This Chocolate Oreo Cake is to die for. Three layers of moist chocolate cake are filled and frosted with chocolaty, Oreo-packed buttercream, plus more Oreos are layered between the cake layers. It’s an Oreo lover’s dream.

Rich & Decadent Chocolate Oreo Cake

I am such a big fan of desserts made with Oreos, as you can see with from all my dessert recipes made with Oreos. The flavor is just so good. This cake combines the wonderful Oreo cookie with cake and chocolate. The result is one delicious dessert that is nothing short of a dream come true.

Three layers of tender, moist chocolate cake are stacked on top of one another, filled with thick layers of fluffy, Oreo-filled buttercream. Between each cake layer there is also more chopped Oreos! There’s no shortage of Oreo flavor in this cake! It is then frosted with more Oreo buttercream, drizzled with a rich chocolate ganache, and decorated with buttercream swirls and whole Oreos. It’s practically irresistible.

And even better – it’s super easy to make! The chocolate cake itself is my classic chocolate cake recipe that is super moist and gets into the oven in about 10 minutes. The buttercream is also a classic vanilla buttercream that’s easy to make – you just have to grind up the Oreos to flavor it!

Why You’ll Love This Chocolate Cake with Oreo Buttercream

Chocolate cake plus Oreos? What’s not to love!? Here are some of my favorite things about this delicious dessert.

  • Packed with Oreos. If you love Oreos as much as I do, this is the cake for you. The recipe uses an entire package of these delicious sandwich cookies. Between the frosting and the garnish, you will not miss an Oreo in a single bite.
  • The cake is so moist. The layers of cake themselves are some of the moistest ever. Your search for the perfect chocolate cake is over. It’s amazing. 
  • No fancy mixing method. Some cakes require a lot of fancy whipping, fluffing, and folding. Not this one. Just mix everything together right in the bowl. It’s as simple as that.

What You’ll Need

Here is a list of ingredients you will need to make this decadent, Oreo-filled chocolate layer cake. Don’t forget to scroll to the recipe card below for exact measurements.

Chocolate cake

  • All-purpose flour – Feel free to use your favorite 1:1 gluten-free substitute instead.
  • Sugar
  • Natural unsweetened cocoa powder – You can use dutch processed cocoa powder for a more bitter chocolate flavor.
  • Baking soda – For the optimal rise and cake texture.
  • Salt – For flavor. Don’t leave it out.
  • Large eggs – It is best if the eggs are at room temperature. They will incorporate into the batter more easily, helping to prevent over-mixing.
  • Milk – For more moisture and fat.
  • Vegetable oil – For a super moist cake.
  • Vanilla extract – For a little extra flavor.
  • Boiling water – The hot water will help the flavors in the cocoa powder “bloom”, yielding a more powerful chocolate flavor.

Oreo Buttercream

  • Butter – The butter should be at room temperature.
  • Powdered sugar – For volume and consistency.
  • Oreo crumbs – To flavor the buttercream. I like to put my Oreos in a food processor and grind into crumbs.
  • Vanilla extract – Also for flavor.
  • Heavy cream – To give the frosting creaminess and the best consistency.
  • Oreos

Chocolate Ganache and Toppings

  • Semi-sweet chocolate chips
  • Heavy whipping cream
  • Oreos

How to Make Chocolate Oreo Cake

Cake. Buttercream. Ganache. Just three simple components and you’ll be ready to assemble one of the best layer cakes on the planet. Here’s how to do it. Make sure to scroll to the recipe card below for more detailed instructions.

Chocolate cake

  • Prep. Preheat the oven to 300 degrees F, line the bottom of three 8-inch cake pans with parchment paper circles, and grease the sides.
  • Make the cake batter. Whisk together the dry ingredients. Add eggs, milk, and vegetable oil and mix to combine. Add vanilla to the boiling water and mix into the batter.
  • Bake. Divide batter between the three cake pans and bake for 30-33 minutes. Allow the cakes to cool for 5-10 minutes before turning them out onto a cooling rack to cool completely.

Oreo buttercream

  • Beat the butter until smooth.
  • Mix in half of the powdered sugar followed by the vanilla and Oreo crumbs. Mix in the rest of the powdered sugar. Slowly mix in the heavy cream until you get a smooth consistency.

  • Set aside 3 1/2 cups of the buttercream and add chopped Oreos to the rest.

To assemble

  • Level the cakes. Use a serrated knife to remove the cake domes.
  • Stack and fill. Place first layer of cake on cake plate and spread half of the icing with chopped Oreos on top in an even layer. Repeat with the second cake and the second half of the icing with Oreos. Top with the last cake layer.
  • Frost the outside of the cake with the remaining frosting.
  • Make the chocolate ganache. Heat the heavy whipping cream until it begins to boil. Pour it over the chocolate chips. Allow it to sit for 2-3 minutes and whisk until smooth.

