Our Oreo Cake recipe (also known as Cookies & Cream Cake) is a combination of a few tried & true favorites from our Recipes section!
How to Make an OREO CAKE
First, the cake...
Our Classic Chocolate Cake from Scratch is the only chocolate scratch recipe that you'll ever need! It's so moist, chocolatey, and bakes up nice and tall.
If you'd prefer to make a doctored cake mix recipe, you cannot go wrong with this Chocolate Sour Cream Cake! Both of these recipes are crowd pleasers and work well with both buttercream & fondant.
After baking and cooling the three chocolate layers, I piped a dam of buttercream and spread with a thin layer of ganache.
The ganache recipe that I used is a super simple recipe that can be whipped up in no time with the help of a microwave and equal parts chocolate and heavy cream.
You can find all of the details for making an easy ganache here: Ganache Drip Recipe. It makes for a delicious, gorgeous chocolate glaze or drip!
Here I am spreading a thin layer of ganache. I spread my ganache nice and thin so that I would be able to easily spread a layer of Oreo Buttercream on top of it without a lot of sliding. Although I used a thin layer, the ganache delivers an unmistakable layer of richness to an already decadent cake.
Finally, we finished things off with our fabulous Oreo Buttercream Recipe! This is similar to our Classic Vanilla Buttercream recipe, but with finely crushed Oreos! YUM!
As I assembled the cake, I spread Oreo Buttercream filling over the thin layer of ganache between layers.
I then frosted the cake with the Oreo Buttercream and dripped ganache around the top edge using a piping bag with the end snipped away.
The ganache drips most easily when it is just slightly warm. It thickens as it cools and so if it becomes too thick to work with, just pop it in the microwave for 5-10 second increments until it flows easily from the piping bag.
I love ganache drips! So dramatic!
I continued to drizzle the ganache over the top of the Oreo Cake and finished things off with a french tip border (Ateco 863)! Because our Oreos were so finely crushed in a food processor, the frosting was very easy to spread and pipe.
I just love the look and more importantly the flavor of this Oreo Cake recipe!! I think that it will become one of your favorites too!

Oreo Cake- Delicious Scratch Cake Recipe
This Oreo Cake with Ganache and Oreo Buttercream is a favorite at our house! Decadent chocolate layers with an amazing (and easy!) Oreo Buttercream!
For the Cake
- 2 cups (400g) granulated sugar
- 2 ¾ cup (322g) all-purpose flour
- 1 cup (82g) unsweetened cocoa (lightly spoon into cup then sift)
- 2 teaspoons ((10g) baking soda
- ½ teaspoon (2g) baking powder
- ½ teaspoon (2g) salt
- 1 cup (2 sticks) (226g) unsalted butter, softened (do not soften in microwave) I cut the butter into 1 inch pieces onto waxed paper leaving on the countertop for 8 to 10 minutes it will still be quite cool when adding to the dry ingredients. If it becomes too soft, just refrigerate a few minutes
- ¼ cup (54g) vegetable oil
- 4 large eggs at room temperature
- 1 teaspoon (4g) vanilla extract
- 1 cup (220g) milk
- 1 cup (220g) hot coffee, it can be instant or brewed
For the Ganache
- 10 oz. (283g) Chocolate (Semi-sweet or Dark) We used Ghirardelli
- 10 oz. (283g) Heavy Cream
For the Oreo Buttercream Frosting
- 2 sticks (226g) unsalted butter, slightly softened but cool to the touch and holding it's shape
- 7 cups (690-805 grams) powdered sugar (depending on desired consistency. More sugar=more crusting). If you prefer a frosting that crusts less, see our note at the bottom of the recipe.
- 2 tsp. vanilla (8 grams), use clear imitation vanilla if you like a whiter frosting
- ¼ c. (60g) whole milk or more if needed
- ½ teaspoon salt (3g) to cut the sweetness (preferably fine grain or popcorn salt). Adjust to taste.
- Oreos- We used about 10 crushed Oreos for this recipe but use however many you'd like!
For the Chocolate Cake
- Preheat oven to 350 degrees
- Grease and flour THREE 8 inch cake pans
- In a mixing bowl, add the dry ingredients: sugar, flour, cocoa, baking soda, baking powder, and salt. Whisk for 1 minute to blend.
- Add softened butter a few pieces at a time while the mixer is on low speed. Mix until the dry ingredients look like coarse sand and the dry ingredients are moistened. Scrape the bottom and sides of the bowl.
- In a separate bowl whisk the eggs, milk , oil and vanilla until blended.
- Method is important when using the Reverse Creaming Method. With the mixer on low speed, SLOWLY add approximately ½ of the egg mixture to the dry ingredients.
- Increase the speed to medium and mix for 1 ½ minutes at medium speed. Don't mix above medium speed. Scrape the bottom and sides of bowl.
- Add the remaining egg mixture in 2 pourings, beating for 20 seconds after each pour. Scrape the sides and bottom of bowl.
- Slowly add the cup of hot coffee and mix another 30 seconds until blended. The batter will be very runny. Don't worry!
- Pour into 3 prepared 8" pans and bake at 350 degrees for 25 to 30 minutes or until the center of the cake springs back to the touch and a toothpick comes out clean.
- Cool the cakes 10 minutes on a rack and then turn out of the pans.
- *Yields approx 9 cups of batter.

