Why This Recipe Works

  • Cookie butter frosting brings delicious Biscoff flavor. I know you’re wondering why there isn’t any Biscoff butter in the cookie base. Hear me out: The brown sugar cookie actually pairs perfectly with the frosting because you have two flavors that complement each other. A cookie packed with Biscoff and a frosting packed with Biscoff just all blend together. With the frosting, you get that yummy Biscoff spread that can sing on top of the brown sugar cookie base!
  • Soft and sweet. These cookie butter cookies are soft and sweet thanks to a few important ingredients! The molasses and the cornstarch. These two ingredients help to bring a delicious sweet flavor (thank you molasses) and a soft and thick texture (thank you cornstarch)! 

Ingredient Notes

Cookie Butter Cookie ingredients portioned into glass bowls on a silver baking sheet.
  • Unsalted Butter: If using salted butter instead of unsalted, reduce the amount of salt 1/4 of a teaspoon per 1/2 cup of butter in the recipe. 
  • Light Brown Sugar: This is a brown sugar cookie base, so of course we need brown sugar! I used light brown sugar because I wanted a more mellow flavor to not super compete with the Biscoff buttercream (since we’re also adding some molasses). Dark brown sugar has extra molasses in it, so the dark + added molasses would be much more molasses. 
  • Molasses: Adding molasses to cookies aids in making a cookie soft and chewy, all while adding a bit of color and sweetness!
  • Cornstarch: The cornstarch helps make the cookies thick and chewy, while making sure they are moist! 
  • Cookie Butter Frosting: You’ll need to make 1 batch of my Biscoff Buttercream for this recipe. For that, you’ll need butter, Biscoff butter (also known as Biscoff spread, Speculoos cookie butter or lotus Biscoff cookie butter), powdered sugar, salt and heavy cream. 

Step-by-Step Instructions

  1. Cream the wet ingredients. Beat the butter and brown sugar in the bowl of a stand mixer fitted with the paddle attachment for 2 minutes or until smooth and light. Add the eggs and vanilla extract and mix until combined, scraping down the sides of the bowl as needed. 
  2. Add the dry ingredients. Add the all purpose flour, cornstarch, baking powder, baking soda, and salt. Mix until the dough just comes together. Do not over mix.

  1. Portion into dough balls. Using a 1/4 cup, portion into dough balls. Place 6 on a baking sheet lined with parchment paper. Using the palm of your hands, gently press down on each ball to form a thick disk.
  2. Bake. Bake the cookies at 350°F for 11-13 minutes or until the edges are set and the centers are no longer shiny. Do not over bake. Remove and let cool for 5 minutes then transfer to a wire rack to cool completely. 
  1. Make the Biscoff Buttercream Frosting. Follow the instructions in my post for Biscoff Buttercream.
  2. Decorate the Biscoff cookie butter cookies. Once the cookies have cooled, frost each cookie with the cookie butter frosting. Sprinkle with Biscoff cookie crumbs!

Recipe Tips

These copycat Crumbl Cookie Butter Cookies are typically served chilled if you buy them at Crumbl. I didn’t like them chilled. I thought they were much tastier when served at room temperature. 

Crumbl sprinkled the crumbs around the perimeter of the cookies if you want to do that to make them look just like the Crumbl cookie butter cookies. 

When you add the dry ingredients to the wet ingredients, do not over mix the cookie dough. If you do, the Biscoff butter cookies will be tough. You want a delicate and soft cookie so treat the dough as such! 

Use the creamy cookie butter to make the cookie butter buttercream. 

Make Ahead, Storing, and Freezing

To make ahead of time, make the cookie dough and store in an airtight container in the fridge for 1-2 days. Then remove and let come to room temperature before baking. 

You can store the frosting in an airtight container in the fridge for up to 7 days or in the freezer for 2-3 months. 

Store the frosted cookies in an airtight container in the fridge for 4-5 days or at room temperature for 1-2 days (room temperature if unfrosted. Frosting much be refrigerated due to the heavy cream).

Recipe FAQs

Are these cookie butter cookies served chilled?

Crumbl serves their cookie butter cookies chilled. But I wasn’t a big fan of them chilled! I thought these were much better when served at room temperature. 

Why isn’t there Biscoff butter in the cookies?

These Biscoff butter cookies are so named because of the delicious Biscoff frosting on top of the cookies, making them Biscoff butter cookies! I considered putting Biscoff spread in the cookies but I’ll tell you why I didn’t: The flavor just all blends together with the frosting. Having the cookie base be a brown sugar cookie actually complements the Biscoff flavor in the frosting instead of just blending together. Make these and you’ll see what I mean! 

Does Biscoff cookie butter spread go bad?

Like every food, there is a best by or expiration date so be sure to look at that.  

Does Biscoff cookie butter need to be refrigerated after opening?

Nope! Just like peanut butter, you can store cookie butter at room temperature.

  • 1 teaspoon molasses
  • 2 large eggs - at room temperature
  • 2 teaspoons vanilla extract
  • 3 1/4 cups all-purpose flour

  • 1/4 teaspoon salt
  • Biscoff cookies - crushed, for topping (optional)

Instructions
 

Cookies

  • Preheat the oven to 350°F. Line a baking sheet with parchment paper. 
  • Make the cookie dough: In a large bowl, or the bowl of a stand mixer fitted with a paddle attachment, beat the butter and brown sugar on medium speed for 2 minutes. Add the eggs and vanilla extract and mix to combine. Use a rubber spatula to scrape down the sides of the bowl. 
  • Add the flour, cornstarch, baking soda, baking powder, and salt and mix until just combined and the dough has come together. 
  • Portion the dough into ¼ cup sized balls. Place 6 dough balls on the prepared baking sheet. Use the palm of your hand to press down on each ball of dough just slightly to create a very thick disk. Bake for 11-13 minutes or until the edges are set and the centers no longer appear overly shiny or doughy.
  • Remove from the oven and let the cookies sit on the baking sheet for 5 minutes before transferring to a wire rack to cool completely. 

Cookie Butter Frosting

  • Make the frosting: In a large mixing bowl, or in the bowl of a stand mixer fitted with a paddle attachment, beat the butter for 2 minutes until light and fluffy. Add the Biscoff spread and mix on medium speed for 1 minute until light and fluffy. 
  • Add the powdered sugar and salt, mixing to combine. Scrape down the sides of the bowl with a rubber spatula. Add the heavy cream, a tablespoon at a time until the frosting reaches a smooth and spreadable consistency. Feel free to add more heavy cream, or more powdered sugar to reach your desired consistency. 

Assembly

  • Frost the cooled cookies with the cookie butter frosting. Sprinkle the crushed Biscoff cookie crumbs overtop of the frosting. (Crumbl sprinkled the crumbs around the perimeter of the frosted cookies). 

Notes

*note, crumbl serves these cookies chilled, but I did NOT like them chilled. I think they need to be enjoyed at room temperature.
