Amazing one bowl Biscoff Brownies made from scratch. Thick and fudgy chocolate brownies made with real chocolate and stuffed with big chunks of Biscoff cookie butter.
Hello Biscoff Brownies! 👋🏻
Introducing my new fave brownie. Made with real chocolate, these one bowl (no mixer) brownies are deliciously sweet and oh-so-fudgy. The best part? They’re stuffed with big dollops of Biscoff cookie spread.
If you love cookie butter, these Biscoff Brownies are for you!
I love a good brownie. And since Biscoff cookie spread landed on our supermarket shelves I’ve been obsessed. So it was only a matter of time until the two collided to make one EPIC sweet treat.
These Biscoff Brownies are heavenly. They’re made with a real chocolate brownie batter, that has cocoa powder AND chocolate chips in it, for a triple choc dessert. But the star of the show is the mountain of Biscoff cookie spread that’s studded throughout the brownie bars.
Once baked, you’ll have gooey pockets of Biscoff stuffed throughout your brownie. So expect a mouthful of rich, chocolate brownie that suddenly tastes like a buttery cookie. Ah-mazing.
And after you make and eat these, put the rest of your Biscoff jar to good use and make my Biscoff Cheesecake. You. Are. Welcome.
How to make Biscoff Brownies
- This is a simple one bowl brownie recipe. You don’t need an electric mixer.
- Start by melting together your butter and dark chocolate. I recommend using a block of good quality chocolate that’s a least 45-70% cocoa. Avoid chocolate melts or chocolate chips if you can.
- Add your sugars. We use both caster sugar and brown sugar in this recipe. If you don’t have caster sugar, you can swap it 1:1 with granulated sugar. Read more about caster sugar here.
- Next, we add a dash of vanilla extract. Then mix in 3 large eggs, one at a time. By now, your brownie batter will be very thick and chocolate-y.
- Finally, add your plain flour, cocoa powder and salt. Then, throw in your chocolate chips (optional but totally worth it).
- Transfer your brownie batter to an 8 inch baking tin lined with baking or parchment paper.
- Then comes the fun part! Dollop BIG spoonfuls of cookie butter all over the top of your brownie batter. Use a knife to gently swirl the cookie butter into the brownie but don’t mix it too much as you don’t want the two to combine.
- Bake your brownie until it no longer wobbles in the middle and then leave to cool completely before cutting to serve.
- To get a super fudgy brownie, place your brownies in the fridge for a couple of hours to firm up. If you prefer a warm brownie, heat your brownies in the microwave for 30 seconds or so before serving. Add a dollop of whipped cream or a scoop of ice cream for the ultimate brownie treat.
What chocolate should I use for brownies?
Use a good quality chocolate that you would be happy to eat (avoid the cheap stuff if you can). I use a block of dark chocolate instead of chocolate melts or chocolate chips.
Go for chocolate that’s at least 45% to 70% cocoa for best results. You don’t need your chocolate to be too sweet, as you’ll get plenty of sweetness from the sugar, cookie spread and chocolate chips.
BAKING Tip
If you love fudgy brownies, place your brownies in the fridge for a few hours after they have baked. They’ll go extra fudgy in the middle!
How do I store my brownies?
Store your brownies in an airtight container in the fridge. Brownies typically firm up in the fridge and go extra fudgy (which I love!). If you prefer a warm brownie, simply microwave your brownie for 20 seconds or so before serving.

Let’s Bake
Biscoff Brownies
Biscoff Brownies with big swirls of cookie butter swirled into the batter.
Ingredients
- 115 grams (1/2 cup or 1 stick) unsalted butter
- 200 grams (1 and 1/3 cup) dark chocolate, broken into pieces
- 100 grams (1/2 cup) caster sugar or granulated sugar
- 90 grams (1/2 cup) brown sugar
- 1 teaspoon vanilla extract
- 3 large eggs, cold
- 70 grams (1/2 cup) plain flour or all purpose flour
- 20 grams (1/4 cup) cocoa powder, sifted
- Pinch of salt
- 75 grams (1/2 cup) chocolate chips
- 180 grams (3/4 cup) Biscoff cookie butter
Instructions
- Preheat oven to 180 C (350 F) standard / 160 C (320 F) fan-forced. Grease and line an 8-inch square pan with baking or parchment paper, ensuring two sides of the paper overhang.
- Add butter and chocolate to a heatproof bowl and microwave until melted, stirring every 30 seconds. Leave to cool slightly.
- Next, add sugars and vanilla to the melted chocolate mixture and stir. Add eggs, one at a time and stir until combined.