For the Ganache
- Place your chocolate into a microwave safe bowl.
- Pour heavy cream over the chocolate and place in the microwave for 1 minute. (Times may vary, see our note below).
- Remove and stir. Microwave for 30 seconds more and when the chocolate has melted almost completely, allow it to sit for 1 minute more before stirring. Stir until you've reached a silky smooth consistency.
- *Microwave times may vary. If you are making a smaller amount of ganache, you will reduce the microwave time. If your chocolate hasn't melted after the 1 ½ minutes recommended in the instructions, simply microwave in small 10-15 second increments until it has nearly completely melted. Let sit one minute, then stir until smooth.
For the Buttercream
- Cream the (slightly softened) butter until smooth. Blend in the vanilla.
- Add half of the powdered sugar and most of the milk. Beat at medium speed until the powdered sugar is incorporated.
- Add remaining powdered sugar and milk and mix at medium speed another 3 to 4 minutes scraping the sides of the bowl occasionally. I slow down the mixer to very slow. (#2 on the Kitchenaid) for 1 to 2 minutes. This will help eliminate air pockets in the buttercream. The texture will become very smooth.
- Crush the Oreos. We used a food processor for a finer crumb so that the frosting would spread more easily. You can also place them in a Ziplock bag and crush with a rolling pin.
- Fold Oreos into your buttercream.
- This recipe can be doubled or halved.
- Yields approximately 4 ½ cups of frosting. Enough to frost a two layer 8 or 9 inch cake.
- Can be frozen in air tight container for at least three months . Thaw on countertop.
- If your buttercream is too thin, add more sugar. If the consistency is too thick, add a bit more milk.
- **For a Softer Buttercream with a much lighter crust, I cut the amount of sugar from 6 cups to 4 cups, and cut the milk from ¼ cup to 3 tablespoons, and cut the salt to ¼ teaspoon. This lighter consistency of buttercream works great with cupcakes or cakes that don't require the Viva method of smoothing.
Assembly of Oreo Cake
- As you assemble the cake, pipe a dam of buttercream around each layer and fill in with a thin layer of ganache.
- Then, spread Oreo Buttercream over the thin layer of ganache for your filling.
- Frost the cake with Oreo Buttercream, and garnish with a ganache drizzle using a disposable piping bag with the tip snipped away.
- I drizzled a crisscross design over the top and piped a ring of Oreo Buttercream stars around the top using an Ateco 863.

Hi Manal, We do not have a video for this recipe but we do have a video on How to Make a Cake from Start to Finish. Click on the link below if you would like to watch it.
Hi. Thanks for the recipe. If i will be using instant coffee, do I need to add water to the coffee powder? What is the ratio?
Hi Jaz, for the chocolate layers, you will pour 1 cup of hot coffee into the batter. You can just go by the instructions on your instant coffee container as to approx how much to add to the cup of hot water.
Hi, do I need to remove the cream from the cookies before crushing?
I used a blender to finely crush the Oreos for the buttercream and I didn't remove the cream- no issues! ;0)
This cake is absolutely delicious!! A little extra work, but oh my does it pay back with velvetty rich layers & oreo buttercream that will have them asking for seconds! The coffee & the reverse mixing method, just takes this cake over the top.
Hi Debbie, We are so happy you enjoyed the cake. Thanks so much for posting your review of the recipe.
