Cookies and Cream Rice Krispies Treats

These is just something so perfect about rice krispies treats!  They’re quick and easy to make, sweet, crunchy and can be adjusted countless ways!  I’ve posted delicious variations of rice krispies treats before, including S’mores Rice Krispies Treats (amazingly delicious!!), Caramel Turtle Rice Krispies Treats (chocolate and caramel… need I say more), as well as these cute and easy Spring Rice Krispies Treats.  I’ve been craving rice krispies treats (here’s my Rice Krispies Treats Pinterest board!) and thought it was time to try another variation.  This Cookies and Cream version is so easy, and so delicious!  My girls loved helping to make them and eat them… and I enjoyed far more than my fair share as well!

Cookies and Cream Rice Krispies Treats

6 cups Rice Krispies cereal

20 regular oreos, crushed/chopped (about 2 1/2 cups crushed)

5 cups mini marshmallows

3 Tablespoons butter


1.  Put rice krispies treats into a large bowl.  Spray a 9×13″ casserole dish or cake pan with non-stick spray, set aside.

2.  In a large plastic (ziplock type) bag, crush oreos (I used a large, flat bottom mug).  You want to have some crushed into small pieces, and some bite size chunks.  Add oreos to rice krispies and stir to combine.

3.  In a large microwave safe bowl, heat butter and marshmallows together (about 3 minutes).  They will expand a LOT, so make sure your bowl is big enough.  When the marshmallows are puffy and mostly melted, carefully remove from microwave and stir to fully combine the butter, and make sure the marshmallows are fully melted.  *Note you are welcome to do this step in a large pot on the stove if you prefer.

4.  Pour melted marshmallows over cereal and oreos and use a spatula sprayed with non-stick cooking spray to quickly combine all the ingredients.  As soon as all the cereal is combined, spread mixture into the prepared 9×13″ dish.  Use the spatula to press the mixture around the dish, and flatten as needed.

5.  Allow to cool (about 20 minutes) before cutting into squares.  Eat and enjoy!

Yield- About 24 (2 inch) squares.

Storage- Keep covered with plastic wrap, or in an airtight container 2-3 days.

Variations-  This recipe was the third batch I made over a two day trial… the first batch I was sure would be delicious and was topped with a thin layer of melted white chocolate and topped with additional oreos.  But my husband and I voted that the white chocolate was a bit over powering for these, but if you love white chocolate, feel free to try them this way.  My second try included melting some additional marshmallows to spread over the top in order to adhere some chopped oreos.  While these were delicious, they were a little too gooey.  The final recipe (as listed above) is the simplest, but our (family) favorite.

Recipes source-  I’ve been dreaming up fancy Rice Krispies treats and thought this would be a delicious combo, but of course a quick google search revealed quite a few others who had the same yummy idea long before me.  One of the earliest I can find is from Picky Palate (a site filled with lots of other delicious things too!)

    Thanks for posting this wonderful idea. My nephew has a wheat allergy and rice krispies are a go-to treat. It's easy to find wheat-free "Oreos" and this will offer us some more variety. I'd love to see some more of your Rice Krispie variations.

    Chelsie — March 26, 2012 at 10:41 pm

    Making these again. My husband is in love with these addicting suckers. Only recommendation: use double stuff! The best part is biting into a little piece of filling. Yummmm

    Made these today- super tasty, but mine were a little dry (says my husband). Have you had this happen too? Was I skimpy on the marshmallows maybe? He also wanted "frosting" so maybe trying with double stuff would be good.

    Anne Marie Ainsco — June 28, 2012 at 2:42 pm

    Thanks so much for the recipe Glory. I had the same issue as Anonymous. The next time I’ll be using more than 5 cups of mini marshmallows to make them more gooey and less dry.

    They are still very very tasty though. :)

    It doesn’t say what temperature to cook it at…

    • Glory replied: — February 3rd, 2013 @ 4:42 am

      You don’t need to cook it at all. It will firm up on its own as soon as it’s cool (less than 30 minutes).

    Aysha — July 21, 2013 at 4:34 pm

    Wow these look so tasty, however is there any way of making without marshmallows? Very difficult to find halal ones, but would love to try this out with something else, thanks :)

    Thanks for sharing Glory! After reading your post, my daughter and I (and granddaughter) went for a walk to the local store and bought Oreos and then tonight I made the Oreo Rice Krispy treats. They are DELISH! Thanks so much for sharing! Cristin

      Oh yay, so glad you ladies enjoyed them!!

    Finally made these again today–we like our treats gooey, and thought 5 C of marshmallow wasn’t quite enough. This time I used the recipe as given with one exception… a full 10 oz pkg of mini marshmallows plus another 4-5 large ones. Perfection, at least according to the 1 large and 3 small boys residing in my house! :) Thanks for a great recipe!

    Amy — December 26, 2014 at 10:13 am

    Made these for Christmas dessert tonight and they were a hit! Thank you!

    Only thing is that I would agree with the others who posted that 5 cups of mini marshmallows is definitely not enough. They were simply not gooey enough and wouldn’t stick together well. They ended up quite a bit drier than Rice Krispies treats usually are. Next time I’ll be adding some more marshmallows and a bit more butter, and I think they’ll be perfect! Such a fun and easy treat! :)