- Add flour, cocoa and salt, and gently fold until the brownie batter is thick and smooth. Finally, add chocolate chips and gently stir.
- Pour mixture into prepared baking tin and very gently smooth over the top. Dollop spoonfuls of cookie butter all over the top of the brownie.
- Gently swirl the cookie butter into the brownie batter using a butter knife. Try not to over mix as you still want to keep big chunks of cookie butter throughout the brownie.
- Bake for approximately 30-35 minutes or until cooked through. It should start to crack on the edges and no longer wobble in the middle. Leave to cool completely before cutting into squares to serve. Store brownies in the fridge.
Notes
Chocolate: I recommend using a good quality chocolate that’s between 45-70% cocoa.
Storage: For a truly fudgy brownie, store them in the fridge.
Sohaila says
Hi can I melt the biscoff butter littel bit before spread it on the top so it will be easy
Jessica Holmes says
Yes you can!
Mahfuzah says
Hello!!if I want to bake in 10″ pan,do I double the recipe?😊
Jessica Holmes says
Hi, I haven’t tried doubling the recipe so I can’t recommend I’m sorry. For a larger brownie, you could try my Big Batch Brownie recipe.
Fuzah says
Do I double the recipe if I want to bake it in 10″ pan?
Btw your biscoff brownies awesome!!! I can just remove the biscoff spread to bake normal brownies!!fudgy and nice!
Jessica Holmes says
So glad you like them!! I haven’t tried doubling the recipe so I can’t recommend I’m sorry.
Malieta says
Hi Jessica,
I absolutely love your recipes and have tried this one before and it was a bit crumbly. I think it was because I didn’t allow the melted chocolate to sit long enough.
I was just wondering if I could make the Biscoff brownies with a cup of caster sugar instead. We had a raw and brown sugar recall in NZ and it is difficult to get brown sugar at the moment.
I look forward to your reply.
Jessica Holmes says
Hi Malieta, yes absolutely, that’ll be fine!
Jaz says
Hi I am planning on making these tomorrow and was wondering if the actual biscoff cookies could be cooked on top of the brownies -would this work or would the cookies just burn?
Jessica Holmes says
Hi Jaz, yes you can! I do it for my Biscoff Blondies!
Kat says
These brownies are delicious! Super easy recipe to follow and turns out amazing. Definitely a new favourite!!
★★★★★
Jessica Holmes says
Yay! Love hearing that Kat!
Lani says
These were super chocolate-y but really, really dry. I would probably forego the 1/4 cup of cocoa.
★★★
Jessica Holmes says
Hi Lani, with such a high ratio of butter and chocolate to dry ingredients, these brownies really shouldn’t be dry. If they were, you may have added flour/cocoa (make sure you measure using a baking scale) or over baked them.
Eloise says
Delicious! I’ve made 2 batches already. I found slightly heating the biscoff spread in the microwave for 20seconds makes it easy to pour over the brownie mix in the pan. Also tried a batch without the dark chocolate and found it to be more cake like and less fudgy which I really liked.
★★★★★
Jessica Holmes says
Amazing! Love hearing that Eloise!
Dakshee says
Hey is it necessary that the eggs need to be refrigerator-cold? Also – since we’re adding cold eggs, do we make sure that the melted chocolate has completely cooled down too? Or is it okay if it’s slightlyy warm when we add the eggs?
Jessica Holmes says
Hi Dakshee, you can use room temperature eggs if you prefer. And the melted chocolate shouldn’t be very warm if you stop to stir it every 30 seconds, so it should be fine.
Purva says
Hi Jess, can we swap the chocolate chips with some Lotus biscuit pieces?
Jessica Holmes says
Yes! Yum!
Sharon says
Hi
How long do these keep for in the fridge?
Can they be frozen? If yes, how long would you recommend? One month?
Thank you.
Jessica Holmes says
Hi Sharon, these do keep well in the fridge and they freeze well too. They don’t usually last that long in my house so I’m not too sure on exact time frames.
Nasrin says
Hi, would it be possible to reduce the sugar content of this recipe? If yes, how much can I reduce?
Jessica Holmes says
Hi Nasrin, I haven’t tested the recipe with less sugar. I don’t recommend reducing it by much as sugar can add moisture and structure to baked goods as well as sweetness.
Sheba says
So delicious! My first time using biscoff!

Werner says
Hi there, I love your recipes, they always work out well. Thanks for your hard work!
What is this Biscoff cooky butter you put on top? What can I replace it with?
Thanks and have a fantastic week.
Werner
Jessica Holmes says
Thanks Werner! If you don’t have access to cookie butter, you could use peanut butter, Nutella or another favourite spread?
