    Jenny it’s great to see a cakemix bar recipe from you. I feel like it’s been awhile – and I love all your bar recipes. And Biscoff- you’re right, there will be NONE of these babies left over if you take them to a potluck or an event. I’d love one right now! Pinned!

    Not only was I starting to itch and twitch from baking withdrawal but I have Biscoff spread that’s been mocking me for days in my kitchen pantry. Thank YOU so much for this very delicious-looking (and I’m sure it will be!!) dessert that is going to be my saving grace. I cannot wait to race home tonight and make this!

    These look fabulous, Jenny! Quick question: is it possible to use PB as a substitute for cookie butter or Biscoff? We don’t get either in Canada!

      Someone else here asked if they can use Peanut Butter so that would be a good substitute. I’d love to hear if that works out for you. Enjoy!!

      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 ๐Ÿ™‚ It’s delicious! You can try ordering it on

    […] newbie or two. This time around one of the newbies was Gooey Biscoff Chocolate Chip Cake Bars from Picky Palate. The minute I saw them on Jennyโ€™s site the tug of war began. Make them, donโ€™t make them, make […]

    I’m going to buy the ingredients this moment.

    This looks mouth wateringly delicious! Yummy!

    Jenna says:

    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!

    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?

    brittany k says:

    These look fantastic! Question – does the glaze set up after a while or stay gooey?
