The Ingredients

Here’s what you’ll need to make the Oreo Rice Krispie Treats (the exact measurements and full recipe instructions are below in the printable recipe card):

  • Rice Krispies – I used a store brand “crispy rice” cereal and it was perfect. Use any brand you like.
  • Oreo cookies – I used the regular Oreos, but the double stuffed could also work in this recipe.
  • Butter
  • Mini marshmallows – Please know that you may need 2 bags of marshmallows to have enough for this recipe.
  • Salt

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.

Additions

In addition to the Oreos cookies, here are some other mix-in ideas:

  • M&M’S – mini or regular
  • Reese’s Pieces
  • Chocolate chips – mini or regular
  • Golden Oreos
  • Dried cranberries
  • Peanut butter chips
  • White chocolate chips
  • Colorful sprinkles

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.

    I have been making these for years now and they are always a huge hit. To change them up I just made them with the new Reese’s Oreos and they are amazing!
