What You’ll Need
Here are the ingredients you’ll need to make cake mix cookie bars at home. See the recipe card located at the bottom of the post for full details and instructions.
- Butter– In general, I use salted butter in my recipes. Unsalted is fine too.
- Yellow Cake Mix– Look for Pillsbury, Betty Crocker or Duncan Hines yellow cake mixes.
- Biscoff– find Biscoff, also called cookie butter, in the peanut butter section of the grocery store.
- Egg– I use large eggs in my cooking and baking for consistency.
- Chocolate Chips– If you can find mini chocolate chips, they work great. Regular size work just fine too.
- Sweetened Condensed Milk– Find sweetened condensed milk in the baking section of the grocery store. It’s used to make the sweet glaze that gets drizzled on top of the bars.
How To Make Cake Mix Bar Cookies
Preheat Oven. Preheat oven to 350 degrees F. and line a 9×13 inch baking pan with parchment paper.
Cake Mix Into Mixing Bowl. Place cake mix, melted butter, egg and Biscoff into a large mixing bowl.
Mix To Combine. Mix until dough forms and stir in chocolate chips.
Press Dough Into Pan. Press dough into prepared baking pan.
Bake. Bake for 25-28 minutes or until baked through. Let cool for 20 minutes.
Prepare Icing. To prepare icing, heat sweetened condensed milk and Biscoff spread into a small saucepan over medium low heat until creamy and thick. Remove from heat and let sit for 5 minutes. Pour over bars and cut into squares. Serve gooey or let icing set up.
Recipe Tips For Success
- Icing While Warm. Pour icing over bars while still warm for an extra gooey cookie bar.
- Parchment Paper. Make sure to use parchment paper lining your baking dish before baking. It makes removing bars nice and easy.
- Plastic Knife. I like to use a plastic knife to cut bars into squares. It cuts easy without sticking.
How To Serve
Serve these cake mix bar cookies warm cut into squares with gooey icing on top. You can even top with a scoop of vanilla ice cream.
Leftovers
Serve any leftover cookie bars in an airtight container in the refrigerator for up to 3-4 days.

Where do I find the Biscoff spread? I love the Biscoff cookie but have never heard of the spread.
These look fantastic! Question – does the glaze set up after a while or stay gooey?
I made these over the weekend and they are heaven!! I am a huge fan of anything biscoff!
I actually made them without the topping because i mailed them to my Dad as part of a birthday gift.
Do the bars need to be refridgerated if the topping is used?
This might be an odd question, but how many ounces/weight of the cake mix? I have quite a stock of homemade cake mixes (I have celiac and refuse to spend $8 on a gritty poorly flavored store bought cake mix, so every few months I take a day and make a dozen or so ‘dump & go’ bags for quick desserts. A quarter of the price and 100x better tasting!) to use, and this looks like a perfect switchup once I know what size/amount to start from. And serendipitously, one of my baking projects this week is to make a knockoff biscoff cookie and then use those to make a GF knockoff of the biscoff spread. Proof the universe WANTS me to have these bars! Thanks also for all the amazing work you do both here on the site and in your book. You do really a wonderful job with both!
This looks mouth wateringly delicious! Yummy!
I’m going to buy the ingredients this moment.

what is biscoff spread? is it just peanut butter?
I am from ontario in canada.
Hi Judy,
Biscoff spread is made from cookies with the same consistency as peanut butter. It has a cinnamon graham cracker taste if you ask me 🙂 It’s delicious! You can try ordering it on Amazon.com.
