Introduction

These Ultimate Biscoff Rice Krispie Treats combine the nostalgic crunch of classic Rice Krispie squares with the rich, spiced flavor of Biscoff. Gooey, chewy, and bursting with layers of texture, they make an irresistible no-bake dessert perfect for any occasion.

A clear glass bowl on a white marbled texture surface contains four main parts: on the right, there are three square, layered crispy rice treats stacked vertically, showing a light beige color with dark brown spots mixed in; in the center, there is a smooth, thick, creamy light brown mixture being poured onto a base, creating swirled layers of glossy texture; around the base and creamy mixture, there is a scattered layer of puffed rice cereal and small dark brown crumbly pieces, creating a crunchy texture contrast. 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) reserved
200g (roughly ¾ cup) smooth Biscoff spread
180g (approximately 6 cups) Rice Krispies cereal
125g (around 16) Lotus Biscoff biscuits, crushed
1 teaspoon vanilla extract
A pinch of sea salt

Instructions

Step 1: 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 any exposed areas of the tin.
Step 2: In a large, heavy-based saucepan over low heat, gently melt the butter without browning it.
Step 3: Add the 280g bag of mini marshmallows and the smooth Biscoff spread to the melted butter. Stir constantly with a silicone spatula until the mixture is smooth and fully combined. Keep the heat low to avoid burning.
Step 4: Remove the saucepan from heat, then stir in the vanilla extract and a pinch of sea salt.
Step 5: Add the Rice Krispies cereal and crushed Biscoff biscuits to the marshmallow mixture. Gently mix until the cereal and biscuit crumbs are 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 pockets of gooey softness.
Step 7: Transfer the mixture to the prepared tin. Using a greased spatula or a piece of parchment, press the mixture down evenly but gently, avoiding compressing it too firmly.
Step 8: Allow the treats to set at room temperature for at least one hour before slicing for clean cuts.

Tips & Variations

Use fresh mini marshmallows for the best gooey texture; stale ones can make treats dry.
Avoid overheating marshmallows to prevent hard, brittle treats—keep the heat low and remove from heat as soon as melted.
Press the mixture gently into the tin to maintain air pockets and softness.
Drizzle melted white chocolate on top after setting for a creamy contrast.
Warm extra Biscoff spread and drizzle over the finished treats with crushed biscuits for an intensified flavor.
Add a chocolate layer by melting and spreading chocolate in the tin before pressing the mixture.
Mix in mini chocolate chips or butterscotch pieces for added flavor.

Storage

Store the sliced treats in an airtight container at room temperature for up to 3 days to maintain freshness and chewiness. Place sheets of baking parchment between layers to prevent sticking. Avoid refrigeration, which can cause the treats to harden and dry out. These treats freeze well — wrap individual squares tightly and freeze for up to 6 weeks. Thaw at room temperature for 15-20 minutes before serving.

How to Serve

A clear glass bowl sits on a white marbled surface, filled with a base layer of puffed rice cereal mixed with small crumbled brown bits spread evenly across. On the right side, there is a neat stack of three square rice cereal treats with visible puffed rice and brown specks, showing a slightly rough texture. On the left side, a smooth, thick layer of light brown, creamy peanut butter is being poured in a spiral from above, forming soft waves and adding a glossy shine to the center.
