Biscoff Rice Krispie Treats (Printable)

No-bake Biscoff squares with melted marshmallows and crispy cereal; sweet, chewy bites ideal with coffee.

# What You'll Need:

→ Base

01 - 3 tablespoons unsalted butter
02 - 1 cup Biscoff spread
03 - 6 cups Rice Krispies cereal
04 - 4 cups mini marshmallows

→ Topping

05 - 1/4 cup Biscoff spread, melted
06 - 1/3 cup crushed Biscoff cookies (optional)

# Steps:

01 - Line a 9x9-inch square pan with parchment paper and lightly grease the surface to prevent sticking.
02 - In a large saucepan over low heat, melt the unsalted butter. Add Biscoff spread and stir continuously until the mixture is smooth and fully blended.
03 - Add mini marshmallows to the saucepan. Cook over low heat, stirring constantly, until the marshmallows are completely melted and incorporated.
04 - Remove the saucepan from heat. Gently fold in the Rice Krispies cereal until each piece is thoroughly coated with the marshmallow-Biscoff mixture.
05 - Transfer the mixture into the prepared pan. Using a lightly greased spatula or wax paper, press the mixture evenly and gently into the pan to form an even layer.
06 - Drizzle the melted Biscoff spread over the top and sprinkle with crushed Biscoff cookies if desired.
07 - Allow to cool at room temperature for about 45 minutes, or until completely set. Cut into 16 equal squares before serving.

# Expert Tips:

01 -
  • The Biscoff elevates an old-school favorite into pure caramelized bliss—the kind you’ll want to sneak before anyone else arrives.
  • With just five ingredients and almost no prep, it’s a foolproof treat for every craving or sudden guest.
02 -
  • One time I tried to rush and slice while still warm—total sticky disaster, so patience pays off here.
  • Once I chilled the pan for thirty minutes: the result was cleaner cuts and a delightful, chewier bite.
03 -
  • A greased offset spatula lets you get perfectly smooth tops without sticking to your hands.
  • Melting the Biscoff spread for the drizzle in 5-second microwave bursts prevents scorching and keeps it pourable.
