How to Make Cookie Butter Rice Krispies Treats (WATCH HERE)
Melt the Butter & Marshmallows: In a large saucepan over medium heat, melt the butter, stirring occasionally to prevent browning. Once fully melted, add most of the mini marshmallows, stirring constantly until completely smooth. Stir in vanilla extract and remove from heat.
Mix in the Good Stuff: Fold in the rice cereal, additional mini marshmallows, and crushed Biscoff cookies, stirring quickly to coat everything evenly before the mixture starts to set.
Shape the Treats: Transfer to a parchment-lined baking dish and gently press into an even layer, being careful not to compact them too much to maintain a soft, gooey texture.
Drizzle & Top: Melt the cookie butter and marshmallow fluff in the microwave in short intervals until smooth. Drizzle over the treats and sprinkle with extra crushed Biscoff cookies for a flavorful finishing touch.
Let Them Set & Slice: Allow the treats to cool at room temperature before cutting into squares.
Take It to the Next Level: For an indulgent twist, sandwich a scoop of vanilla bean ice cream between two pieces for the ultimate frozen treat. Enjoy immediately or freeze for a firmer bite. Allow to thaw a few minutes before diving in!
Storage & Reheating Tips
- Room Temperature: Store in an airtight container at room temperature for up to 3 days.
- Refrigerator: If you prefer a firmer texture, refrigerate for up to a week.
- Freezer: Wrap individual pieces in plastic wrap and freeze for up to a month. Let sit at room temperature for a few minutes before enjoying.
- For Ice Cream Sandwiches: Once assembled, wrap each sandwich in parchment paper and freeze until ready to enjoy.
These Cookie Butter Rice Krispies Treats are dangerously delicious on their own but even more irresistible when transformed into a creamy, crunchy ice cream sandwich. Whether you’re making them for a party, a cozy night in, or just because, this recipe is one you’ll keep coming back to!
Cookie Butter Rice Krispies Treats
Ingredients
- 6 ½ cups mini marshmallows divided
- 6 cups rice cereal
- 1 cup Lotus Biscoff cookies crushed, plus more for topping
- ¼ cup Biscoff cookie butter melted
- ¼ cup marshmallow fluff melted
- 8 tbsp unsalted butter
- 1 tsp vanilla extract
Optional
- Vanilla bean ice cream for serving
Instructions
- In a large saucepan over medium heat, melt the butter, stirring occasionally to prevent browning.
- Once fully melted, add 5 cups of mini marshmallows. Stir continuously with a silicone spatula until the marshmallows are completely melted and smooth.
- Add the vanilla extract and mix until incorporated. Immediately remove the pan from heat.
- Gently fold in the rice cereal, remaining 1 ½ cups of mini marshmallows, and 1 cup of crushed Biscoff cookies. Stir until the cereal is evenly coated in the marshmallow mixture, working quickly before it begins to set.
- Transfer the mixture to a parchment-lined baking dish. Using a spatula or greased hands, gently press it down into an even layer without compacting it too much—this keeps the treats soft and gooey.

- Drizzle the melted cookie butter and marshmallow fluff over the treats, then sprinkle with additional crushed Biscoff cookies for extra crunch and flavor.
- Let the treats cool at room temperature for at least 30 minutes before slicing into squares.
- Take it to the next level by sandwiching a scoop of vanilla bean ice cream between two pieces of the Rice Krispies treats for the ultimate frozen dessert. Press gently and enjoy immediately, or freeze for a firmer bite. Allow to thaw a few minutes before diving in!