  • Finish the cake. Drizzle the chocolate ganache around the edge of the cake and spread the remainder over the top. Allow the ganache to firm up before piping the remainder of the frosting around the top edge of the cake. Add Oreos between swirls.

Can This Chocolate Layer Cake Be Prepared in Advance?

Yes! You can prepare all of the elements for this cake (aside from the ganache) in advance. Bake the cakes, allow them to cool, and store them in an air-tight container or cake carrier (or wrap them in clear wrap) until you are ready to assemble the cake. You can also make the buttercream a day or two in advance so long as you store it in an airtight container in the refrigerator.

When you are ready to enjoy this delicious dessert, bring your buttercream to room temperature (it’ll be very hard straight out of the fridge). Then all you have to do is stack, fill, frost, and decorate the cake.

Tips for Success

Layer cakes can feel intimidating, I get it. Rest assured, though. This chocolate Oreo cake will turn out perfectly if you follow a few simple tips and tricks.

  • Measure carefully. Especially the flour. If you don’t have a food scale, I recommend spooning the flour into the measuring cup and leveling it.
  • Room temperature ingredients. The eggs in the cake batter as well as the butter in the buttercream should be at room temperature before beginning. The eggs will incorporate into the batter more easily, preventing you from over-mixing. Starting with room-temperature butter will set you up for a smooth, creamy buttercream as opposed to a lumpy one.
  • Don’t over-mix the batter. Over-mixing the batter will cause the glutens in the flour to overdevelop giving you a tough, overly dense cake.
  • Frost with ease. Check out my tutorial for how to frost a smooth cake while the cake is cooling.
  • Study up on how to make the perfect chocolate ganache.

Serving Suggestions

This chocolate layer cake is magnificent on its own but that doesn’t mean you can’t doll it up with a topping or two or wash it down with a delicious beverage. Here are some of my favorite ways to serve it.

How to Store Leftovers

If you find yourself with leftovers, store this cake in an airtight cake carrier in the refrigerator for up to 4 days. No cake carrier? No problem. Wrap the cake in a double layer of saran wrap and store it in the refrigerator. Use toothpicks to prop the plastic away from the cake decorations. Already sliced it? Arrange the slices in a single layer in an airtight container and store them in the refrigerator.

If you want to freeze the cake, do so before assembling it. Wrap the cooled cake layers in clear wrap and aluminum foil and store them in the freezer for up to 3 months. When you are ready to enjoy, allow the layers to thaw in the refrigerator before stacking, frosting, and decorating.

Description

This Chocolate Oreo Cake is to die for! A moist chocolate cake full of Oreo icing! And not just any Oreo icing – it is FULL of crushed up Oreos. An Oreo lover’s dream.


Ingredients

Chocolate Cake

  • 2 cups (260g) all-purpose flour (measured properly)
  • 2 cups (414g) sugar
  • 3/4 cup (85g) natural unsweetened cocoa powder
  • 2 tsp baking soda
  • 1 tsp salt
  • 2 large eggs
  • 1 cup (240ml) milk
  • 1 cup (240ml) vegetable oil
  • 1 1/2 tsp vanilla extract
  • 1 cup (240ml) boiling water

Oreo Buttercream and Chopped Oreo Filling

  • 3 cups (672g) unsalted butter, room temperature
  • 89 cups (920g-1035g) powdered sugar
  • 3 cups (414g) Oreo crumbs (about 33 Oreos)
  • 1 tsp vanilla extract
  • 67 tbsp (90ml-105ml) heavy cream
  • pinch of salt
  • 12 Oreos, chopped

Chocolate Ganache

  • 6 oz (1 cup | 169g) semi-sweet chocolate chips
  • 1/2 cup (120ml) heavy whipping cream
  • Oreos, optional

NOTE: You’ll need at least one full package of Oreos. If you plan to decorate the outside of the cake with more Oreos, as shown, you might need a second package.


