How to Make Chocolate Oreo Cake
This Chocolate Oreo Cake recipe is designed for pure indulgence with minimal fuss, promising a moist, rich chocolate base studded with delightful Oreo chunks. The creamy, decadent Oreo frosting, generously swirled with even more crushed cookies, takes it to the next level. With a preparation time of about 30 minutes and baking for roughly 30-35 minutes, you’ll have a show-stopping dessert ready to impress.
Step-by-Step Instructions
- Preheat Oven and Prepare Pans: Preheat your oven to 350°F (175°C). Grease and flour two 8-inch or 9-inch round cake pans. You can also line the bottoms with parchment paper for easier removal.
- Combine Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, unsweetened cocoa powder, baking soda, baking powder, and salt. Ensure all ingredients are well combined to avoid lumps.
- Combine Wet Ingredients: In a separate medium bowl, beat the eggs lightly. Then, whisk in the buttermilk, vegetable oil, and vanilla extract until smooth.
- Combine Wet and Dry: Pour the wet ingredients into the dry ingredients and mix on low speed (or by hand with a whisk) until just combined. Be careful not to overmix.
- Add Hot Liquid: Gradually add the hot water or hot coffee to the batter while mixing on low speed. The batter will be thin; this is normal and contributes to the cake’s moisture.
- Fold in Oreos: Gently fold in the roughly chopped Oreo cookies into the batter until evenly distributed. Reserve a few chopped Oreos for garnish if desired.
- Pour into Pans: Divide the batter evenly between the prepared cake pans.
- Bake: Bake for 30-35 minutes, or until a wooden skewer or toothpick inserted into the center of the cakes comes out clean.
- Cool the Cakes: Let the cakes cool in the pans for about 10-15 minutes before inverting them onto a wire rack to cool completely. Ensure they are fully cooled before frosting.
- Prepare the Oreo Frosting: While the cakes are cooling, make the frosting. In a large bowl, beat the softened unsalted butter until creamy and smooth.
- Add Powdered Sugar and Cocoa: Gradually add the sifted powdered sugar and cocoa powder to the butter, alternating with the milk (or cream), mixing on low speed until incorporated. Scrape down the sides of the bowl as needed.
- Add Vanilla and Crushed Oreos: Add the vanilla extract and mix until smooth. Fold in the ½ cup of crushed Oreos until they are evenly distributed throughout the frosting.
- Frost the Cake: Once the cakes are completely cooled, place one cake layer on your serving plate. Spread a generous amount of Oreo frosting over the top. Place the second cake layer on top and frost the entire cake, including the sides, with the remaining frosting.
- Garnish: Decorate the top of the cake with additional crushed Oreos or whole Oreos, as desired.

Storing and Reheating Tips
Properly storing and reheating your Chocolate Oreo Cake will ensure it stays delicious for days.
- Refrigeration: Once frosted, the cake is best stored in an airtight container or covered tightly with plastic wrap and then foil to prevent it from drying out. It will stay fresh in the refrigerator for up to 3-4 days.
- Room Temperature: If the cake is unfrosted or has a stable frosting (like a buttercream without cream cheese), it can be stored at room temperature for 1-2 days in an airtight container. However, for optimal freshness and to preserve the integrity of the frosting, refrigeration is recommended.
- Freezing: For longer storage, you can freeze the cake.
- Frosted Cake: It’s best to freeze frosted cake in slices. Wrap individual slices tightly in plastic wrap, then in aluminum foil. Place wrapped slices in a freezer-safe bag or container. It can be stored in the freezer for up to 2-3 months.
- Unfrosted Cake Layers: Allow unfrosted cake layers to cool completely. Wrap each layer tightly in plastic wrap, then in aluminum foil. Place in a freezer-safe bag or container. Can be frozen for up to 3 months.
- Reheating:
- Frosted Cake: If refrigerated, allow the cake to sit at room temperature for about 20-30 minutes before serving to soften the frosting and cake. If frozen, thaw overnight in the refrigerator, then bring to room temperature before serving.
- Unfrosted Cake Layers: Thaw overnight in the refrigerator or at room temperature for a few hours. Once thawed, they can be layered and frosted as usual.
