How to Make Oreo Cake
Although this Oreo cake looks SPECTACULAR, I promise it isn’t that difficult to make 🙂
As always, the full ingredients list and written instructions are on the recipe card at the end of the post!
Begin by preheating your oven to 160 °C (320°F) with the fan on (see note 4 on recipe card below if you don’t have a fan function) and grease and/or line two 8 inch cake tins (I use my homemade cake release).
Next you want to roughly chop 14 Oreos to mix into the cake batter at the end. You don’t want them to be too big or too small (you want little chucks). Set aside for now.
In a bowl, sift together your flour, cornflour, baking soda, baking powder and salt. Using a whisk or fork, mix until well combined. Set aside.
In another bowl, add in your butter, vegetable oil and sugar. Using an electric mixer (hand or stand mixer are both fine – see note 2 on recipe card below), cream together for 2 minutes until light and creamy.
Add in eggs one by one, mixing well in between each addition (about 10-15 seconds between eggs).
Add in your vanilla, vinegar and half a cup of the buttermilk (112g), and mix until well combined. Now set your mixer aside as the remainder of the batter will be finished by hand.
Next add in half of your premixed dry ingredients to your wet mixture, and gently fold it in with a spatula until just combined. Then add in the remaining 1 cup of buttermilk (225g) , and fold it in until just combined. Lastly, add in the remaining dry ingredients and gently fold it into the mixture until just combined. Do not overmix (see note 3).
Finish off by adding in the roughly chopped Oreos from earlier and gently mix with the spatula until just combined. Do not overmix.
Distribute the batter evenly into the two 8 inch cake tins, and bake for 33 minutes or until a toothpick comes out clean.
Once baked, allow the cake layers to cool in the cake tins for about 15-20 minutes, and then turn them out onto a wire rack to completely cool.
How to make Oreo buttercream
In a food processor (or blender), place in the 14 Oreos and blend until they resemble fine crumbs. Set aside for now.
In the bowl of a stand mixer, add in the icing sugar, butter, vanilla and milk.
Using the paddle attachment, mix on the lowest speed until the ingredients are combined (about a minute), and then turn up the speed to a medium high and mix for a full 10 minutes. Scrape the bowl down half way through.
Finish off by adding in the crumbed Oreos from earlier and mix on a medium speed until well combined.
How to assemble/decorate your Oreo cake
Now you can totally exercise your creative freedom here, but here is how I did mine 🙂
OPTIONAL: Trim off the caramelised edges on the top, bottom and sides of the cake layers with a serrated knife. This is purely for aesthetic purposes so you can skip this step if you prefer. Level the tops if necessary.
Place the first cake layer onto your cake stand and place a generous amount of Oreo buttercream on top and smooth it out with an offset spatula or knife.
Next crush three Oreos in the palms of your hands and sprinkle them on top of the buttercream. These chunks of Oreos will add great texture and crunch to your cake.
Place your next cake layer on top and cover the top and sides with buttercream, leaving a little left for piping on the top. I like to use a cake scraper to smooth out the sides.
Place the remaining buttercream in a piping bag with a 1M piping tip on it, and pipe little swirls around the top edges of the cake.
In a food processer, blend another 4 Oreos until they resemble fine crumbs. Using your hands, gently push the Oreo crumbs up against the sides of the cake until about half way up. They should stick to the buttercream. Remove any excess Oreo crumbs from the bottom.
Finish off by adding individual Oreos on the top of each swirl that was piped on the top of the cake. Enjoy!
Soft Oreo Cake (Cookies & Cream)
Print Pin VideoIMPORTANT: For accuracy, I would recommend using the gram measurements provided, as those are the exact quantities I use. Cup measurements are given as estimates (based on US cup measurements) to make it easier for those who do not have a scale.
Ingredients
Oreo Cake
- 14 Oreos - roughly chopped
- 2⅓ cups (300 g) flour - regular all purpose (see note 1 if you want to use cake flour)
- ¼ cup (25 g) cornstarch
- ½ tsp baking soda
- 1 tsp baking powder
- ½ tsp salt - omit if using salted butter
- ½ cup (113 g) unsalted butter - room temperature
- ½ cup (105 g) unflavoured vegetable oil - I use canola
- 1⅔ cups (332 g) white granulated sugar
- 3 large eggs - room temperature
- 1¼ tbsp vanilla essence/extract
- 1 tsp white vinegar
- 1½ cups (337 g) buttermilk - room temperature, see note 5 if using a homemade buttermilk substitute
Oreo Buttercream Frosting
- 14 Oreos - blended to fine crumbs
- 1½ cups (340 g) unsalted butter - room temperature
- 2¾ cups (350 g) icing sugar - also known as powdered sugar/confectioners sugar
- 1½ tsp vanilla essence/extract
- 1½ tbsp milk - heavy or whipping cream okay too
Extra for Decorating (optional)
- 3 Oreos (recommended) - to go it between the cake layers to add extra crunch/texture
- 4 Oreos (optional) - to decorate the sides of the cake (blended into fine crumbs)
- 10-12 Oreos (optional) - to put on the top of the cake
Instructions
- IMPORTANT: For this recipe I would highly recommend using gram measurements, especially for the flour for accurate results. It has a high fat/liquid ratio so slight adjustments to the quantities can throw off the balance of the cake 🙂

Looks delicious. A must try. Especially the decorations. What is the purpose of the vinegar? Thanks. Love your channel. New subscriber.😃
Hi Michelle! Thanks so much 🙂 and the vinegar helps to break down the protein in the flour resulting in a more tender cake :). So glad to hear you’re enjoying the channel and thanks so much for subscribing 😀
Oreo cake looks delicious but if u using a regular oven I know the notes states bake at 347 degrees which is odd because is that the same as 350 degrees and would the baking time be the same ?????
Hi Shavon! Yes 350F will be fine 🙂 and baking time should be the same 🙂
When I finish my cake by hand mixing, my cake doesn’t rise like it does when I use my mixer.
What am I doing wrong?
I don’t have a convection oven, and I set my oven temperature to 350 as I would any cake.
Hi Valerie! It could be that not enough air was whipped in during the creaming process? If you prefer your stand mixer then you can also use it for this recipe, just make sure it’s on the lowest speed when adding in the dry ingredients at the end, and that you’re using the paddle attachment 🙂
Awesome Maryam! This is why I follow you for all your recipes! Thank you.!
