Apparently there are still people in my life that have never heard of Biscoff spread, aka Speculoos cookie butter, and it shocks me as it’s been a staple in my kitchen since 2011. It’s a food trend that has wavered over the years but it definitely has hung around enough that I thought it to be mainstream – evidently not.

I made these when friends came in town to visit Mother’s Day weekend (thank you for the distraction) and one of those friends is who I had to describe their flavor profile beyond “Biscoff” and “cookie butter”. They’re spiced but not just with cinnamon. From what I understand there is also nutmeg, cloves, cardamom, ginger, anise, and a bit of white pepper for that zing.

Thankfully you don’t need to know what Biscoff, or speculoos, or cookie butter is to enjoy these Biscoff rice krispie treats and the aforementioned friend devoured several of them. Similarly to my peanut butter version, there is cookie butter mixed into the melted marshmallow-butter mixture before blending in the puffed crispy rice cereal and chopped Biscoff cookies. For a little extra flavor and decoration I added a drizzle of cookie butter icing on top.
