Introduction

Discover the ultimate twist on a classic treat with these Biscoff Rice Krispie Treats. Combining the beloved crunch of Rice Krispies with the rich, spiced flavor of Biscoff spread and biscuits, these no-bake squares are irresistibly gooey and crunchy.

In a clear white bowl, there is a base layer of light puffed rice cereal mixed with small brown crumbly bits. On top of this base, a smooth, thick, creamy layer of light brown mixture is being poured in folds from above, forming a rounded mound in the center. To the right side of the bowl, three square cereal bars with a pale beige color and visible brown specks are stacked neatly in a small tower. The bowl is placed on a white marbled surface. 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 (around 50g) extra
200g (about ¾ cup) smooth Biscoff spread
180g (approximately 6 cups) Rice Krispies cereal
125g (about 16) Lotus Biscoff biscuits, crushed
1 teaspoon 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, leaving an overhang on two sides for easy lifting. Lightly grease the parchment and any exposed tin areas with butter or neutral cooking spray.
Step 2: In a large, heavy-based saucepan over low heat, gently melt the butter without allowing it to brown.
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 completely smooth and combined. Keep the heat low to avoid burning.
Step 4: Remove the pan from heat and stir in the vanilla extract and 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 until evenly coated. Work quickly as the mixture will start to set.
Step 6: Fold in the reserved 1 cup of mini marshmallows with only one or two stirs. These will create soft pockets inside the treats for extra gooeyness.
Step 7: Transfer the mixture into the prepared tin. Using a greased spatula or parchment, gently press the mixture into an even layer without compressing it too tightly.
Step 8: Allow the treats to set at room temperature for at least one hour to firm up before slicing and serving.

Tips & Variations

For a richer flavor, try using salted butter but reduce additional salt in the recipe accordingly.
Swap Rice Krispies for a gluten-free puffed rice cereal if you need a gluten-free option.
Mix in chopped nuts or chocolate chips for added texture and flavor variety.
Press the mixture gently to keep the treats light and airy rather than dense.

Storage

Store your Biscoff Rice Krispie Treats in an airtight container at room temperature for up to 3 days. To keep them fresh longer, refrigerate for up to a week, but allow them to come to room temperature before eating for the best texture. Avoid freezing as it can affect the marshmallow consistency.

How to Serve

A clear bowl holds three layers of different textures and colors. The bottom layer is small, puffy, beige-colored cereal pieces spread evenly at the base. On top of and mixed with the cereal are rough, dark brown crumbled pieces scattered around the bowl. The main layer in the center is a smooth, swirl of shiny light brown cream being poured from above, creating a soft, thick mound. To the right, three square crispy rice treats with light beige and darker brown spots are stacked neatly on top of each other. The background and surface are a white marbled texture. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use crunchy Biscoff spread instead of smooth?

Yes, but smooth Biscoff spread blends more evenly into the marshmallow base, giving a better texture. Crunchy spread will add small bits of cookie but might affect the smoothness slightly.

What if I don’t have Lotus Biscoff biscuits?

You can substitute with any cinnamon-spiced cookies or graham crackers crushed into small pieces. While the flavor will differ, the added crunch and warmth will still enhance the treats.
