Ingredients
Scale
Base
- 90g (6 tablespoons) unsalted butter
- 280g (10-ounce) bag mini marshmallows
- 1 cup (around 50g) mini marshmallows, reserved for folding in
- 200g (approximately ¾ cup) smooth Biscoff spread
- 1 teaspoon good-quality vanilla extract
- A pinch of sea salt
Add-ins
- 180g (about 6 cups) Rice Krispies cereal
- 125g (around 16 biscuits) Lotus Biscoff biscuits, crushed
Instructions
- Prepare Your Tin: Line a 9×9 inch (23×23 cm) square baking tin with baking parchment, leaving a slight overhang on two opposite sides for easy lifting. Lightly grease the parchment and exposed tin surfaces with butter or cooking spray.
- Melt the Base: In a large heavy-based saucepan over low heat, gently melt 90g of unsalted butter. Keep the heat low to prevent browning.
- Add Marshmallows and Biscoff: Add the entire 280g bag of mini marshmallows and 200g of smooth Biscoff spread to the melted butter. Stir constantly with a silicone spatula until the mixture is velvety smooth and fully combined, maintaining low heat.
- Incorporate Flavour Boosters: Remove the saucepan from the heat and stir in 1 teaspoon vanilla extract and a pinch of sea salt to enhance flavor.
- Combine with Crispies and Biscuits: Add the Rice Krispies cereal and crushed Biscoff biscuits to the marshmallow mixture. Gently fold with a greased spatula until everything is evenly coated. Work quickly as the mixture will begin to set.
- Add More Marshmallows (The Secret Step!): Fold in the reserved 1 cup of mini marshmallows with one or two gentle stirs to create pockets of gooey softness.
- Press into the Tin: Transfer the mixture into the prepared tin and lightly press it down evenly using a greased spatula or parchment. Avoid pressing too firmly to keep the treats light.
- Let It Set: Allow the treats to sit at room temperature for at least 1 hour to firm up before slicing into squares.
Notes
- Use fresh, soft marshmallows for the best gooey texture; stale marshmallows lead to dry treats.
- Keep the heat low when melting marshmallows to avoid crystallization and hard treats.
- Don’t press the mixture too firmly into the tin to maintain a light, chewy texture.
- Vanilla extract and a pinch of salt are crucial to balance sweetness and enhance flavor.
- Store treats in an airtight container at room temperature for up to 3 days; avoid refrigeration to prevent hardening.
- Treats can be frozen for up to 6 weeks wrapped individually in cling film and stored in a freezer-safe container.
- For extra Biscoff flavor, drizzle warmed Biscoff spread or melted white chocolate over set treats.
- To make them gluten-free, substitute with certified gluten-free crisped rice cereal and gluten-free Biscoff alternatives.
