Begin by gathering your ingredients for the Biscoff Rice Krispie Treats: marshmallows, Rice Krispies, butter, Lotus Biscoff spread, salt, and vanilla extract. Prepare an 8x8-inch baking pan lined with parchment paper.

In a medium saucepan, melt the butter over low heat. Add in the marshmallows and stir continuously until completely melted and smooth, about 3-5 minutes.

Remove from heat and quickly add the Rice Krispies, salt, and vanilla extract. Gently fold until well-coated.

Fold in the Lotus Biscoff spread until fully integrated, ensuring a light and airy texture.

Pour the mixture into the prepared pan, spreading evenly. Lightly press down to create a flat surface without over-compressing.

Allow the Biscoff Rice Krispie Treats to cool at room temperature for at least 1 hour before slicing into squares.
