Chocolate Oreo Cake

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

• 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

• Flatten 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.

• Ice cream. Serve this Oreo cake with a scoop of vanilla ice cream. Feeling adventurous? Whip up a batch of my Oatmeal Chocolate Chip Cookie Ice Cream or this Birthday Cake Ice Cream.
• Whipped cream. Pick up a tub of Cool Whip or hop in the kitchen and make Homemade Whipped Cream Recipe. You could even try my Baileys Chocolate Whipped Cream. Yum.
• Sauce. Drizzle this Easy Caramel Sauce or my Easy Homemade Hot Fudge Sauce over a slice of this chocolate cake with oreo buttercream.

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.