Instructions

  1. Make the cakes. Prepare three 8 inch cake pans with parchment paper circles in the bottom, and grease the sides.
  2. Add all dry ingredients to a large bowl and whisk together.
  3. Add eggs, milk and vegetable oil to the dry ingredients and mix well.
  4. Add vanilla to boiling water and add to mixture. Mix well.
  5. Divide batter between three cakes pans and bake at 300 degrees for about 30-33 minutes, or until a toothpick comes out with a few crumbs.
  6. Remove cakes from oven and allow to cool for about 10 minutes, then remove to cooling racks to cool completely.
  7. Make icing while cakes cool. Beat together butter until smooth.
  8. Slowly add 4 cups of powdered sugar and mix until smooth.
  9. Add vanilla, Oreo crumbs and salt and mix until smooth.
  10. Add another 4-5 cups of powdered sugar and mix until smooth. Add heavy cream, as needed, until you get a smooth consistency.
  11. To make the filling for inside the cake, measure out about 3 1/2 cups of Oreo buttercream and add chopped Oreos. Set chopped Oreo filling aside. Set remaining Oreo buttercream aside as well.
  12. Assemble the cake. Once cakes are cool, remove cake domes from top with a large serrated knife.
  13. Place first layer of cake on cake plate. Spread 1/2 of the chopped Oreo filling on top in an even layer.
  14. Add second layer of cake and add the rest of the chopped Oreo filling on top in an even layer.
  15. Add final layer of cake on top and frost the outside of the cake with the Oreo buttercream frosting. Feel free to use my tutorial for how to frost a smooth cake.
  16. To make the chocolate ganache, add the chocolate chips to a medium sized bowl (see my tips on making chocolate ganache).
  17. Heat the heavy whipping cream just until it begins to boil, then pour it over the chocolate chips. Allow it to sit for 2-3 minutes, then whisk until smooth.
  18. Drizzle the chocolate ganache around the edge of the cake, then pour the remainder of the ganache on top of the cake and spread evenly. I like to use a squeeze bottle for drizzling around the edges.
  19. Allow the ganache to firm up a bit, then pipe the remainder of the frosting around the top edge of the cake (see my tips on making a chocolate drip cake) and add an Oreo between each swirl. I used Ateco tip 844.
  20. Sprinkle a few Oreo crumbs onto to the cake, if desired, then serve. Cake is best when well covered for 3-4 days.

Notes

Feel free to reduce the overall amount of buttercream if you plan on decorating your cake differently. I use a fair amount based on my method of how to decorate a smooth cake (linked in the recipe instructions above).

    I’m confused – the top part says to store in the fridge but on the bottom, it just says to store in an airtight covered container… so does it have to go in the fridge or can it be stored at room temp?

    1. Lindsay

      So it’s a little bit of both. It can be stored at room temperature for about 24 hours, but because of the buttercream should be put in the fridge after that.

  2. David Wright

    When do you put the heavy cream into the filling? I can see it in the ingredients but not in the instructions which say to add water or milk.

    1. Lindsay

      It was slightly adjusted. It’s the same recipe. It did use buttermilk. You can use either regular milk or buttermilk. And I believe it used to have half butter and half shortening in the frosting and now it’s all butter. Otherwise I’m pretty sure it’s exactly the same.

  3. Jamie eding

    Does this cake recipe make about the same amount one one boxed mix? Trying to decide how much I need to make. It looks delicious!!
    Thank you

    1. Lindsay

      Yes, these cakes do very well with being frozen. Just wrap them well before freezing, and then thaw them in the fridge before using.

  4. Dingle Hopper

    Hello there im wanting to use a sugar alternative such as Pure Via or Truvia do i just replace these like for like? very excited to try this recipe thank you

    1. Tracey

      I do not know if a sugar alternative will work for this particular recipe, but I have always used cup for cup to replace sugar in a recipe with a sugar alternative. I hope this helps!

  5. Nicole

    Hello! Your old recipe was my go to for anything I had to bring dessert to but I always just went on the site for it. Do you have a copy of the old recipe you could share with me?

    1. Lindsay

      The recipes hasn’t changed, the post was just updated with some step by step pictures and additional information.

  6. Amy Bridenbaugh

    I need a larger cake to serve more people. Do you think this cake will work if I make two batches of the cake batter and use 10inch pans?

  7. Zein

    Hi, this is my go-to recipe but I didn’t re-write it. Am making it today with butter instead of shortening. But can you let me know how much shortening the original recipe called for?






  8. Matt

    Good recipe. I used 1 cup (8oz setting on Keurig) of hot coffee in place of the water to add richer chocolate flavor. Also I used two 9″ cake pans (about 775g of batter in each) and baked at 300 degrees for exactly 45 minutes and they turned out perfect!

  9. Matt

    Wondering if I could substitute the 1 cup hot water with 1 cup hot coffee? I’ve heard that enhances the chocolate flavor?

    1. Lindsay

      You certainly can. The heat in the hot water makes the cocoa bloom, which enhances the chocolate flavor as well. I don’t really feel like the coffee is necessary, but it certainly doesn’t hurt anything if you’d like to add it.

  10. Arlene Fraher

    Three cups of butter seems like it would make an enormous amount of buttercream frosting! Will I really use it all for the three layers? Or is there a way to make less?

  11. Jen

    This looks amazing. Can I make it on a Wednesday and keep it in the fridge if I need it for Friday? Just wondering if it will still be moist if not served the same day?

    1. Lindsay

      This is a super moist cake and holds up very well. That should be fine. I would just bring the cake back to room temperature before serving.
