How to make OREO Rice Krispie Treats
Start by melting the butter, marshmallows, and white chocolate chips either on the stove or in the microwave then toss in the OREO Cookie pieces and Rice Krispies Cereal.
Stove Top Method
- Grease an 8-inch square pan with either butter or non-stick cooking spray.
- Pour 4 tablespoons of European Salted Butter*, 1/3 cup white chocolate chips, and 10 ounces mini or regular sized marshmallows into a large saucepan.
- Set the pan over low heat and allow to melt, stirring often, until about 75% of the marshmallows are melted.
- Remove the pan from the heat and continue to stir until all the marshmallows and white chocolate melt.
- Stir in 4 cups of Rice Krispies Cereal and 14 OREO Cookies, broken into pieces.
- Gently press the cereal treats into the prepared pan.
- Break up 2 more OREO Cookies and add on top of the treats in spots where there are no cookies.
- Let the treats cool for at least 30 minutes before cutting into 16 squares.
- Combine 4 tablespoons of European Salted Butter*, 1/3 cup white chocolate chips, and 10 ounces mini or regular sized marshmallows.
- Heat on high power for 1 minute then remove and stir until the marshmallows and white chocolate chips begin to melt.
- Heat for additional 15 seconds then let the bowl sit in the microwave for a minute before removing.
- Stir until the marshmallows and white chocolate melt and blend together with the butter.
- Keep stirring! The heat from the melted marshmallows will continue to melt the bits of marshmallows that remain.
- Of course every microwave heats differently so at this point if your marshmallows are still not fully melted you can heat for 15 second bursts of high power, stirring after each until fully melted.
- Just be careful to not overheat the marshmallows. If they get too hot they will will become more like hard candy and will create hard rice krispie treats.
- Stir in 4 cups of Kellogg’s Rice Krispies Cereal and 14 OREO Cookies that are broken into small pieces.
- Gently press the cereal treats into a prepared pan.
- Immediately break up 2 more OREO Cookies and press the pieces on top of the cereal treats, adding them where there are no cookie chunks.
- Set aside to cool for at least 30 minutes before cutting into 16 squares.
*What’s the best butter to use?
- When creating our BEST Rice Krispie Treats recipe we had 20 people taste test many different brands of butter in our recipe and found everyone unanimously agreed that European salted butter makes the most flavorful rice crispy treats.
- We choose to use either President Salted Butter or Kroger Private Selection French Cream Butter but Land O Lakes new European Butter tastes really nice in these cereal treats too.
- Does salted butter really matter? Yes! It really does make better tasting treats.
How to prepare my pan?
- I prefer to use a non-stick pan to make my cereal treats because even as gooey as they can be they won’t stick much to a non-stick pan.
- To ensure the treats won’t stick I like to butter the pan first.
- You can also spray the pan with non-stick cooking spray, if you prefer.
- If you use a glass pan it will be essential that you butter or spray the pan.
Can I use a 9″X13″ inch pan?
- Yes, but you will need adjust the quantities. See the recipe below.
How to make a larger batch of these OREO Cookie Cereal Treats?
- Melt 6 tablespoons European Salted Butter, 16 ounces marshmallows, and 1/2 cup white chocolate chips.
- Stir in 6 cups of Rice Krispies Cereal and 18 OREO Cookies, broken into small pieces.
- Spread into a 9 inch by 13 inch, greased, pan,
- Top with 3 or 4 more OREO Cookies, broken into pieces.
- Cool for at least 30 minutes before cutting into 24 pieces.
What type of white chocolate to use?
- I added 1/3rd cup of Nestle Premier White Morsels. I really like the nice vanilla flavor the chips add to these cookies and cream style cereal treats.
- You can use any white chocolate that you enjoy eating, just be sure to chop it finely, if using bars or blocks of white chocolate.
