. I also am unsure about the oil b/c it’s not a greasy spread but a bit more dry. Not dry, but not like a ‘natural PB’ and definitely not drippy like almond butter. It’s a little project of mine coming up to recreate :) I’ve seen other recipes online for it and for various reasons, none really have caught my eye so I need to get to work and figure it out on my own.

        Good to know Im not the only person who said that about stuffing, too. I thought I was just missing something!? :)

  44. Like Erica, I have never tried biscoff spread. I’ve seen it at the store and been tempted to buy it, but haven’t yet. Maybe it’s time…

  45. I still have not tried biscoff! I think im afraid ill consume the jar in one sitting! Delicious treat. Love the chocolate addition
