The Story Behind This Recipe

I have a soft spot for recipes that feel nostalgic but still a little over the top. Rice Krispy treats are one of those desserts almost everyone remembers from childhood, but adding melted Biscoff spread completely changes the game.

The first time I tested this Biscoff version, I knew it needed more Biscoff flavor in the topping. The creamy cookie butter gets mixed with white chocolate and turns these into one of those bakery-style treats people immediately ask about after one bite.

If you’re a Biscoff lover, this might become your new favorite easy Biscoff recipe.

What Does Biscoff Taste Like?

If you’ve never baked with Lotus Biscoff biscuits before, the flavor is hard to describe until you try it. The unique taste of Lotus Biscoff is warm, spiced, buttery, and slightly caramelized all at the same time. It reminds some people of speculaas cookies or graham crackers with a deeper caramel flavor.

Biscoff cookie butter is made by blending those famous lotus cookies into a smooth spreadable consistency similar to peanut butter or chocolate spread. You can usually find it near the peanut butter aisle at the grocery store, Trader Joe’s, or online.

That rich Biscoff flavour is what makes these bars feel extra indulgent even though they use such simple ingredients.

How to Make Biscoff Rice Krispy Treats

1. Prepare the pan

Line an 8x8 pan with parchment paper, leaving extra hanging over the sides for easy removal later.

2. Melt the marshmallow mixture

In a medium saucepan over medium heat, melt the butter and mini marshmallows together. Stir often until smooth and fully melted.

3. Add the Biscoff spread

Stir in the melted Biscoff spread until completely combined. The mixture should look glossy and smooth with a warm caramel color.

4. Fold in the Rice Krispies

Turn off the heat and immediately add the Rice Krispies cereal. Stir until every piece is evenly coated.

5. Press into the pan

Transfer the mixture to the prepared pan. Lightly press it down into an even layer. Do not pack it too firmly or the treats can become dense.

6. Add the topping

Pour the melted white chocolate over the top, followed by the melted Biscoff spread. Use a spoon or knife to gently swirl the two together.

Refrigerate until set, then lift from the pan and cut into squares.

Allyson’s Tips

If you want an even more indulgent treat, crush Lotus Biscoff cookies on top before refrigerating.

Storage & Make-Ahead Tips

Store the bars in an airtight container at room temperature for up to 3 days.

For a firmer texture, refrigerate them and let them sit at room temperature for 10 minutes before serving.

These also freeze surprisingly well. Wrap individual bars tightly and freeze for up to 1 month.

Ingredients

▢ 5 tablespoon butter 70g
▢ 4 cups mini marshmallows 200g
▢ ¾ cup Biscoff spread, melted 200g
▢ 5 cups Rice Krispies cereal 150g
▢ 1 cup white chocolate, melted 200g
▢ ¼ cup Biscoff spread 75g

Instructions

Line an 8x8 pan with parchment paper, leaving enough extra parchment hanging over the sides so you can easily lift the bars out later. Lightly spray the parchment with nonstick spray if desired.
In a medium saucepan over medium heat, melt the butter and mini marshmallows together. Stir frequently with a silicone spatula until the mixture is completely smooth and no marshmallow lumps remain. Be careful not to overheat the mixture or the treats can become hard instead of soft and chewy.
Add the melted Biscoff cookie butter spread to the marshmallow mixture and stir until fully combined. The mixture should look glossy, creamy, and light caramel in color with that warm spiced Biscoff flavour.
Remove the pan from the heat and immediately fold in the Rice Krispies cereal. Stir gently until every piece of cereal is evenly coated. Work fairly quickly here so the mixture does not start to set before pressing it into the pan.
Transfer the mixture to the prepared pan. Use a lightly greased spatula or piece of parchment paper to gently press the cereal mixture into an even layer. Do not firmly pack it down or the bars can turn dense and hard instead of light and gooey.
Melt the white chocolate in a microwave-safe bowl in 20 second intervals, stirring between each interval until smooth. Pour the melted white chocolate evenly over the top of the bars.
Warm the remaining Biscoff spread until it reaches a smooth pourable consistency. Drizzle it over the melted white chocolate, then use a knife or skewer to gently swirl the two together for a bakery-style finish.
Refrigerate the bars for about 30 minutes or until fully set. Lift the bars from the pan using the parchment paper handles, then slice into squares with a sharp knife. For the cleanest cuts, wipe the knife between slices.

Notes

Do not over-press the cereal mixture into the pan or the bars can become hard.
Slightly greasing your spatula helps prevent sticking.
These bars are easiest to cut once fully chilled.
Use smooth cookie butter spread for the best texture and pourable consistency.
