Ingredients
Base Mixture
- 6 Tablespoons butter (85 g)
- 1 – 10 oz bag mini marshmallows
- ¾ cup + 2 Tablespoons Biscoff spread (210 g), also known as cookie butter spread
- 5 cups crispy rice cereal (150 g), such as Rice Krispies
- 10 pieces Biscoff cookies (80 g), roughly chopped
Optional Topping
- ¼ cup Biscoff spread (60 g)
Instructions
- Prep the Baking Pan: Line an 8-inch or 9-inch square baking pan with parchment paper, allowing excess paper to hang over the sides to assist with easy removal later. Set aside.
- Melt the Butter and Marshmallows: In a large pot, melt the butter over medium heat. Add the mini marshmallows and stir continuously until they have completely melted and the mixture is smooth. Reduce the heat to low.
- Add Biscoff Spread: Stir the Biscoff spread into the melted marshmallow mixture until it melts and is thoroughly combined, creating a creamy, spiced base.
- Combine with Cereal and Cookies: Remove the pot from heat immediately. Add the crispy rice cereal and roughly chopped Biscoff cookies, folding gently until all pieces are evenly coated with the marshmallow mixture.
- Press into Pan and Cool: Transfer the mixture into the prepared pan, pressing it down evenly to form a compact layer. Allow the treats to cool at room temperature for about 30 minutes, letting them set firmly.
- Unmold and Slice: Use the parchment paper overhang to lift the set treats from the pan onto a cutting board. Slice into desired serving sizes with a sharp knife.
- Optional Topping Drizzle: For an extra touch, place the leftover Biscoff spread in a microwave-safe bowl and heat in 10-15 second intervals, stirring between, until it becomes pourable. Drizzle this liquid Biscoff spread over the cut treats before serving.
Notes
- Ensure the marshmallows are melted completely for the perfect gooey texture.
- Press the mixture firmly into the pan to help the treats hold their shape.
- If using for gifting, wrap treats in parchment or wax paper to keep fresh.
- Biscoff spread can be quite thick; warming it gently before adding helps mixing smoothly.
- Store leftover treats in an airtight container at room temperature for up to 3 days.
