Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
unsalted butter mini marshmallows Biscoff cookie butter spread vanilla extract salt Rice Krispies cereal extra marshmallows (optional for extra gooey texture) Biscoff cookies, crushed (optional topping)
Directions
Prepare a 9×13-inch baking pan by lining it with parchment paper or lightly greasing it with butter.
Place the butter in a large saucepan over medium heat. Allow it to melt and continue cooking, stirring frequently, until it begins to foam and develop golden brown bits with a nutty aroma. This is the browned butter.
Lower the heat and add the marshmallows to the browned butter. Stir continuously until the marshmallows melt completely and the mixture becomes smooth.
Stir in the Biscoff spread, vanilla extract, and salt until fully combined and creamy.
Remove the saucepan from heat and immediately fold in the Rice Krispies cereal. Stir gently until all the cereal is evenly coated.
If using extra marshmallows, fold them in at this stage for pockets of gooey texture.
Transfer the mixture into the prepared pan. Press it down gently with a spatula or buttered hands to create an even layer. Avoid pressing too firmly so the treats stay soft.
Sprinkle crushed Biscoff cookies on top if desired.
Allow the treats to cool and set at room temperature for about 30–45 minutes before cutting into squares.
Servings and timing
Servings: 12–16 squares
Prep time: 10 minutes Cook time: 10 minutes Cooling time: 30–45 minutes Total time: about 50–60 minutes
Variations
Chocolate drizzle Melt some chocolate and drizzle it over the top of the finished treats for a rich chocolate-Biscoff combination.
Biscoff swirl topping Warm extra Biscoff spread slightly and drizzle it across the top before the treats fully set.
Salted caramel version Add a drizzle of caramel sauce and a sprinkle of flaky sea salt for a sweet-salty twist.
Stuffed treats Press half the mixture into the pan, spread a thin layer of Biscoff spread, then top with the remaining cereal mixture.
White chocolate mix-in Stir white chocolate chips into the mixture after it cools slightly for creamy sweetness.
Storage/Reheating
Store the treats in an airtight container at room temperature for up to 3 days. Keeping them tightly sealed helps maintain their soft and chewy texture.
For longer storage, refrigerate them in an airtight container for up to 1 week. Let them sit at room temperature for a few minutes before serving so they soften.
These treats can also be frozen for up to 2 months. Wrap each square individually in plastic wrap and place them in a freezer-safe container. Thaw at room temperature before eating.
Reheating is usually unnecessary, but if they become firm, a few seconds in the microwave will restore softness.
FAQs
What does browning the butter do?
Browning the butter caramelizes the milk solids, giving the treats a deeper, nutty flavor that makes them taste richer than traditional Rice Krispie treats.
Can I use regular marshmallows instead of mini marshmallows?
Yes, regular marshmallows work just as well. They may just take slightly longer to melt.
What is Biscoff spread?
Biscoff spread is a creamy spread made from spiced caramelized cookies, often called cookie butter. It has a warm, sweet flavor similar to caramel and cinnamon.
Can I make these treats gluten-free?
Yes, simply use gluten-free crispy rice cereal and ensure the cookie butter brand you use is certified gluten-free.
Why are my Rice Krispie treats hard?
They may have been pressed too firmly into the pan or cooked too long. Gentle pressing and removing the marshmallow mixture from heat quickly helps keep them soft.
Can I double the recipe?
Yes, you can double the recipe and use a larger baking pan or two standard pans.
Can I add chocolate chips?
Yes, but allow the mixture to cool slightly before adding them so they don’t melt completely.
How do I keep the treats from sticking?
Lightly grease your spatula or hands with butter or cooking spray when pressing the mixture into the pan.
Can I make these ahead of time?
Yes, they can be made a day or two ahead and stored in an airtight container until ready to serve.
Can I use crunchy Biscoff spread?
Absolutely. Crunchy Biscoff spread adds extra texture and a little crunch to the treats.
