The Story Behind This Recipe

Confession time: I’m a little obsessed with Rice Crispy Treats. I spent way too many weekends tinkering with marshmallow-to-cereal ratios to find the perfect chewy-but-not-sticky balance. After testing (and eating) about 20 versions — tough job, I know — I finally cracked the code.

And then I had a thought: “What if I took that perfect base and gave it a speculoos glow-up?” Enter: Biscoff Cookie Butter. A swirl of this golden, spiced spread turned an already-perfect treat into something completely drool-worthy.

Ingredients You’ll Need

Here’s what makes these Baking Sweets so darn good:

• Butter: Go for salted butter if you can — it keeps the sweetness in check and adds flavor depth.
• Biscoff Cookie Butter: The star of the show. Half a cup is just enough to flavor the whole batch without making them too soft.
• Marshmallows: Mini marshmallows melt faster and give you that gooey, glossy texture we all love.
• Rice Krispies Cereal: Kellogg’s classic is my go-to, but any crispy rice cereal works.
• Biscoff Cookies: Crumbled into the mix and sprinkled on top for extra crunch and spice.

How to Make Gooey Biscoff Rice Krispie Treats

Let’s keep it simple — because honestly, these Yummy Sweets should be fun, not stressful:

1. Melt the Magic: In a saucepan, melt butter and Biscoff cookie butter together over low heat. Stir until smooth and fragrant.
2. Add Marshmallows: Toss in your marshmallows and stir until mostly melted. (Pro tip: pull the pan off the heat when 75% are melted and stir until the rest catch up — this keeps them soft and silky.)
3. Mix It Up: Butter a big mixing bowl and add your cereal + cookie chunks. Pour the gooey mixture over and stir until everything is coated.
4. Press & Sprinkle: Press into a greased 8×8 or 9×9 pan (don’t squish too hard, you want them chewy). Sprinkle more cookie crumbs on top.
5. Cool & Slice: Let them sit for about an hour… or, if you have zero chill like me, cut into them while they’re still warm and gooey.

Pro Tips for the Best Results

• Butter Everything: Your pan, your spatula, even your hands if needed. It keeps the mixture from sticking and makes life easier.
• Low & Slow: Melt your butter and marshmallows on low heat. High heat can make them hard instead of gooey.
• Cereal Ratio Matters: The sweet spot here is 5 cups cereal to 10 ounces marshmallows. Too much cereal = dry bars. Too little cereal = sticky mess.

FAQs

Can I make these in the microwave?
Yes! Combine the butter, cookie butter, and marshmallows in a large bowl and microwave for 1 minute. Stir until melted, then proceed with the recipe.

Do I have to use Biscoff brand?
Nope! Any speculoos cookie butter works. Trader Joe’s makes a great one, too.

What’s the trick to gooey but not sticky treats?
Don’t overcook the marshmallows and stick to the cereal-to-marshmallow ratio above. Too much heat = tough bars.
