Introduction

Discover the ultimate twist on a classic treat with these Biscoff Rice Krispie Treats. Combining the irresistible caramelized flavor of Biscoff spread and biscuits with gooey marshmallows, these squares deliver delight in every bite. Perfect for an easy dessert or a special snack!

A clear white bowl holds a dessert with three main parts: on the right, there is a neat stack of three square crispy rice treats that are beige with darker brown cereal pieces inside, showing a rough, airy texture. Surrounding the base of the stack and spreading around the bowl is a mixture of light tan puffed cereal and small chunks of dark brown cookie crumbles. In the center-left of the bowl, a thick, smooth, light brown creamy layer is being poured, folding over itself in soft waves with a shiny surface, sitting on top of the cereals. The background is a white marbled texture. photo taken with an iphone --ar 4:5 --v 7

Ingredients

90g (6 tablespoons) unsalted butter
280g (10-ounce) bag mini marshmallows, plus 1 cup (about 50g) extra
200g (roughly 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

Instructions

Step 1: Prepare a 9×9 inch (23×23 cm) square baking tin by lining it with baking parchment. Leave an overhang on two opposite sides for easy lifting. Lightly grease the parchment and any exposed tin areas with butter or cooking spray.
Step 2: In a large, heavy-based saucepan over low heat, gently melt the butter. Keep the heat low to prevent browning.
Step 3: Once the butter has melted, add the 280g bag of mini marshmallows and the smooth Biscoff spread. Stir constantly with a silicone spatula until the mixture is smooth and fully combined, maintaining low heat.
Step 4: Remove the saucepan from the heat. Stir in the vanilla extract and a pinch of sea salt to enhance the flavors.
Step 5: Add the Rice Krispies cereal and crushed Biscoff biscuits to the marshmallow mixture. Gently fold everything together with a greased spatula until evenly coated. Work quickly, as the mixture will start to firm up.
Step 6: Fold in the reserved cup of mini marshmallows with one or two gentle stirs to create soft, gooey pockets in the treats.
Step 7: Transfer the mixture to the prepared tin. Using a greased spatula or a piece of baking parchment, gently press it into an even layer without compacting too firmly.
Step 8: Let the treats set at room temperature for at least one hour before slicing to ensure clean, neat cuts.

Tips & Variations

Use low heat when melting marshmallows to avoid crystallization and keep the treats soft.
Adding extra mini marshmallows just before pressing into the tin creates delightful gooey pockets.
Press the mixture gently rather than firmly to maintain a light, chewy texture.
For a nutty twist, fold in chopped toasted pecans or almonds with the cereal and biscuits.
Swap Rice Krispies for gluten-free puffed rice cereal to make the treats gluten-free.

Storage

Store your Biscoff Rice Krispie Treats in an airtight container at room temperature for up to 3 days. They can also be wrapped individually for grab-and-go snacks. If stored longer, the treats may lose some of their softness but can be refreshed by warming them briefly in the microwave for 10–15 seconds.

How to Serve

A clear round bowl holds a mix of ingredients on a white marbled surface, with a thick, creamy, light brown sauce being poured into the center, forming a glossy, smooth mound with visible swirls. Around this creamy layer is a ring of pale, crunchy puffed rice scattered evenly, along with small clusters of crumbled darker brown bits sprinkled on top of and around the puffed rice. To the right side inside the bowl, three square, golden-brown, crispy cereal bars are stacked neatly, showing their airy, textured layers mixed with small darker pieces throughout. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use salted butter instead of unsalted?

Yes, salted butter can be used if that’s what you have on hand. Just be mindful of the added salt, as the recipe already includes a pinch of sea salt to balance the sweetness.

What if I don’t have Lotus Biscoff biscuits?

If you can’t find Lotus Biscoff biscuits, you can substitute with another spiced caramel biscuit or graham crackers crushed finely. This will still add a pleasant crunch and flavor without losing the essence of the recipe.
