Why You’ll Love this Triple-Layer Chocolate Oreo Cake
When you’re craving something truly decadent, this Triple-Layer Chocolate Oreo Cake delivers on every level. I mean, who can resist the combination of moist chocolate cake and Oreo buttercream frosting? It’s practically irresistible.
The three layers create that impressive height that makes everyone at the table go “wow” before they even take a bite. Trust me, the rich cocoa flavor paired with chunks of Oreo cookies in the frosting is a match made in dessert heaven.

What Ingredients are in Triple-Layer Chocolate Oreo Cake?
This show-stopping chocolate cake with Oreo buttercream frosting requires a mix of pantry staples and a few special items that come together beautifully.
- 2 cups all-purpose flour
- 1 cup cocoa powder
- 2 cups granulated sugar
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- 2 cups buttermilk
- 2 eggs
- ½ cup oil
- 1½ cups butter
- 6 cups powdered sugar
- 1 cup Oreo cookie crumbs
- Heavy cream (for the frosting)
When shopping for ingredients, I recommend using high-quality cocoa powder for the richest chocolate flavor, and make sure your Oreos are processed finely enough for smooth frosting but with enough texture to give that signature cookies-and-cream taste.
How to Make this Triple-Layer Chocolate Oreo Cake
Step 1: Prepare Your Pans and Preheat the Oven
Before diving into the mixing, grease three 8-inch cake pans and line them with parchment paper.
Preheat your oven to 350°F so it’s perfectly hot when your batter is ready.
Step 2: Mix the Dry Ingredients
In a large bowl, whisk together 2 cups all-purpose flour, 1 cup cocoa powder, 2 cups sugar, 1 teaspoon baking soda, and 1 teaspoon baking powder.
This creates the foundation of our deeply chocolatey cake layers.
Step 3: Combine the Wet Ingredients
In a separate bowl, mix 2 cups buttermilk, 2 eggs, and ½ cup oil until well combined.
The buttermilk adds a wonderful tenderness and slight tang that balances the sweetness.
Step 4: Create Your Cake Batter
Pour the wet ingredients into the dry ingredients and mix until just combined.
You want a smooth batter without overmixing, which can make your cake tough rather than tender.
Using a stand mixer would make this process much easier and ensure perfectly mixed batter without overworking the ingredients.
Step 5: Bake the Cake Layers
Divide the batter evenly among the three prepared pans and bake for 40-45 minutes, or until a toothpick inserted in the center comes out clean.
The kitchen will smell absolutely divine as these bake.
Step 6: Cool the Cake Completely
Allow the cake layers to cool in their pans for about 10 minutes, then remove them to a wire rack to cool completely.
Patience is key here—warm cakes and buttercream are a disaster waiting to happen.
Step 7: Make the Oreo Buttercream Frosting
Beat 1½ cups butter until smooth and creamy, then gradually add 6 cups powdered sugar and a splash of heavy cream.
Once fluffy and light, gently fold in 1 cup of finely crushed Oreo crumbs for that cookies-and-cream magic.
Step 8: Assemble and Frost the Cake
Place one cake layer on your serving plate, spread a generous layer of frosting on top, then repeat with the remaining layers.
Cover the entire cake with the remaining Oreo buttercream, creating swirls and peaks for a rustic yet elegant finish.
What to Serve with Triple-Layer Chocolate Oreo Cake
This decadent cake deserves some thoughtful accompaniments to round out your dessert experience.
A scoop of vanilla bean ice cream alongside a slice creates that perfect hot-and-cold contrast, especially if the cake is slightly warmed. For a revitalizing counterpoint, fresh berries—strawberries, raspberries, or blueberries—add a touch of tartness and beautiful color to the plate.
Coffee lovers will appreciate a strong espresso or cappuccino to cut through the richness, while a cold glass of milk is the classic choice for chocolate enthusiasts.
For something special, try serving with a drizzle of warm chocolate ganache or homemade raspberry sauce. This showstopper works beautifully as an afternoon treat with tea or as the grand finale to any celebration dinner.

Leftovers and Storage for this Triple-Layer Chocolate Oreo Cake
This decadent cake stores beautifully for several days when properly stored. Here’s how to keep it tasting its best:
- Store leftover cake in an airtight container in the refrigerator for up to 5 days. The buttercream will firm up when chilled, which some folks actually prefer.
- For longer storage, freeze individual slices wrapped tightly in plastic wrap, then aluminum foil. They’ll keep for up to 3 months. Who doesn’t love finding cake in their freezer?
- When ready to enjoy, let refrigerated cake sit at room temperature for 20-30 minutes before serving to soften the frosting and enhance the flavor.
- To prevent drying out, always cut with a clean, sharp knife and cover the exposed cake layers with plastic wrap.
Interestingly, many find this cake tastes even better on day two, when the flavors have had time to meld together!
