Ingredients

Scale

Base Ingredients

  • 90g (6 tablespoons) unsalted butter
  • 280g (10-ounce) bag mini marshmallows
  • 200g (¾ cup) smooth Biscoff spread
  • 180g (approximately 6 cups) Rice Krispies cereal
  • 125g (around 16) Lotus Biscoff biscuits, crushed
  • 1 teaspoon good-quality vanilla extract
  • A pinch of sea salt
  • Additional 50g (1 cup) mini marshmallows reserved for folding in

Instructions

  1. Prepare Your Tin: Line a 9×9 inch (23×23 cm) square baking tin with baking parchment, allowing overhang on two opposite sides for easy removal later. Lightly grease the parchment and any exposed tin areas with butter or a neutral cooking spray.
  2. Melt the Base: In a large, heavy-based saucepan or Dutch oven, melt 90g of unsalted butter over low heat carefully, avoiding browning.
  3. Add Marshmallows and Biscoff: Once the butter is melted, add the full 280g bag of mini marshmallows and 200g of smooth Biscoff spread. Stir constantly over low heat with a silicone spatula until the mixture is velvety smooth and fully combined, taking care not to overheat.
  4. Incorporate Flavour Boosters: Remove the saucepan from the heat, then promptly stir in 1 teaspoon of vanilla extract and a pinch of sea salt to enhance flavor complexity.
  5. Combine with Crispies and Biscuits: Add 180g Rice Krispies cereal and crushed 125g Lotus Biscoff biscuits to the marshmallow mixture. Gently but thoroughly fold with a greased spatula until everything is evenly coated, working quickly as the mixture will begin to set.
  6. Add More Marshmallows (The Secret Step!): Fold in the reserved 50g (1 cup) mini marshmallows with just one or two stirs to create delightful pockets of gooey softness within the treats.
  7. Press into the Tin: Transfer the mixture carefully into the prepared tin. Use a greased spatula or a piece of parchment paper to gently press it into an even layer without compressing too firmly, preserving the treats’ light texture.
  8. Let It Set: Allow the treats to rest at room temperature for at least one hour until firm enough for clean slicing.

Notes

  • Use low heat to prevent marshmallows from overheating and becoming hard or brittle.
  • Do not press the mixture too firmly into the tin to avoid dense, hard treats.
  • Reserve some mini marshmallows to fold in at the end for extra gooey texture pockets.
  • Lining the baking tin with parchment overhang makes it easy to lift out the set treats for slicing.
  • Ensure all ingredients are ready before starting, as the mixture sets quickly once combined.
