Ingredients for Oreo Rice Krispie Treats
Rice Krispie Cereal – Rice Krispie cereal is the perfect blank canvas for to cover in marshmallows and Oreo cookies. Any brand of crispy rice cereal will work in this recipe.
Marshmallows – Miniature marshmallows melt quickly into a sweet, sticky mixture that will hold the Rice Krispie treats together.
Oreo Cookies – Chocolatey, crunchy Oreo cookies filled with smooth vanilla creme add texture and classic cookies and cream flavor to the squares. This recipe calls for regular Oreos to crush up into the Rice Krispie mixture and mini Oreos to garnish the top.
White Chocolate Chips – White chocolate chips add a creamy, sweet flavor to the Rice Krispie treats and complement the crisp rice cereal and gooey marshmallows.
Milk Chocolate Chips – Milk chocolate chips add contrast to the Rice Krispie treat, as well as adding even more delectable chocolate flavor to the dessert.
Butter – One of the three ingredients necessary for a classic Rice Krispie treat. The butter helps the marshmallow stay stretchy and gooey, as well as adding a delicious buttery flavor to the final dessert.
Rice Krispies – If you don’t have Rice Krispie cereal, another rice cereal like Chex can be used as a substitute.
Marshmallows – This recipe can be made using one 10oz bag of regular-sized marshmallows rather than 4 cups of miniature marshmallows.
Butter – This recipe can be made with margarine or another non-dairy butter substitute.
How to Make Oreo Rice Krispie Treats
Step 1: Make the marshmallow mixture.
In a large pot, melt together the butter and marshmallows over low heat. Then, add the white chocolate chips and stir to fully melt. Remove the pot from the heat.
Step 2: Stir in the cereal and cookies.
Stir in the rice cereal and crushed Oreos.
Step 3: Shape and cool the treats.
Pour the Rice Krispie mixture into a greased pan, using your hands or a spatula to press them flat. Drizzle the top with melted milk and white chocolate, and decorate as you wish with mini Oreos. Allow the treats to fully cool in the refrigerator or freezer for just a few minutes to allow the marshmallows and chocolate to firm up. Slice into squares and enjoy a bite of heaven!
Oreo Rice Krispie Treat Recipe Pro-Tips
- When you crush up your Oreos into pieces, think about how big you want to make them. If you crush them too much, they’ll be like Oreo crumbs instead of pieces.
- To crush the Oreos, place them into a resealable zip-top bag and use a heavy object like a pint glass or rolling pin to get varying sizes of Oreo pieces.
- Measure your butter (and all your ingredients) carefully! This is so important with Rice Krispie squares because if your butter to cereal ratio is off, you can end up with dry treats, or treats that won’t harden enough and stay slippery and buttery.
- To make clean-up easier, use a non-stick or Teflon pot.
- To melt the chocolate, place it into a microwave-safe bowl and microwave in 15 to 30-second increments, stirring in between. When there are just a few remaining pieces of chocolate left, stir until it melts the rest of the way. This prevents the chocolate from scorching and will result in perfectly drizzleable chocolate to top your Rice Krispie treats.
- Uh oh! Are your treats too hard? You can fix it by placing one or two in the microwave for about 7-10 seconds just before you eat it! But if you have an entire batch that’s hard, you can try placing them in a zip-top bag with a piece of fresh bread, and leaving them overnight. The Oreo Rice Krispie squares should soak up some of the moisture from the bread and become softer.
- Is your mixture sticking to your hands? If your Rice Krispies and marshmallow are sticking to your hands, just dip them in a bit of cold water. This will help keep the marshmallow from sticking. This also works for your spatula, too!
Looking for Rice Krispie treat recipe variations? Here are some other Rice Krispie flavor ideas.
- Try using a different flavor of rice cereal, like chocolate, fruity, or peanut butter, for a completely new taste.
- Use packaged chocolate chip cookies or another cookie of your choice to make a chocolate chip version of this recipe.
- There are about a dozen different flavors of Oreos in the grocery store these days. Give a flavor like mint, chocolate hazelnut, or s’mores for a fun variation on the classic cookies and cream!
These cookies and cream Rice Krispie treats are the perfect dessert to make ahead of time to bring along to a potluck, because everyone loves them! Use them at a birthday party instead of a birthday cake, or take any event that just needs a sweet treat. They’re also great as an after-school snack!
How to Store
Room Temperature – Keep these treats in an airtight container at room temperature for up to five days. Rice Krispies don’t need to go in the fridge to be stored.
Freezer – Make sure your Oreo Rice Krispie squares are fully cooled, then cut them into squares. Wrap your squares tightly in wax paper, then place them in an airtight container or large zip-top bag. You can freeze them for up to 3 months. If you want to freeze the square in large pieces, you can do that too.
Oreo Rice Krispie treats can be made up to three days in advance. It’s important to keep them in an airtight container; otherwise, they will harden too much and not be very tasty.
This recipe uses melted chocolate to drizzle over the Rice Krispie treats. Some other ideas could be melted peanut butter or butterscotch chips, or even spreading homemade buttercream icing over the top and decorating with sprinkles. The possibilities are truly endless!
Rice Krispie squares harden up pretty fast! They should be good to go within an hour in the fridge, or a few hours on the counter. You can also pop them into the freezer for an extra quick set if you need. If you just can’t wait, try to let them set for 20-30 minutes, then you can cut them, but they’ll still be a bit ooey gooey.
