This homemade Oreo Cookie Cake has two layers a rich, moist chocolate cake filled and covered in a light Oreo whipped cream frosting! It makes a great birthday cake for any cookies and cream lovers.
If you’re a fan of homemade cake recipes…well then, you’re going to want to listen up. Because this Oreo Cake? …well, it’s heaven. If you’re a fan of all things cookies n cream like I am, you will adore this! It’s one of my favorite ice cream flavors (alongside this homemade white chocolate oreo ice cream) and this cake tastes JUST like a giant Oreo and cookies and cream ice cream had a baby. What more could you want?
This cake, my peanut butter mousse pie, and a few other treats were all made in the same 4 day period.
Every night, after we ate dinner, my dad, my best friend Paige, and I would be sitting on the couch, watching TV, or a movie, or doing whatever. At some point, one of us would walk over and bring out the cake and the pie. The three of us would stand around the counter, shaving off small slices of each. And more small slices, and more, until we were all so full of chocolate, peanut butter, and Oreo cake.
The cake and the pie would be placed back into the fridge, smaller than when they were taken out, until the next sugar craving hit. It was troubling when they finally disappeared, and ever since, I’ve been desperately wanting a spare hour or two so I can make this cookies and cream cake again.
If someone told me to choose between the two, I don’t know if I could. Each was amazing in it’s own right. The peanut butter mousse pie was rich, and you can read more about it in its own post. But let’s get into the cake:
How do you make Oreo frosting?
The chocolate cake layers themselves are light and fluffy, and a pretty classic chocolate cake. The frosting is where things really get super deliciously exciting. It’s barely even frosting in the traditional sense — it’s not made with butter or loaded with absurd amounts of powdered sugar.
Instead, we make a big batch of freshly whipped cream with loads of crushed Oreos mixed in, sweetened with just a touch of sugar and flavored with a little bit of vanilla. Once the frosting is fluffy and gorgeous, you’re going to pile it high between and on top of the layers. I like having each layer of frosting be as thick as each layer of cake. It’s that good. And because the frosting is so light and fluffy, it makes sure that the cake isn’t overwhelmingly chocolatey or sweet.
Can I use a different flavor of Oreos? Of course! Now that Oreo has so many fun flavors, you can use any of them to make a twist on this oreo cake. Peppermint would be so great for the holidays! They’re always coming out with new flavors too, so have fun with it.
It was just…delicious. The only downside of this cake? It was so light and airy, I wouldn’t feel full, soooo…I would just keep on eating it. A delicious problem to have!
This oreo cake is easily one of my favorites (especially because I’m not a huge fan of traditional super-sweet frostings) that I’ve ever tasted, none the less made. I hope you enjoy it as much as I did! Happy baking :)

Oreo Cake
Ingredients
For the cake
- 1½ cups 6.25 oz all-purpose flour
- 1 cup 7 oz sugar
- 1 cup cold water
- ⅔ cup vegetable oil
- ¼ cup .75 oz unsweetened cocoa powder
- 1 teaspoon baking soda
- 1 teaspoon white vinegar
- ½ teaspoon salt
- 1 teaspoon vanilla
For the Oreo whipped cream
- 50 Oreo cookies
- 4½ cups heavy cream
- 2 tablespoons granulated sugar
- 1 tablespoon pure vanilla extract
Instructions
For the cake
- Preheat oven to 350ºF. In large mixing bowl, combine all of the cake ingredients. In a stand mixer or using a hand mixer, beat on medium speed until everything is well combined and a smooth batter forms. Pour batter into a greased 9-inch baking pan (or divide between two 9″ pans, if you don’t want to split the cake later).
- Bake for 20 to 25 minutes (12 to 15 minutes if you’re dividing between the 2 pans) or until a toothpick inserted into the cakecomes out clean. Cool completely, and place in the freezer for ½ hour before assembling.
For the Oreo whipped cream
- Cut 6 Oreo cookies in half and set them aside – these will be used as the garnish. Chop remaining cookies into 1/4-inch pieces and set aside.
