Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the Chocolate Cake:
- 2 cups all-purpose flour
- 1 ¾ cups granulated sugar
- ¾ cup unsweetened cocoa powder
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- ½ teaspoon salt
- 1 cup buttermilk (or 1 cup milk + 1 tbsp vinegar)
- ½ cup vegetable oil
- 2 large eggs
- 2 teaspoons vanilla extract
- 1 cup hot coffee (or hot water)
- 1 cup crushed Oreo cookies (about 10 Oreos)
For the Oreo Frosting:
- 1 cup (2 sticks) unsalted butter, softened
- 4 cups powdered sugar
- ¼ cup heavy cream (or milk)
- 1 teaspoon vanilla extract
- 12 Oreos, crushed into fine crumbs
For Topping:
- Whole Oreos (for decoration)
- Crushed Oreos (for sprinkling)
Instructions
Step 1: Make the Chocolate Cake
- Preheat the oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper. You want to make sure the cake comes out of the pans easily, so don’t skip this step!
- Mix dry ingredients: In a large mixing bowl, whisk together flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt. This will help to evenly distribute the dry ingredients before adding the wet ones.
- Add wet ingredients: To the dry ingredients, add the buttermilk, vegetable oil, eggs, and vanilla extract. Mix everything together until it’s fully combined. Don’t worry if the batter looks a little thick at this stage—that’s totally normal.
- Add coffee: Now, pour in the hot coffee. This step might seem a little strange, but trust me, it makes the cake incredibly moist. The batter will be thin, but that’s exactly how it should be!
- Fold in the Oreos: Gently fold in the crushed Oreos. You’ll get bits of Oreo cookie throughout the batter, adding a fun and flavorful twist to each bite.
- Bake: Divide the batter evenly between the two cake pans and bake for 30-35 minutes. To check if the cakes are done, insert a toothpick into the center—if it comes out clean, they’re ready. Once baked, let the cakes cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

Step 2: Make the Oreo Frosting
- Beat the butter: In a large mixing bowl, beat the softened butter until it’s creamy and smooth. You’ll want this to be light and fluffy before adding anything else.
- Add powdered sugar: Gradually add in the powdered sugar, one cup at a time, mixing after each addition. This ensures the frosting is smooth and creamy without any lumps.
- Add the cream and vanilla: Pour in the heavy cream (or milk, if that’s what you have on hand) and vanilla extract. Beat the frosting on high speed until it’s light and fluffy.
- Add crushed Oreos: Now, fold in the crushed Oreos. The more Oreos, the better! This gives the frosting a chunky, cookies-and-cream texture that’s simply irresistible.
Step 3: Assemble the Cake
- Layer the cake: Place one of the cooled cake layers onto a serving platter or cake stand. Spread a generous amount of Oreo frosting on top, smoothing it out with a spatula. Don’t be shy with the frosting—this is the star of the show!
- Top with second layer: Add the second cake layer on top of the frosted layer. Then, cover the entire cake with the remaining Oreo frosting, making sure every inch is covered with that creamy goodness.
- Decorate: To finish, decorate the top of the cake with whole Oreos placed around the edges and sprinkle crushed Oreos on top for an extra cookie crunch. If you’re feeling extra indulgent, drizzle some chocolate ganache over the top for that added touch of decadence.
- Chill: Refrigerate the cake for about 30 minutes to let everything set. This will make slicing easier and help the frosting firm up a bit. Plus, it makes the cake even more refreshing when served cold!

Variations

- Oreo Ice Cream Cake: For a fun twist, layer the cake with cookies-and-cream ice cream instead of frosting. You’ll get an extra creamy, cool treat.
- Extra Chocolatey: If you love chocolate, add chocolate chips to the cake batter for double the chocolatey goodness.
- Gluten-Free Option: For a gluten-free version, swap the all-purpose flour with a gluten-free flour blend and make sure to use gluten-free Oreos.
- Peanut Butter Oreo Cake: Add a spoonful of peanut butter to the frosting for a nutty, salty-sweet combo that’ll blow your taste buds away.
Storage and Reheating
- Room temperature: The cake stays fresh at room temperature for about 1-2 days. Just make sure it’s stored in an airtight container to prevent it from drying out.
- Refrigerator: If you need to store it longer, pop it in the fridge. It will keep well for up to 5 days. Let it come to room temperature before serving for the best flavor and texture.

FAQs
- Can I make this cake without coffee? Yes! You can replace the hot coffee with hot water or milk if you prefer not to use coffee.
- How do I keep my cake from being dry? The secret is using buttermilk, which helps keep the cake moist. Also, make sure not to overbake—check the cake with a toothpick to ensure it’s done.
- Can I use store-bought frosting? While you can use store-bought frosting in a pinch, homemade Oreo frosting is much more flavorful and adds that special touch.
- How do I crush Oreos for the frosting? A food processor works best for this, but if you don’t have one, you can place the Oreos in a sealed plastic bag and crush them with a rolling pin.
- Can I make this cake ahead of time? Absolutely! You can bake the cakes a day ahead and frost them right before serving.
- Can I use a cake mix? Yes! If you’re short on time, you can use a chocolate cake mix and add crushed Oreos for extra flavor.
- How do I make this a three-layer cake? Divide the batter into three 8-inch cake pans and adjust the baking time accordingly (it will be a bit shorter, so keep an eye on it!).
- What’s the best way to frost a cake neatly? Chill your cake layers before frosting them. This makes the frosting go on smoother and gives you a nice, even coat.
- Can I add a ganache topping? Absolutely! A drizzle of melted chocolate ganache over the top will add a luxurious touch to the cake.
- What can I serve with Oreo cake? It pairs wonderfully with a scoop of vanilla ice cream or a cold glass of milk!
