These Oreo Rice Krispie Treats elevate the classic childhood favorite with the irresistible addition of crushed Oreo cookies folded into a perfectly gooey marshmallow mixture. Extra thick, extra marshmallowy, and packed with cookies and cream flavor.

The first time I made these for my kids' playdate, they vanished within minutes! My son declared them 'the best thing you've ever made,' which is high praise from a picky eight-year-old.

I created this recipe when my kids wanted both Rice Krispie treats and Oreos. The happy accident has become our most requested treat - my daughter asks for these instead of birthday cake!

These Oreo Rice Krispie Treats represent what I love about simple desserts - a small twist on a classic creates something special while maintaining comforting familiarity.

Frequently Asked Questions

→ Can I use regular-sized marshmallows instead of mini ones?
Yes, you can substitute regular marshmallows for mini ones. As a general rule, 1 cup of mini marshmallows equals about 10 regular-sized marshmallows. They might take a bit longer to melt, but the result will be the same. Just make sure to keep stirring until they're completely melted.
→ Why add salt to sweet Rice Krispie treats?
Salt enhances and balances the sweetness in desserts. In these Oreo Krispies, the small amount of salt helps to amplify the chocolate flavor from the Oreos and creates a more complex taste experience. It's a small addition that makes a big difference in the final flavor.
→ My treats turned out too hard. What did I do wrong?
Hard Rice Krispie treats usually happen when they're pressed too firmly into the pan or when the mixture was cooked at too high a temperature. Use a gentle touch when spreading the mixture into the pan, and be careful not to overheat the marshmallows. Also, adding too much butter can make them hard when cooled.
→ Can I use other types of cookies instead of Oreos?
Absolutely! This recipe works well with many different cookies. Try using chocolate chip cookies, Nutter Butters for a peanut butter version, Biscoff cookies for a caramel-spice flavor, or even Girl Scout cookies like Thin Mints or Samoas for a unique twist.
→ How do I prevent my spatula from sticking to the marshmallow mixture?
Lightly coat your spatula with cooking spray or a small amount of butter before using it to stir the marshmallow mixture or press the treats into the pan. This creates a barrier that prevents sticking, making the whole process much easier and less messy.

Ingredients

→ Main Ingredients

01 5 tbsp butter
02 9 cups mini marshmallows, divided
03 5 cups Krispie cereal
04 16 Oreo cookies, crushed
05 1/2 tsp salt

Instructions

Step 01

In a large bowl, mix together the Krispie cereal, crushed Oreo cookies and one cup of mini marshmallows.

Step 02

In a large saucepan over medium heat, melt the butter completely.

Step 03

Add the remaining 8 cups of mini marshmallows and salt to the melted butter. Stir continuously over medium heat until the marshmallows are completely melted and incorporated with the butter, creating a smooth mixture.

Step 04

Pour the melted butter and marshmallow mixture over the Krispie cereal mixture. Using a rubber spatula, gently fold everything together until the cereal and Oreos are evenly coated with the marshmallow mixture.

Step 05

Transfer the Oreo Krispie mixture into a 9-inch square pan. Using the spatula, press gently to flatten the top and create an even surface. Don't press too hard or the treats will become dense.

Step 06

Allow the Oreo Krispies to cool in the pan for about 30 minutes before slicing into squares and serving.

Notes

  1. For extra Oreo flavor, you can add a few additional crushed cookies on top of the treats right after pressing them into the pan.
  2. Store in an airtight container at room temperature for up to 3 days for best freshness.
  3. Line your pan with parchment paper with overhanging edges for easier removal and cutting.
  4. If your treats are difficult to cut cleanly, lightly coat your knife with cooking spray.
