Biscoff Marshmallow Chocolate Bars

My grandma used to make bars like these but she used pink and green marshmallows.

And she used peanut butter, but I went with Biscoff, twice.

 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.

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 (No-Bake)

Prep Time: 5 minutes

Total Time: 5 minutes

Yield: One 8-by-8 inch pan, 9 very generous squares

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.


1 1/2 cups semi-sweet chocolate chips, for melting

1/3 cup Creamy Biscoff Spread or Cookie Butter Spread (peanut butter may be substituted although the flavor will not be the same)

3 to 3 1/2 cups mini-marshmallows

1 cup Biscoff Cookies (10 to 12 cookies) or Bistro Biscuits, roughly chopped (substitute with about 2 full-size sheets chopped (cinnamon) graham crackers)

1/4 cup semi-sweet chocolate chips, for sprinkling (white chocolate, butterscotch, peanut butter, or cinnamon chips may be substituted)


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.

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

      And now you have the new TJs in your area, you have to try the Cookie Butter!

    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…

  3. Leanne @ healthful pursuit — December 19, 2012 at 3:26 am (#

    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!

    • Averie @ Averie Cooks — December 19, 2012 at 7:25 am (#

      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.

    • Leanne @ Healthful Pursuit — December 19, 2012 at 10:59 am (#

      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!

    • Averie @ Averie Cooks — December 19, 2012 at 11:06 am (#

      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!? :)

    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!

    • Averie @ Averie Cooks — December 19, 2012 at 7:18 am (#

      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 :)

    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!

    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.

    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 ;-)

    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!
