Ingredients For Marshmallow Oreo Treats

Butter – The base of the recipe that helps bond and add flavor – make sure to use salted butter for best results!
Marshmallows – Once melted, this sticky goodness helps bind everything together!
Oreos – The heart and soul of the dish! Try different Oreo flavors to mix it up!

How To Make Marshmallow Oreo Treats

Prep: As with most stove-top “no-bake” treats, you’re going to want to move fast. So I highly recommend you measure out all of your ingredients beforehand and crush your Oreos so they are ready to go when you need them! You’ll also want to prep your pan!
Melt: The butter and marshmallow get melted together in a large pot until smooth. Make sure that your reserve some of the mini marshmallows for the end.
Mix: Once the marshmallows and butter have melted, remove from heat and add in the crushed Oreos and remaining marshmallows and stir to combine. I like to reserve a couple of tablespoons of crush Oreos to sprinkle over the top of the mixture after it goes in the pan.
Shape: Add the mixture to your prepared baking pan that’s been lined with parchment paper and use greased hands or another sheet of parchment paper to gently press the mixture into the pan.
Cool: Allow the treats to cool for at least 1 hour before cutting for best results.

How To Serve

Enjoy them as you would a Rice Krispies Treat! However, since these are made with Oreos, they are also really delicious when dipped in milk!

Can I Make These Treats Vegan?

While Oreos are a popular vegan treat, the butter and marshmallows are not. And this recipe has not been tested with vegan butter or marshmallow substitutes.

Why Are My Oreo Treats Hard?

Likely, you either cooked them over too high a heat or you pressed them into the pan too hard.
