Ingredients for the Best Chocolate Oreo Cake Recipe
Here’s what you’ll need to make this delicious cake:
For the Cake:
- 1 ¾ cups all-purpose flour
- 2 cups caster sugar
- ¾ cup unsweetened cocoa powder
- 2 teaspoons baking powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt
- 2 large eggs
- 1 cup whole milk
- ½ cup vegetable oil
- 2 teaspoons vanilla extract
- 1 cup warm water
For the Oreo Buttercream:
- 1 cup unsalted butter (room temperature)
- 4 cups powdered sugar
- 2 teaspoons vanilla extract
- 3–4 tablespoons milk (adjust as needed for consistency)
- 10 crushed Oreo cookies (for folding into the buttercream)
For the Topping:
- 9 whole Oreo cookies (for decoration)

How to Make the Perfect Chocolate Oreo Cake
Step 1: Prepare the Cake Batter
To begin, preheat your oven to 350°F (175°C) and grease and line two 9-inch cake pans with parchment paper.
- Mix the Dry Ingredients: In a large bowl, whisk together the all-purpose flour, caster sugar, cocoa powder, baking powder, baking soda, and salt. Ensure that everything is well combined to avoid lumps.
- Combine the Wet Ingredients: In a separate bowl, whisk together the eggs, milk, vegetable oil, and vanilla extract until smooth. Slowly incorporate the dry ingredients into the wet mixture.
- Add Warm Water: Gently whisk in the warm water. The batter will be thin, but don’t worry—this will ensure your cake comes out moist and tender.
- Bake the Cake: Pour the batter evenly into the prepared cake pans. Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.
Step 2: Make the Oreo Buttercream Icing
The secret to a truly indulgent Oreo buttercream icing is the perfect balance of creaminess and crunch. Here’s how to make it:
- Whip the Butter: In a large bowl, beat the softened butter using an electric mixer until creamy and light. This usually takes about 3-4 minutes.
- Add the Sugar: Gradually add the powdered sugar, one cup at a time, beating continuously. Add the vanilla extract and a tablespoon of milk if needed to reach the desired consistency.
- Fold in the Oreos: Once the buttercream is smooth and fluffy, gently fold in the crushed Oreo cookies. Be careful not to overmix— you want chunks of Oreo throughout the icing for that extra texture and flavor.
Step 3: Assemble the Cake
- Frost the Cake: Once the cakes are completely cooled, spread a generous layer of the Oreo buttercream on top of one cake layer. Place the second cake layer on top and frost the entire outside of the cake with the remaining buttercream, smoothing it evenly with a spatula.
- Decorate: For an extra touch of indulgence, top the cake with whole Oreo cookies. You can either place them neatly around the edges or crumble them for a more rustic finish.
- Chill the Cake: If possible, let the cake chill for 30 minutes before slicing. This will allow the buttercream to set and make cutting the cake easier.

Tips for Making the Best Oreo Chocolate Cake
- Don’t overmix: When folding in the crushed Oreos into the buttercream, be sure to gently fold rather than vigorously mix. This will prevent the buttercream from becoming too soft and ensure that you get a nice crunch from the Oreos.
- Use room temperature ingredients: Allow your eggs, milk, and butter to come to room temperature before mixing. This helps create a smoother batter and more stable buttercream.
- Upgrade with a twist: If you want to try something new, consider turning this recipe into a mint Oreo cake by adding a few drops of mint extract to the buttercream or cake batter. Or, if you’re feeling adventurous, try a layered chocolate pudding dirt cake by adding a layer of chocolate pudding between the cake layers!
