Biscoff Toffee Crunch Bars are thick chewy bars filled with the deliciousness of Biscoff butter, chocolate chunks, and crunchy toffee bits. Topped with Biscoff icing these bars are irresistible!
Why you'll love this recipe
- This is a chewy, dense bar full of Biscoff spice flavor and toffee crunch.
- These bars have Biscoff icing (that dries beautifully for mailing) sprinkled with toffee bits.
- The bars maintain their freshness for at least a week
If you or someone you love is a Biscoff fan, I highly recommend that you bake a pan of Biscoff Toffee Crunch Bars. Drizzle on the icing or spread it over the whole top (it’s that good).
If nut allergies keep you from using packaged toffee (Heath baking bits) which contains almonds, home made toffee bits are very easy to make. Try my recipe for nut-free toffee bits.
Instructions
This is an overview of the instructions. The full instructions are in the recipe card below.
- Whisk together the flour, baking powder cinnamon and salt.
- In the bowl of an electric mixer, cream together the Biscoff cookie butter, butter, and brown sugar until combined. Add the eggs and vanilla. Beat until fluffy. Mix in the flour mixture until combined.
- Stir in the toffee bits and chocolate chips.
- Use a spatula to evenly spread the batter into the prepared pan.
- Bake for 25-30 minutes or until the top is golden and a toothpick inserted into the middle of the cake comes out clean.
Storage
Store bars at room temperature in between layers of wax paper in an air tight container or wrapped in plastic wrap inside an air tight container for up to one week.

Biscoff Toffee Crunch Bars with Biscoff Icing
Ingredients
Batter
- 2 ¼ cups all-purpose flour
- 2 teaspoons baking powder
- 2 teaspoons cinnamon
- ½ teaspoon salt
- ½ cup Biscoff cookie butter smooth or crunchy
- ¼ cup unsalted butter room temperature
- 1 ½ cups dark brown sugar packed
- 3 large eggs
- 2 teaspoons vanilla extract
- 1 cup toffee bits
- 1 cup chocolate chips I used a combination of dark and semi-sweet
Icing
- ¼ cup Biscoff cookie butter
- 2 cups confectioners sugar
- ¼ cup + 1 tablespoon milk
- 1 teaspoon vanilla extract
- ⅓ cup toffee bits
Instructions
Bars
- Preheat oven to 350 degrees F. Using non-stick spray, lightly grease a 9” x 13” baking pan. Line the pan with parchment paper with a 2” overhang on long sides of the pan. Lightly spray over the parchment as well.
- In a medium bowl, whisk together the flour, baking powder cinnamon and salt.
- In the bowl of an electric mixer, cream together the Biscoff cookie butter, butter, and brown sugar until combined. Add the eggs and vanilla. Beat until fluffy (about 3 minutes).
- Mix in the flour mixture until combined.
- Stir in the toffee bits and chocolate chips.
- Use a spatula to evenly spread the batter into the prepared pan.
- Bake for 25-30 minutes or until the top is golden and a toothpick inserted into the middle of the cake comes out clean.
- Cool in pan for about 20 minutes then run a knife along the edges touching the pan and use the parchment overhangs to lift the bars out of the pan onto a wire rack. Cool completely before icing.
Icing
- In the bowl of an electric mixer combine Biscoff cookie butter, confectioners sugar, ¼ cup milk, and vanilla. Beat until smooth. Add additional milk to thin the icing if it is too thick.
- When ready to ice, remove from refrigerator, remove the parchment and place on top of wax paper on a counter or cutting board.
- Drizzle or spread icing then immediately sprinkle with toffee bits.
- Allow icing to set for at least 1 hour, then move onto cutting board and slice.
- Allow icing to harden completely before storing. Store bars at room temperature in between layers of wax paper in an air tight container or wrapped in plastic wrap inside an air tight container for up to one week.

