Biscoff Blondies are chewy, buttery blondies filled with creamy biscoff butter and crunchy biscoff cookies. They are such a fun way to enjoy lotus biscoff cookies and biscoff butter!
I feel like Lotus Biscoff Butter and Biscoff Cookies are having a real moment right now. Either that or I'm just way late to the game. Whichever one it is, I am on the train and not stopping anytime soon! These Biscoff Blondies use both the butter and the cookies to give you a real one-two punch on Biscoff flavor! If you love the double up on flavor in one cookie you should try my No-Bake Cookies with Peanut Butter Glaze!

Ingredient Notes
- Measuring the all-purpose flour correctly is very important. I suggest weighing your flour out. If you want to use a measuring cup, make sure you spoon the flour into the cup and level it off with a knife. Don’t use the cup to scoop directly from the flour.
- If you can’t find Biscoff cookie butter at your local store you can buy it here or use another type of cookie butter.
- Biscoff Cookies will add some crunch and flavor to the blondies, but you can leave them out if you can't find them in your local store. If you love that crunch you'll also love my Strawberry Crunch Cookies.
See the recipe card below for a full list of ingredients and measurements.
Substitutions and Variations
- The Biscoff spread and cookies can be substituted for any speculoos butter or cookie if you can't find the specific brand.
- Chocolate chips can be added to the batter to add flavor. Biscoff white chocolate blondies would be delicious! I also use white chocolate in these White Chocolate and Raspberry Blondies.
- You can add cocoa powder to the blondie batter to make these into biscoff brownies! This Fudgy Brownie recipe is one of my favorite desserts to make.
- You can use brown butter instead of regular butter for a richer taste. I also use brown butter in my Brown Butter Blondies.

Step-By-Step Instructions
STEP 1: Preheat oven to 350 degrees (F). Line an 8×8 baking pan with parchment paper.
STEP 2: In a small bowl combine the flour and salt. Whisk to remove lumps.
STEP 3: In a medium bowl combine the butter, brown sugar, granulated sugar, and Biscoff butter. Mix until fully combined and smooth. Add the eggs and vanilla and combine.
STEP 4: Fold in the flour mixture until just combined.
STEP 5: Fold in crushed Biscoff cookies.
STEP 8: Press the Biscoff blondie batter into the prepared pan. Bake for 30-35 minutes. The top should start to crack. If you would like the blondies to be more firm you can bake them for 5-10 minutes longer.
Expert Tips
- Press extra biscoff cookies into the top of the blondie batter before baking. This will add more texture, make the blondies more visually appealing, and add flavor.
- Use an oven thermometer. Most ovens run either hot or cold. Using an oven thermometer ensures that you are baking your blondies at the perfect temperature.
- Don’t use cold ingredients. Ensure that all of your cold ingredients are at room temperature before making your blondie batter. The ingredients will combine much easier.
- Weigh your ingredients. One of the most common baking mistakes that I see is measuring incorrectly, especially with flour. The best way to get accurate measurements every time is to weigh them with a kitchen scale.
- Don’t overmix. You need to mix your batter until all of the ingredients are JUST combined, otherwise, you will make too much gluten and your blondies will be tough and dry instead of chewy.
Recipe FAQ's
Brownies use cocoa powder and/or chocolate to get their flavor. Blondies use vanilla and brown sugar.
You can get it on Amazon. If you don't want to order it you can find other cookie butters at most grocery stores.
You can fully remove the cookies without affecting the blondies. You can add up to ½ of a cup of extra cookies. Adding more biscoff butter will affect the texture, so remove equal parts of the unsalted butter if you do this. If you remove any biscoff butter add equal part of unsalted butter.
Yes! They should have a soft, slightly gooey center and a firm edge. If you don't like the gooey center you can bake them for a bit longer.
Room Temperature: Blondies are best eaten in the first two days, but they should be good for up to 5 days at room temperature if stored in an air tight container.
Refrigerator: If stored correctly in an airtight container these blondies will last up to 1 week in the fridge.
Freezer: If stored correctly in an airtight container they will last up to 2 months in the freezer.

Boy, were these delicious! We adore cookie butter at my house and they were a big hit. I made a caramel cookie butter drizzle for the top. It wasn't necessary, but it was for a baking contest at work so I wanted a little extra something. I won. 😁
Ellie Haley says
This made me so happy! The caramel cookie butter drizzle sounds genius!
Ty says
Aren't these cookie bars, not blondies? Blondies are usually made with only brown sugar, no granulated sugar.
Ellie Haley says
Definitely blondies! The big differentiator is the use of vanilla instead of cocoa powder. But you can replace the white sugar with all brown sugar if you prefer!
Alvy says
tasted good, but mine came out underbaked. I followed the recipe, and took it out as instructed. I ended up having to cut the edges and threw away the center because it was gooey. Also, the instructions does not say when to add eggs or vanilla. I added it anyway with the wet ingredients.
