No-Bake Oreo Bars

Have you ever had a Rice Krispy bar? These are Rice Krispy bars without the Rice Krispies. 😂 They are so easy to make, it would be a great recipe to get your kids involved. In addition, it’s a simple recipe to throw together for a potluck or anytime you need to bring a dessert or treat to share. The bars are made with just three ingredients and it is a no-bake dessert, so there is no need to turn on the oven!

Ingredients for Oreo Bars

Oreo Bar Ingredients

As I stated above, this recipe is made with just three simple ingredients! 

Oreos: I went with the double-stuffed Oreo cookies in this recipe and chopped them up with a knife, filling and all. Crushing them or using a blender would have made the pieces too fine. (But, if you wanted smaller crumbs in the bars, you could still add bigger chunks of Oreos on top.) You could also use regular stuffed Oreo cookies or a combination of the two. 

Marshmallows: I used a 10.5-ounce bag of mini marshmallows. If you use regular-sized marshmallows, you would need approximately 40 of them to equal the bag of mini marshmallows.

Butter: Use salted butter that is at room temperature.

Can I Use a Different Size Pan?

I made the Oreo Bars in an 8×8-inch baking dish. You could use a 9×9-inch pan if that is the smallest you have on hand. The bars will be a little thinner, but I don’t think anyone will complain; they will still be a tasty treat!

Can I Freeze Chewy Oreo Bars?

No, I would not recommend freezing these bars. The marshmallows in the dessert bars would not thaw well, resulting in a not-so-tasty treat. But, they are so easy to make, you could whip these up in no time when you are craving them or need a quick dessert.

  1. We don’t have double stuff Oreos where I live just regular. I was thinking that I would need to either use a bit more marshmallows or else a big spoon or two of vanilla frosting. What would be your best guess?

  2. After extensive searching and effort here are the results. Recipe as is yields a softer/chewier product falling on the very sweet side. Using regular Oreos yields a dryer/crunchier bar that is both less sweet and more chocolatie. Using regular Oreos and adding 3 generous tablespoons of vanilla frosting (I use homemade) to your melted marshmallows will result in bars closer to the texture and flavour of the original, but a bit more chocolate and a bit sweeter still. Finally, using regular Oreos but using an extra cup of marshmallows yields a soft/chewy more chocolatie but less sweet bar. I had no issues with freezing any of them, but don’t recommend eating them frozen.
