How to Make Oreo Rice Krispie Treats

Prepare a 9-inch square pan (for thicker rice krispie treats) or a 9×13-inch pan (for thinner rice krispie treats) by coating generously with butter; set aside. In a large mixing bowl, combine the Rice Krispies, chopped Oreos, and 1 cup of the marshmallows.

These rice krispie treats will be just the right crunchy, dense, and slightly sticky texture. The Oreos add a delicious chocolate flavor.

How to Store the Leftovers

Keep the rice krispie treats in an airtight food storage container or a zip-top bag. They will stay fresh at room temperature for up to a week. Refrigerating the krispie treats will make them very hard, so if you need to keep them in the refrigerator, be sure to let them come to room temperature again before serving.

    Such a yummy quick treat! A secret I learned awhile ago is to let your butter just get a tiny bit browned before adding the marshmallows. Takes up a notch. Also added a 1/4 tsp vanilla. Thanks for the great recipe!

    This is a great recipe!  I added just a teaspoon of vanilla extract and that made it even better!

    Easy and delicious. I had to hurry and make this or the marshmallows and cookies would have disappeared. We used non dairy butter and it came out great. We couldn’t wait till they set and started eating them in scoops right away. Even the picky Mr liked them.
