How To Make Oreo Marshmallows
Just follow these simple steps to make a quick dessert everyone will love!
Step 1 – Chop Up Oreo Cookies
Begin by chopping the Oreo cookies into chunks.
Step 2 – Prepare Gelatin
In a small bowl, add cold water and gelatin. Stir gently and set to the side.
Step 3 – Cook Syrup
Add corn syrup, salt, sugar, and water into a large saucepan. Cook over medium heat.
Cook the mixture until the sugar is dissolved stirring continuously.
Once the sugar is dissolved, turn the heat to medium-high. Bring the sugar mixture to a boil. The mixture should reach 240°F or forms a soft ball.
Step 4 – Add Vanilla
Add vanilla extract to the gelatin mixture.
Step 5 – Combine Syrup And Gelatin
Swiftly add the syrup mixture to the gelatin in a large mixing bowl.
Whisk on high heat until soft peaks begin to form and start to look like marshmallow cream.
Step 6 – Combine Powdered Sugar And Cornstarch
In a separate bowl, mix the powdered sugar and cornstarch.
Step 7 – Prepare Dish
Prepare a rectangular or square baking dish with cooking spray. Then dust the dish well with the powdered sugar and cornstarch.
Step 8 – Add Marshmallow Mixture To Dish
Put the marshmallow mixture into the backing dish and spread out evenly.
Step 9 – Top With Chopped Oreos
Completely cover the top of the marshmallow cream mixture with the Oreo cookie crumbs.
Step 10 – Let Oreo Marshmallow Cream Set
Allow the cookie and marshmallow cream to set up overnight.
Step 11 – Cut Oreo Cookie Marshmallows Into Squares
Remove the marshmallow and place on a dusted area covered with cornstarch and confectioners’ sugar.
Pro Tip: I often like to sheet a piece of parchment paper down and dust that before putting the huge marshmallow down on top – easy cleanup!
Cut the cookies and cream marshmallows into small pieces. Dust the sides of the marshmallows with the powdered sugar and cornstarch mixture.
Enjoy your cookies and cream marshmallows!
Cookies and Cream Marshmallows Recipe Notes And Tips
This simple recipe is such an easy dessert to make! Here are some tips so that your marshmallow goodness turns out perfectly every time!
- TIP: Mix the powdered sugar and cornstarch before starting the marshmallow cream. This way you will not have to let the marshmallow cream sit and you can keep the process moving.
- Cooking spray will be helpful when preparing this recipe. Use it in the baking dish and also on the knife when cutting the Oreo marshmallows into squares.
- Place cookies in a plastic storage bag and smash cookies with a rolling pin or your hands until you reach the desired size of cookie pieces.
- A candy thermometer is SUPER helpful for making this recipe!
- Use a pizza cutter sprayed with cooking spray can be a great way to cut the marshmallows.
- Cutting Tip: Cutting cookies and cream marshmallows into pieces before they have cooled and set completely will give you a soft and gooey marshmallow! However, waiting until they are set completely will give you a firmer product that’s perfect for gifting!
How To Serve Oreo Marshmallows
- They are delicious in a cup of homemade hot chocolate
- Make some cookies and cream Rice Krispie treats
- No-bake Oreo marshmallow bars are a great (and affordable!) item to make for holiday bake sales!
- Make marshmallow skewers (or kabobs)
- Dip in melted chocolate for an unforgettable treat or DIY gift
- Wrap up some Oreo marshmallows (and some homemade hot chocolate) as DIY gifts to friends and family, along with some homemade hot cocoa mix
Variations Of Cookies and Cream Marshmallows To Try
- There are many flavors of Oreos such as peanut butter, toffee crunch, chocolate creme, and mint chocolate that would work fabulously for this recipe. Of course, you can’t go wrong with using double-stuffed Oreo cookies!
- Use the Oreos with the colored icing for holiday treats such as the Oreos with red icing for Christmas, orange icing for Halloween, and the green mint chocolate Oreos for St. Patrick’s Day. 😜
Make Oreo Marshmallows Gluten-Free
Except for the Oreos, all the ingredients in this tasty treat are naturally gluten-free. To make these marshmallows gluten-free, all you have to do is replace the regular Oreos with gluten-free Oreos.
Oreo Marshmallow Storage
You can make these Oreo marshmallows ahead of time! They will keep for up to 2 – 3 weeks if stored in an airtight container (or a large Ziploc bag) at room temperature.
I don’t recommend freezing cookies and cream marshmallows. Their texture will change and they’ll get sticky when they thaw out. It’s really just not good. However, this recipe can be made quickly so they’re easy to whip up if you need to!