Mama's Gotta Bake
These look amazing. I was wondering what to bake tomorrow, and I think I have my answer!
themondaybox
Thank you ,Sheryl! I hope you will try them and let me know what you think. I am glad you stopped by. 🙂
Reeni
Those look incredible! Your description has my mouth watering! I haven't used biscoff in my baking yet but it's been on my radar for a while. Things like this keep me up at night too - sometimes I even dream of recipes.
themondaybox
Thanks,Reeni! These bars make me very happy. Biscoff seems to work just like a nut butter in recipes. It takes the place of some (or maybe all?) of the butter (or other fat) in the recipe. The flavor is heavenly. 🙂
giverecipe
These look so chewy and scrumptious! So dangerous to see these at this time of night! The only psychiatric help for foodies like us would be baking or cooking no matter what the time is!
themondaybox
Thanks, Zerrin! I agree. Cooking and baking are therapeutic! I am so glad I found your site. I am looking forward to learning about Turkish food!
mmmarzipan
These look dangerously good!!!
themondaybox
Thanks. I definitely found them to be dangerous 🙂 Bake with caution. 🙂
Ashley
I do love cookie butter! Occasionally I swirl just a little bit into my oatmeal... haha I just bought a jar of the new crunchy kind Trader Joes started selling too - can't help myself. These sound awesome! And I love that you woke up in the middle of the night with ideas for baking : )
plasterers bristol
Wow these are addicting, tried these on the weekend....
themondaybox
I'm so glad you enjoyed them, Simon! I found them addicting too. 🙂
BruCrew Life
I wouldn't be able to mail those bars...I'm thinking hiding in a closet munching away sounds like a better idea!!! These look incredible!! I am slightly addicted to the BIscoff spread!!! And waking up in the middle of the night with a baking idea is completely normal 🙂
themondaybox
Thanks, Jocelyn! I will confess to keeping a secret stash of a few bars before I mailed these off. 🙂 They were for research purposes, of course. I can only bring the Biscoff spread into the house if I am going to use it to bake very soon. Otherwise, I eat the whole jar with a spoon! Glad to hear that my middle of the night baking epiphanies are "completely normal". 🙂

Oh goodness. These bars look amazing! And I love that you used Biscoff. Yum.
themondaybox
Thanks, Emily! I love Biscoff/cookie butter and wanted to make sure these bars were full of Biscoff flavor!
The Café Sucré Farine
Oh wow, these have my name written all over them. Two of my favorite things are Biscoff and toffee bits and you put them together, yum, yum yum!!
themondaybox
I hope you will try them, Chris ,and tell me what you think. I am very excited about how the taste and texture turned out. 🙂 Biscoff and toffee just seem made for one another.
Monica
I might be one of the very few who hasn't even tried cookie butter/Biscoff. Your bars look great - I like the sound of all that texture going on in them.
themondaybox
I hope you will try them, Monica, and end your lack of Biscoff experience. 🙂 The funny thing is, most of the comments come from people who haven't tried cookie butter/Biscoff yet. I hope to remedy this problem. 🙂 The chewiness of these bars is great!
bakerbynature
Ooooooh these look addicting!
themondaybox
Thanks, Ashley! If you love cookie butter/Biscoff you will love these. I was addicted at first bite. 🙂
Mrs. DeYarmond

themondaybox
Sarah, you are so sweet! Thank you. Your photos always look like they come out of an amazing French cookbook. I do know that we both love the flavor of Biscoff because your biscoff cake in a mug is delicious!
Mrs. DeYarmond
You're such a doll thank you so much for all your sweet compliments !! Oh yeah absolutely I love Biscoff ! Btw have you tried the mugcake ? Let me know dear 🙂
themondaybox
I have gathered the ingredients and plan on making it on Wednesday. My son is coming home from college (spring break)on a late train and I thought the mug cake would be perfect then. I will let you know!
Suzie
I haven't had Biscoff either. I don't know if I could find it here. I live in the country and well, they don't have a lot of stuff I go looking for...lol! These do look amazing and sound amazing! I love that you came up with the recipe yourself. I have the same illness as you, thinking of recipes or things to cook while in bed. Being on my phone on Pinterest before sleep doesn't help...ha!
themondaybox
Thank you, Suzie. 🙂 I am definitely spoiled with access to cookie butter at Trader Joes and our supermarkets practically at my doorstep. Maybe its not spoiled though. Maybe its just feeding my Biscoff habit. 🙂 Seriously, let me know if I can ever help by mailing you an "exotic" cooking supply. I would be happy to.
Suzie
Thank you, that is so sweet of you!
Jess @ On Sugar Mountain
Okay so I feel terrible admitting this but I've never had Biscoff? I know I know! But now I have a reason to try it! These bars look absolutely scrumptious Wendy 😀 Enjoy your weekend!
themondaybox
Jess, my friend, this is a warning. You may not want to try Biscoff. It is HIGHLY addictive. You will put it in baked goods. You will eat it with a spoon. You will dream about it. It is the dictionary definition of OMG good. Just a thought. 🙂 Have a great spring break!
