Thick and chewy Biscoff Rice Krispie treats are the perfect nut-free lunch snack! Filled with cookie butter flavor, this easy no-bake dessert is made with just a few simple ingredients.
In a large pot, melt butter over medium-low heat. Once completely melted, add in all but 1 cup of mini-marshmallows and Biscoff spread. Mix continuously over low heat until marshmallow is smooth and creamy.
Quickly fold in cereal and remaining 1 cup of mini-marshmallows.
Pour in a buttered 8×8 pan (for thicker treats) or 13×9 pan (for thinner treats). Cover with plastic wrap. Allow to set at room temperature for about 1 hour.
Notes
Press gently: Use a light touch when patting the batter into the pan. The harder you press the tougher and firmer your Biscoff Rice Krispies will be!
For thinner Rice Krispie bars: Press the batter into a 9 x 13 baking pan.
For thicker Rice Krispie squares: Press the batter into an 8x8 square baking pan.
Use fresh marshmallows: That half empty bag that's been sitting open in your pantry since your last camping trip is not going to cut it. Grab a fresh unopened bag of marshmallows; it makes a big difference.
To store Biscoff Rice Krispie Treats: Transfer the squares to an airtight container. They'll keep well for about one week at room temperature.