- Make the Oreo whipped cream in 2 batches. In the bowl of a standing mixer fitted with the whip attachment, whip 2 cups of heavy cream on medium-high speed to a soft peak, and then spoon the cream into a large bowl. In the same mixer bowl, whip the remaining 2½ cups of cream, along with the sugar and vanilla, to a soft peak. Fold into the already whipped cream.
- Place about 1 cup of whipped cream in a different bowl and refrigerate until ready to decorate the cake. Fold crushed Oreos into the remaining whipped cream.
To assemble the cake
- Remove the cake from the freezer. Slice the layer in half horizontally to create 2 layers, I like using a cake leveling tool to help make two even layers. Place the bottom layer on a serving plate. Spread about 1/3 of Oreo whipped cream onto the bottom layer of the cake. Top with the second cake layer and use the remaining Oreo whipped cream to frost the top and sides of the cake. Chill in the refrigerator for about 2 hours to allow cookies to soften.
- Place reserved whipped cream in a pastry bag fitted with a star tip, re-whisking the cream if necessary. Pipe 12 whipped cream rosettes around the perimeter of the cake and garnish with reserved Oreo cookie halves. Serve immediately, or store in the refrigerator until ready to serve.

Oh my this looks decadent! My hubby would lOVE this!
Hey Rachel, I have just made this cake and what surprised me was how incredibly MOIST the cake was, how easy this was to make and how absolutely incredible the Oreo whipped cream topping was. I made this cake for one of the children’s birthdays and while we haven’t had it yet, they LOVE store bought Oreo cakes and from the wee sampling I did this one is FANTASTIC! Thank you so much for sharing this. Can’t wait until tonight. They’re going to think I am the bomb for making this. :o)
Hi Jenna, I hope your boys like the cake!! It’s one of my favorites as well. So glad you liked the recipe :) thanks for stopping by the blog!
Looks delicious! But could I substitute Cool Whip or canned whippped cream for the hand-whipped cream?
I haven’t tried it, but I would definitely go with Cool Whip over canned whipped cream if you were to try it. I’m sure it would still be great!
Hello this cake absolutely looks delicious…….I tried it today and I did it twice cause the first time it was nasty and I thought it was cause I put to,any baking soda in it so I made it again but it turned out tasting the same!!!!!
So now my question is this I used olive oil non stick spray do you think that might have been the reason it tasted weird?????
Hi Kasheema, the olive oil non stick spray could definitely give the cake a weird, off-tasting flavor. Try using an unflavored nonstick spray, or just use butter and that flavor will go away.
Hi Rachel, Thanks for sharing this wonderful recipe. I tried it and it turned out to be the most amazing cake I’ve ever made. My son and I are big fans of Oreo. This wont’ be the last time I’ve made it. :)
Thank you, thank you…
I’ve made a post here: http://mimismommy.wordpress.com/2014/02/15/oreo-cake/
So glad that you and your sons enjoyed it!! Thanks for trying it!
Hello there, I have a friend who has set up a home baking business (http://firjun.wix.com/batter-mischiefs#!cakes/cz0j). She has just set up her website and I thought that some of her pictures might not belong to her. I was just surfing and I found your website. Lo & behold the picture of your Oreo cake came up! She might have taken it straight from your website. I am not sure how you feel about others using your pictures but I think it’s not right. I also feel it’s wrong of my friend to put pictures of cakes that she didn’t bake and passed them as her own.
Hi Eva, thank you so much for letting me know. I really appreciate it, and will deal with it accordingly.
This cake looks really nice. Love the idea of oreos in the frosting. My daughter will love this
This cake is gorgeous! I love how you placed the Oreos on the top. Looks perfect.
that is one helluva cake! Looks amazing. ps – just started following you on twitter so I can keep up with your fab creations.
I’m a little confused on the frosting. What did you do to make the rosettes on top chocolate instead of matching the rest of the frosting?
Hi Claire! It is actually the same frosting, but the Oreo chunks wouldn’t fit through my piping tip, so I threw the frosting in a food processor for a few seconds to break up the Oreo chunks more, which is why the frosting looks darker! Hope this answers your question.
