How to make rice krispie treats:

Start by lining a 9"x9" pan with tin foil and spraying with baking spray.

Next, melt the butter over low/medium heat. Then add the marshmallows and stir constantly until juuust melted. Low and slow is best, cooking the marshmallows at too high a heat for too long will result in hard krispie treats.

Remove from heat immediately and stir in the vanilla.

Add in the puffed rice cereal, biscoff cookie crumbles, and cup of reserved marshmallows. Saving a few marshmallows for the end makes for little gooey marshmallow pockets in the rice krispie treats and it's amazing.

Mix until well combined, and add the cookie butter last. Mix it in gently so that there are pockets of it throughout the rice krispie mixture.

Lastly, press the mixture into the prepared 9"x9" pan. Sprinkle with a few extra biscoff cookie crumbles and let cool before slicing and serving.

And there you go! SO EASY.

How to freeze rice krispie treats:

Once the rice krispies are completely cool, wrap tightly in plastic wrap and then place in an airtight container and freeze for up to three months. When you're ready to eat them, make sure to thaw them at room temperature for 3-4 hours, don't put them in the oven or microwave or they will melt.
