🍪 What is Biscoff?

Lotus Biscoff cookies are crunchy cookies with caramel-like flavor. They contain warm spices like cinnamon and are made with brown sugar for deeper flavors. Biscoff spread is made of crushed biscoff (speculoos) cookies and has the consistency and texture of peanut butter, but tastes like biscoff cookies. It's delicious, with cozy and warm notes of caramel, and it goes perfectly in this Lotus Cookie Butter Blondies recipe.

♥ Why You'll Love This Recipe

Gooey & Chewy - These Cookie Butter Blondies are filled with pools of melted chocolate and Biscoff butter and they have a fudgy-like texture similar to a brownie!

Not Overly Sweet - Only using brown sugar and no granulated sugar gives a chewy texture and deeper notes of caramel, like my Brown Butter Chocolate Chip Blondies.

Quick & Easy - Aside from the brown butter, this entire recipe is made in one bowl, and bakes up in less than 25 minutes! Try my Salted Caramel Blondies for another easy blondie recipe.

No leavenings - Like most of my blondie recipes, this recipe uses no baking powder or baking soda, and because of that, we achieve more chewy goodness without the cake-like blondies you'll find in other recipes

Biscoff Cookie Butter - These Blondies are elevated with the addition of cookie butter! It gives an even deeper and rich nutty flavor, like my Biscoff Stuffed Cookies and Biscoff Tiramisu.

📝 Ingredient Notes

A full list of ingredients, quantities, and instructions are located in the recipe card at the end of the post.

Butter: For this recipe, I use brown butter, which is melting the butter, than continuing to cook it to brown. This gives the blondies a rich and nutty flavor.

Brown sugar: This recipe uses all brown sugar, which cuts down on the sweetness a little, but it also gives the blondies more of a chew.

Eggs: I use one whole egg and one egg yolk.

Biscoff spread: Cookie butter can be found in just about any grocery store. You can buy the Biscoff brand, or just any cookie butter brand. Trader Joe's has a really good one.

Salt: balances out the sweetness and adds more flavor.

Flour: All purpose flour works best with this recipe.

Chocolate: I use 70% dark Lindt chopped chocolate for this recipe. It's pretty interchangeable with semi-sweet chocolate. Feel free to use any brand, even chocolate chips.

Lotus Biscoff Cookies: Topping the blondies with biscoff cookies right before baking gives them such a delicious crunch, with added biscoff flavor.

🍴Special Equipment

Kitchen Scale: It's so important to use a kitchen scale for accurate results.

Baking Pan: My favorite 8 inch Square USA pan is from USA pan. It has straight edges, bakes evenly, and never fails. I highly recommend purchasing a good quality baking pan for your bakes.

Mixing bowls: I love using glass Mixing Bowls when making batters and doughs.

⇄ Substitutions

Biscoff: You can leave off the Biscoff cookies before baking if you want. You can also add drizzled Biscoff to the Lotus Blondies when they're done baking.

Chocolate: You can switch up the chocolate and use all chopped chocolate or all chocolate chips. You can even use a mixture of chocolate like milk and dark. Try not to make it 100% dark chocolate, though, because that will cut down a lot on the sweetness.

✨ Variations

These Biscoff Blondies are delicious as is, but if you'd like to jazz them up some more, you can add any kind of mix ins like nuts or chocolate candies. Experiment and see what you like!

𓎩 Step-by-Step Instructions

Step 1

Melt butter in a medium sauce pan on medium heat. Stir the butter to make sure it melts evenly. Once the butter is completely melted, it will start to foam up. Continue stirring the butter.

Step 2

As it cooks, it will start to change into a deeper color. This could take 6-8 minutes.You'll start to notice a nutty aroma and the butter will begin to have brown specs at the bottom of the pan. The entire process of browning butter from start to finish should not take more than 10 minutes on medium heat.

🎩Trick: Using a spatula instead of a hand mixer reduces the chances of over mixing, but once your ingredients come together, stop mixing.

Step 3

In a medium bowl, add the slightly cooled brown butter and brown sugar and mix until combined.

Step 4

Add egg and egg yolk and mix.

Step 5

Then add the Biscoff spread and mix.

Step 6

Add the salt and flour and mix until incorporated.

Step 7

Lastly, add the chocolate and mix until completely combined.

💡 Hint: Use a light colored metal baking pan. This will allow the blondies to bake evenly.

Step 8

Pour the batter into the prepared baking pan and add chopped chocolate and Biscoff cookies (optional) and bake for 20-25 minutes. You'll see the sides get a little light brown and the middle will have puffed up some. A toothpick inserted in the center should come out clean. Don't over bake.

💬 FAQ

What does Brown Butter do to the Blondies?

Brown butter instead of regular or melted butter creates a deep and nutty flavor that gives off notes of caramel.

How can I get a gooey blondie?

To achieve a gooey blondie, this recipe uses an extra egg yolk, brown butter, chocolate chunks, and no leavening agents (to avoid cakey texture).

💡Pro Tips

Measure Flour Correctly - As always, with any recipe, use a kitchen scale, as it is the best form of measuring your ingredients. If you don't have a kitchen scale, fluff your flour, scoop flour with a spoon into a measuring cup and level off.

Parchment paper - To avoid sticking, make sure to line the pan with parchment paper.

Don't burn the brown butter - Once the brown butter starts to pop, foam, and form specs at the bottom of the pan, remove it. Otherwise you could burn it and it will end up tasting bitter.

Don't over mix - Using a spatula instead of a hand mixer reduces the chances of overmixing, but once your ingredients come together, stop mixing.

Don't over bake -Start checking the blondies at 20 minutes to ensure you don't over bake. You want to make sure you end up with chewy and gooey centers!

Light-colored pan - Use a light colored metal baking pan. They help cook evenly and doesn't cook too fast.

High quality chocolate - I like using Ghirardelli, Lindt, or Guittard because I know they all taste wonderful in recipes. Here's more info on baking with the right chocolate.

❄ Storage

Once baked up, they will do quite well at room temperature. Store them in an airtight container for 4-5 days.
