Biscoff Layer Bars much like fudge, these rich bars are made with cookie butter and has a layer of crunchy cookies!
I’m supposed to be starting a healthy eating and exercise series, but instead I’m posting these decadent Biscoff Layer Bars. I’m just going to blame it on Julie at White Lights on Wednesday! She posted these Peanut Butter Oreo Magic Bars and the second I saw them I wanted one…or two!
I meant to make them exactly as her recipe and send them to one of the boys teachers. But, when I got to the grocery store they were out of my brand of peanut butter. I’m brand loyal on certain items. Now, I’ve been avoiding the whole Biscoff phenomenon simply because I knew I’d eat it straight from the jar, that’s how you eat peanut butter, right?!
I caved.
I bought the Biscoff.
It’s sinful.
In order to not eat it straight from the jar and because I wanted to try this recipe, two worlds collided and much like a magician I did a houdini wave of the hand and switched out the peanut butter for the Biscoff and life has been fabulous ever since…getting in my skinny jeans, not so much!

Okay, never mind! I found the comments once I posted mine I saw a link that said Older comments, clicked on that and voila! There they were! 🙂
Holly says
These look A.M.A.Z.I.N.G! I’m trying to read the comments, but I can’t find them. Even when I click on the 33 comments at the top, it doesn’t bring them up. Before I make a new recipe, I like to read the comments so that I can see any insider tips! I keep trying this link https://www.callmepmc.com/biscoff-layer-bars/#comments
Any advice?
Kristyne says
Making these tomorrow!
Instead of peanut butter chips I’m using white chocolate chips and using golden oreos over original and subbing out the nuts.
I wonder if I do a layer of mini marshmallows instead of the nuts?! Is that too much?! lol
I’ll let you know how they turn out 😉
Paula says
I think the marshmallows would be fab and not too much at all, go for it! Let me know how they are!
Hilary says
I don’t like peanuts or peanut butter at all – what would you think of a swap with crumbled Biscoff cookies for the peanuts and butterscotch or white chocolate chips? Is the crunch important?
Paula says
oh def, you could sub any nut or if you don’t like nuts at all any crunchy cookie would work, M&Ms, white choc would be fantastic!
Krista @ joyfulhealthyeats says

pat lambert says
I don’t want to sound “dumb”, but what heck is Biscoff.
Paula says
Not dumb at all… it’s a spreadable ‘butter’ made out of cookies. It’s the consistancy of peanut butter so I’m assuming they grind it and mix with some type oil, but has a sweet taste. It’s VERY good.
Brenda says
This sounds wonderful…I just tried Biscoff for the first time and ….Oh, My!….it’s awesome…I was visiting in NC, came home to Florida and can’t find it here…..Yet!…..but I will find it…lol
When I saw that you mixed Biscoff with sweetened condensed milk…I though…hmmmmm, wonder what else that mixture would be good on…..hmmmmm…….any suggestions?…..anyone?
Brenda
Paula says
I think it would be could mixed in ice cream!
Brenda says
Hmmm, warmed and drizzled on ice cream….sound great
tanya says
Wow Paula, these looks too tempting! Yes, Biscoff is a dangerous thing. Once you have it, you can’t stop eating it….from the jar!
Paula says
