So yummy. So easy to make. And chock full of the warm spicy flavor that cookie butter is known for.  Enjoy!

Step 10: Spoon the mixture into a 9×13″ pan. We line our pan with parchment paper.
Step 11: Lightly press the mixture into the pan.  You don’t want to press the mixture down too compactly, just smooth the top with a spatula or butter your fingers and pat down the top.
Step 12: Sprinkle fine Biscoff Cookie Crumbs on the top of the treats. (Optional)

Serving/Storage Instructions

Rice Krispie Treats will last 2-3 days at room temperature in an air-tight container before they start to get stale.  You can extend that timeline a few days if you store them in the refrigerator and then take them out about 30 minutes before you eat them.  They freeze up great though and that is what we do if we want to make these ahead of time for a party or a family gathering.  They defrost very quickly and taste great once they are defrosted.  You can keep them in the freezer for up to a couple of months.
