Why we Love It

There are so many reasons to love this Oreo Cake recipe!

How to Make an OREO CAKE

Our Oreo Cake layers are based on our Classic Chocolate Cake from Scratch . They are rich, chocolatey, and moist! 

After baking and cooling the three chocolate layers, I piped a dam of buttercream and spread with a thin layer of chocolate ganache.

The ganache recipe that I used is so easy to make in the microwave, with equal parts chocolate and heavy cream.

For each chocolate layer, 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.

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.

Next, I 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.

The ganache drips are optional (you could also spread the ganache on top of the cake if you'd rather)- but they are a great way to dress up a cake!

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!

Ingredients

For the Cake

  • 2 cups granulated sugar (400g)
  • 2 ¾ cup all-purpose flour (322g)
  • 1 cup unsweetened cocoa (lightly spoon into cup then sift) (82g)
  • 2 teaspoons baking soda (10g)
  • ½ teaspoon baking powder (2g)
  • ½ teaspoon salt (2g)
  • 2 sticks unsalted butter, softened (do not soften in microwave) (226g) It should be softened yet slightly firm when pressed.
  • ¼ cup vegetable oil (54g)
  • 4 large eggs at room temperature (If in a hurry, place in a bowl of warm water for 5 minutes.)
  • 1 teaspoon vanilla extract (4g)
  • 1 cup milk (220g)
  • 1 cup hot coffee, it can be instant or brewed (220g)

For the Ganache

  • 10 oz. Chocolate (Semi-sweet or Dark) We used Ghirardelli (283g)
  • 10 oz. Heavy Cream (283g)

For the Oreo Buttercream Frosting

  • 2 sticks unsalted butter, softened (226g)
  • 7 cups confectioners sugar (depending on desired consistency. More sugar=more crusting). (690g-805g)
  • 2 tsp. vanilla extract (8g)
  • ¼ cup whole milk or more if needed (60g)
  • ½ teaspoon salt (3g) to cut the sweetness. Adjust to taste.
  • Oreos- We used about 10 crushed Oreos for this recipe but use however many you'd like!

Instructions

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 the 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.

  1. Hi Karine, you don't have to chill your tier before applying the ganache drip, but if you'd like to firm the buttercream up a bit, 10 minutes in the freezer should do the trick!

  2. Hi melissa,

    I will make the cake a day before my sons birthday. Do i have to keep it in fridge or its ok in room temperature also. Im asking you because i want to cover it with sugarpaste.

  3. Hi Emma, the cake and buttercream are fine at room temp. The ganache, since it is a 1:1 ratio of chocolate to cream is a little iffy. Some might leave it at room temp, but for us, we like to play it safe and refrigerate. (Ganache with a 2:1 ratio of chocolate to cream is less perishable but also thicker). I hope this helps.

  4. I made this cake for our monthly birthday celebration at work. Everyone loved it. Super moist and delicious.

  5. Does the chocolate ganache need to be refrigerated if I have some left and want to use it for another recipe where the cake might not be stored in the fridge for a day or two?

  6. Hi Karen, The ganache, because it is a 1 to 1 ratio of chocolate to cream, does need to be refrigerated. When ready to serve your cake, remove it from the refrigerator about 2 hours before serving.
