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
- Pinch of sea salt
- Additional 50g (about 1 cup) mini marshmallows reserved for folding in
Instructions
- Prepare Your Tin: Line a 9×9 inch (23×23 cm) square baking tin with baking parchment, allowing a slight overhang on two opposite sides for easy lifting. Lightly grease the parchment and any exposed tin areas with butter or neutral cooking spray to prevent sticking.
- Melt the Base: In a large, heavy-based saucepan or Dutch oven, gently melt 90g of unsalted butter over low heat. Keep the heat low to prevent browning or burning.
- Add Marshmallows and Biscoff: Once the butter has melted completely, add the entire 280g bag of mini marshmallows and 200g of smooth Biscoff spread. Stir continuously with a silicone spatula over low heat until the mixture is fully melted, smooth, and combined without scorching.
- Incorporate Flavour Boosters: Remove the saucepan from the heat. Quickly stir in 1 teaspoon vanilla extract and a pinch of sea salt to enhance and balance the sweetness and flavor depth.
- Combine with Crispies and Biscuits: Add the 180g Rice Krispies cereal and the crushed 125g Biscoff biscuits into the marshmallow mixture. Gently mix everything together with a greased spatula until the cereal and biscuit pieces are evenly coated. Work swiftly as the mixture begins to firm up.
- Add More Marshmallows (The Secret Step!): Fold in the reserved 50g (about 1 cup) of mini marshmallows with one or two gentle stirs. These won’t fully melt and will create pockets of gooey softness in the finished treats.
- Press into the Tin: Carefully transfer the mixture into your prepared tin. Using a greased spatula or another piece of parchment, gently press the mixture into an even layer. Avoid pressing too firmly to keep the treats light and chewy.
- Let It Set: Allow the treats to set at room temperature for at least one hour before slicing. This resting period ensures firm, clean cuts and the best texture.
Notes
- Use mini marshmallows for quicker, more uniform melting compared to large marshmallows.
- Keep the heat low throughout to avoid sugar crystallization, which leads to hard treats.
- Press the mixture lightly to avoid dense, hard textures; gentle pressing keeps the treats chewy.
- The reserved marshmallows add delightful soft pockets inside the treats.
- Line your baking tin with parchment with an overhang to easily lift out the treats once set.
