You are in for a REAL treat today. I think I might have created the best Rice Krispie Treats Recipe EVER! I know, that is a big statement, especially because I think our classic Rice Krispie Treats are PERFECT. But, let me introduce you to my new creation, Brown Butter Biscoff Rice Krispie Treats. WOW is right!

If you’ve been around awhile, you know I love Biscoff everything. Biscoff ice cream, Biscoff snickerdoodles, and Biscoff oatmeal cookies, just to name a few:) I am thrilled to add these Rice Krispie Treats to the list!

So I start with our classic Rice Krispie Treats recipe, but I brown the butter and boy is that a game changer. I also stir in Biscoff cookie butter which is similar to peanut butter in texture but has the flavor of Biscoff cookies (you know, the cookies you get on Delta). It is rich, creamy, and sweet!

I add lots of marshmallows so the treats are nice and gooey, a little sea salt, vanilla, Rice Krispies cereal, and chopped up Biscoff cookies.

The flavors are absolutely INCREDIBLE! Promise me you will make them!

Biscoff Rice Krispie Treat Recipes

Biscoff Rice Krispie Treats Ingredients

  • Butter– I use unsalted butter because I add sea salt to the recipe. Browning the butter brings out the most amazing flavor so don’t skip that step!
  • Marshmallows– use mini marshmallows not big marshmallows. You will need a 16 ounce bag AND 2 cups of mini marshmallows.
  • Biscoff cookie butter– you can find Biscoff spread at most grocery stores. Look by the peanut butter. You can also buy it online here. I prefer the Lotus brand, but Trader Joe’s cookie butter works well too!
  • Vanilla extract– just a splash!
  • Sea salt– sweet and salty is the best!
  • Rice Krispies Cereal– one box will do the trick!
  • Biscoff cookies– the cookies are nice and crunchy! Look for them in the cookie aisle at the grocery store. You can also purchase them here.
  • Flaky sea salt– for sprinkling on top, if desired!

How to Make Biscoff Rice Krispie Treats

The treats are no-bake and super easy to make! Maybe even too easy. I want to make them every week, ha! They are that good:)

  • You can make the Rice Krispie Treats in a 9×9-inch pan for super thick treats or you can make them in a 9×13-inch pan for regular Rice Krispie Treats. Make sure you grease the pan before getting started. You can also line the pan with parchment paper to make it easier for them to come out of the pan.
  • First, brown the butter. Place the butter in a large pot and melt over medium heat, stirring often, until it foams, smells nutty, and browns. This will take about 5 minutes.
  • Add the 16 oz bag of mini marshmallows and stir until the marshmallows are completely melted. Don’t over cook them or your RKT will end up hard.
  • Remove the pan from the heat and stir in the Biscoff cookie butter, vanilla extract and sea salt.
  • Add the Rice Krispies and chopped Biscoff cookies; gently stir until well coated with the marshmallows. Stir in the remaining 2 cups of mini marshmallows.
  • Lightly press the mixture into the pan, using a greased spatula. You can also lightly grease your hands and press the mixture into the pan. Don’t press too firmly or the treats will end up hard and dry. Sprinkle a little flaky sea salt on top, If desired.
  • Let them sit for a bit so they can set up, but if you want to dig right into a super gooey Rice Krispie Treat, I won’t tell. It’s hard to wait:)

How to Store

The Biscoff Rice Krispie Treats are best the day they are made, but you can wrap them tightly in plastic wrap or keep them in an airtight container on the counter for up to 3 days.

    I didnโ€™t have sea-salt, but I DID have half a bag of chocolate-covered pretzels sitting around, so I pressed those into the top of the mixture while it was still warm and sticky in the panโ€”worked amazingly.

  4. 5 stars
    These are insanely good. the Biscoff spread has a mild flavor presence so if you didn’t know it was there you might not be able to place it specifically, but you can tell these are not ordinary rice krispie treats; the flavor is so much deeper and richer. I bought two 10oz bags of mini marshmallows and rather than weigh/measure them out, I just decided to use all of them and I also used a little extra butter (maybe 9 or 10 tbs total) because I wanted these treats to be extra soft and rich. They were! Next time I make these I’ll add a tablespoon or two of good bourbon, which I’ve done in the past to my rice krispie treats and I highly recommend!
