How to Make Biscoff Rice Krispie Treats
-
Prepare: Start by greasing a large mixing bowl and an 8-inch or 9-inch square pan with butter or cooking spray. This ensures your treats won’t stick, making for easy removal later.
-
Mix Cereal and Cookies: Pour Rice Krispies Cereal into the greased mixing bowl. Gently mix in 6 broken Biscoff Cookies for that delightful crunch and flavor within your treat.
-
Melt Butter: In a medium saucepan, melt the salted butter and Biscoff Cookie Butter over low heat. Stir occasionally until smooth and well-combined; this should take about 3-4 minutes.
-
Add Marshmallows: Once the butters are melted, add in the marshmallows. Stir until they’re about 75% melted, then remove from heat; continue stirring until fully melted and glossy—no lumps allowed!
-
Combine: Pour the melted mixture over the Rice Krispies and Biscoff Cookies. Gently mix until everything is well-coated and sticky; this is where the magic happens!
-
Press into Pan: Transfer the mixture to the greased pan. Use a spatula or your hands (lightly greased) to press it down evenly, ensuring it fills all corners.
-
Top with Cookies: Sprinkle the remaining Biscoff cookie pieces on top and press them down gently so they adhere to the surface. This adds an extra crunch with each bite!
-
Cool: Let the pan cool for at least 30 minutes at room temperature before cutting into 16 neat squares. This cooling time helps the treats firm up for easy slicing.
Optional: Drizzle with chocolate for an extra layer of indulgence before they cool.

How to Store and Freeze Biscoff Rice Krispie Treats
Room Temperature: Store Biscoff Rice Krispie Treats in a cool, dry place in an airtight container for up to 5 days to maintain their chewy texture.
Fridge: For longer freshness, keep the treats in the fridge, which can extend their life to about 7 days; just make sure they are tightly sealed to avoid absorbing moisture.
Freezer: Freeze your Biscoff Rice Krispie Treats by individually wrapping them in plastic wrap and placing them in a freezer-safe bag for up to 2 months. Thaw at room temperature before enjoying.

Biscoff Rice Krispie Treats Recipe FAQs
How do I select the right Biscoff cookies and cookie butter?
Absolutely! When choosing Biscoff cookies, look for those that are crisp with a rich, spiced flavor. For cookie butter, aim for a creamy texture that’s free of additives. If you find the classic Biscoff not available, any similar spiced or ginger cookies make a great substitute.
How should I store my Biscoff Rice Krispie Treats?
Very simple! Keep the treats in an airtight container at room temperature if consuming within 5 days. For extended freshness, you can refrigerate them, which will keep them good for up to 7 days—just ensure they are sealed tightly to prevent moisture.
Can I freeze Biscoff Rice Krispie Treats?
Yes, you can! To freeze, individually wrap each square in plastic wrap and then place them in a freezer-safe bag. They’ll stay fresh for up to 2 months. When you’re ready to enjoy them, simply thaw at room temperature or warm slightly in the microwave for a few seconds.
What if my marshmallows don’t melt completely?
Oh no! If your marshmallows aren’t melting smoothly, return the pan to low heat and stir continuously. Aim for a glossy, lump-free mixture. If you’ve had the heat too high, remove it from the heat right away to prevent burning and keep stirring until fully melted.
Are there any dietary considerations for my treats?
The more the merrier! If you’re catering to allergies, ensure there are no cross-contaminants with the Biscoff cookies as they contain wheat and may have traces of nuts. For a dairy-free option, substitute the butter with coconut oil and use dairy-free marshmallows. Always check labels to stay safe!
How long will my Biscoff Rice Krispie Treats last?
You’ll love that these sweet treats stay delicious! At room temperature, they’ll remain fresh for about 5 days, but refrigerating them can extend their shelf life to 7 days. Just remember to keep them sealed!
