From this crack pie to these crack cookies, it’s all about addiction these days. I made these for a bake sale being held in conjunction with a fundraising car wash, and they were a hit! My family was sorry to see them head out of the house on a platter, intended for OTHER PEOPLE. Oh, the horror of it all! Must. Make. More.

Recipe: Cookies and Cream Rice Krispies Treats

Summary: For those who love Rice Krispies Treats and Oreo Cookies (that includes 100% of the population), these Cookies and Cream Rice Krispies Treats are completely addicting. (In the best way.) 


  • Cookies and Cream Rice Krispies Treats6 tablespoons butter (plus a bit more for greasing the pan)
  • 1 (10.5-ounce) bag mini marshmallows
  • 6 cups Rice Krispies cereal
  • 2 cups coarsely chopped Oreos (chop with a knife)
  • 3/4 cup finely chopped Oreos (about 8 or 9, broken and whirled in a blender)
  • 1 cup white chocolate chips


  1. Grease the inside of a 13- by 9-inch baking dish with butter. Set aside.
  2. In a large, heavy pot, melt butter over medium-low heat. It will first melt, then foam, then become clear golden and finally start to turn brown and smell nutty. As this transformation occurs, stir frequently, scraping up any tiny brown bits from the pot bottom. Don’t walk away from the pot because once the butter begins to take on color, it browns quickly. Once it browns, it may burn in as little as a minute, so watch carefully.
  3. As soon as the butter becomes nutty brown, add the marshmallows and turn the heat down to lowest. Stir and melt the marshmallows, which will become smooth and glossy. Turn heat off and working quickly but gently, stir in cereal and chopped cookies. Immediately scrape sticky contents out into prepared pan. Use your greased hand, an offset spatula or the back of a spoon to gently press the mixture evenly into the pan.
  4. Melt the chips in a glass bowl in the microwave oven, stir until smooth, and frost the top of the cookies. Sprinkle on the Oreo dust and press it lightly to adhere it to the white chocolate.
  5. Allow to cool on the counter for 5 minutes, then transfer to the refrigerator and chill it for 20-30 minutes. This will allow for cleaner cutting.
  6. Cut into 24 squares (4 rows vertically and 6 rows horizontally).

Quick notes

This recipe has a lot of parents! Apparently it has taken a village to get this one raised. I adapted it after seeing it at Foodbeast, who got it from Baking Junkie, who adapted it from Annie’s Eats, who adapted it from Cast Sugar , who said she adapted it from several recipes.

My son is crazy for Oreos & Rice Krispie Treats…he would love these! Will be trying them out using Marshmallow Fluff to avoid the gelatin.

These look so good – – I’ve never thought of adding crushed cookies into the Rice Krispie Treats, but it sounds wonderfully sinful!


Dorothy October 7, 2011 at 4:20 pm

These must be made, oh yes indeed.

Hi Dorothy,

Guess what? You won a copy of Teen Cuisine! Pls. email me your name and mailing address. And a few of those Cookies and Cream Rice Krispie Treats. I’m kidding about the Treats, but not about the book!



Dorothy September 28, 2011 at 9:07 am

Yippee! What fun it will be to look through this with my 14-year-old daughter!
Thank you.


Connie Kaiser September 26, 2011 at 12:04 pm

WOW! Must make these – thanks!!!!

I grew up as a kid eating rice krispies. I’ll always remember the fond memories of going to school and enjoying my packed store bought version of marshmallow rice kripies bars. This recipe definitely will raise the bar for an already great treat to begin with. Thanks for sharing this post 🙂


Dorothy September 26, 2011 at 10:51 am

Thanks! I ALWAYS loved Rice Krispies Treats, too. Even the store-bought version.
