Here’s what you’ll need:

6 cups Rice Krispies cereal
1 (10 oz) bag mini marshmallows (about 5 ½ cups)

3 tablespoons unsalted butter
Pinch of salt

Instructions

These Biscoff Rice Krispie Treats come together in just minutes and don’t require any baking. Just melt, mix, press, and enjoy!

Step-by-step:

Prep your pan
Lightly grease an 8×8 or 9×9-inch baking dish with butter or line it with parchment paper for easy removal.
Melt the butter and marshmallows
In a large saucepan over low heat, melt the butter. Add the mini marshmallows and stir continuously until fully melted and smooth.
Add the Biscoff
Stir in the cookie butter and a pinch of salt until fully combined with the melted marshmallow mixture.
Mix in the cereal
Remove from heat and quickly stir in the Rice Krispies cereal until evenly coated.
Press into pan
Using a spatula (lightly greased to prevent sticking), press the mixture evenly into the prepared baking dish. Don’t pack too tightly—this keeps them soft and chewy!
Optional toppings
While still warm, drizzle extra melted Biscoff or sprinkle crushed Biscoff cookies over the top for added crunch and flair.
Cool and cut
Let the treats cool for about 30–45 minutes at room temperature. Cut into squares and enjoy!

Add a chocolate twist: Drizzle melted white or dark chocolate over the top for an extra layer of decadence.
Crumble on cookies: Press crushed Biscoff cookies into the top while the bars are still warm for added crunch and flavor.
Mix in mini Biscoff cookies: For texture, gently fold in a handful of mini cookies before pressing into the pan.
Go nutty: Add chopped pecans or almonds for a nutty contrast to the sweetness.
Salted finish: Sprinkle a pinch of flaky sea salt on top to balance the sweetness beautifully.
Make it dairy-free: Use plant-based butter and vegan marshmallows—just double-check they melt well.

Storage

Got leftovers? (Lucky you!) Here’s how to keep your Biscoff Rice Krispie Treats fresh and tasty:

Room temperature: Store in an airtight container at room temp for up to 4 days. Place parchment or wax paper between layers to prevent sticking.
Refrigerator: You can refrigerate them for longer shelf life (up to a week), but they’ll be firmer—just let them sit at room temp for 10 minutes before serving.
Freezer-friendly: Wrap individual squares in plastic wrap and store in a freezer-safe bag or container for up to 2 months. Thaw at room temp before eating.

Frequently Asked Questions

1. Can I use regular marshmallows instead of mini ones?
Yes! Just chop them into smaller pieces so they melt more evenly—use about 40 large marshmallows.

2. Is Biscoff the same as cookie butter?
Pretty much! Biscoff is a brand of cookie butter made from speculoos cookies. You can also use Trader Joe’s cookie butter or any similar spread.

3. Can I make these gluten-free?
Yes—just make sure your Rice Krispies cereal and cookie butter are labeled gluten-free.

4. What’s the best way to melt cookie butter?
Just pop it in the microwave for 15–20 seconds to make it easier to drizzle or stir in.

5. Can I double the recipe?
Absolutely! Use a 9×13-inch pan and double all the ingredients for a bigger batch.

6. Why are my treats too hard?
It usually means the mixture was packed too tightly or cooked too long. Be gentle when pressing into the pan and remove from heat as soon as everything’s melted.

7. Can I make these vegan?
Yes—use vegan marshmallows and a dairy-free butter alternative. Make sure your cookie butter is also plant-based (most are).
