Cookies and Cream Chocolate Cake

Unlike most cookies and cream cakes that start with vanilla cake, this one begins with rich dark chocolate layers, then piles on creamy Oreo filling and decadent chocolate fudge frosting. The result is a bakery-style layer cake that's equal parts dramatic, decadent, and completely worth washing an extra cake plate.

🥰 Is this cookies and cream chocolate cake recipe for you?

Make this cake if you:

• Think chocolate cake should taste unapologetically chocolatey.
• Never met an Oreo you didn't like.
• Need a bakery-worthy cake for birthdays and celebrations that's simple to make and has easy steps.
• Prefer homemade cakes that disappear faster than the candles burn.
• Believe licking the spatula is simply part of the cleanup process.

🧾 Ingredients

These simple ingredients come together to create rich chocolate flavor and moist, sturdy cake layers that won't collapse under all that deliciousness.

• All-purpose flour: The sturdy foundation that gives this cake enough structure to hold generous layers of filling and frosting without falling apart.
• Hershey's Special Dark Cocoa: I love Special Dark because it gives the cake a deep chocolate flavor and rich color. Regular unsweetened cocoa works if that's what you have.
• Granulated sugar: Sweetens the cake while helping create a tender, moist crumb.
• Baking soda: Works with the buttermilk to give the cake a beautiful rise and soft texture.
• Baking powder: Adds a little extra lift so each layer bakes up light without sacrificing structure.
• Kosher salt: A small amount makes a big difference by balancing the sweetness and bringing out the chocolate flavor.
• Butter: Use room-temperature butter so it creams properly and creates a light, tender cake.
• Vanilla: Rounds out the chocolate flavor and makes everything taste just a little richer.
• Eggs: Bind everything together while adding richness and helping the layers stay sturdy enough for stacking.
• Buttermilk: Keeps the cake moist and tender while reacting with the baking soda for an even crumb.
• Powdered sugar: The base of the creamy filling, giving it sweetness without a gritty texture.
• Heavy cream: Helps create a smooth, fluffy filling that's easy to spread between the cake layers.
• Oreo cookies: The star of the filling! Crush them into chunky pieces so every slice gets plenty of cookies-and-cream goodness.
• Chocolate Fudge Frosting: I finish this cake with my Chocolate Fudge Frosting because its deep chocolate flavor perfectly balances the sweet filling without stealing the spotlight. You can substitute your favorite chocolate frosting, but this one has been my go-to since the 1980s for a reason.

📖 Recipe

🔪 How to make cookies and cream chocolate cake

Layer cakes have a reputation for being fussy, but this one is surprisingly well-behaved… unlike the people waiting for the first slice.

1. Mix the dry ingredients. Whisk together the flour, cocoa, baking powder, baking soda, and salt until everything is evenly combined.
2. Cream the butter and sugar. Beat the butter and sugar until light and fluffy, then add the eggs one at a time, mixing well after each addition.
3. Add the first flour mixture. Beat in one-third of the dry ingredients just until combined.
4. Alternate the buttermilk and flour. Mix in half of the buttermilk, then another third of the flour. Repeat with the remaining buttermilk and finish with the last third of the flour. Mix just until no streaks of flour remain, being careful not to overmix.

5. Bake the cake layers. Divide the batter evenly between two prepared high-sided cake pans and bake until a toothpick inserted in the center comes out clean. Cool completely before assembling.
6. Prepare the filling. Make the filling according to the recipe, then chill it until it's easy to spread.
7. Assemble the cake. Split each cake layer in half to make four layers. Spread the filling evenly between each layer, finishing with a cake layer on top.
8. Frost and decorate. Cover the cake with Chocolate Fudge Frosting, then garnish with Oreo cookies before slicing and serving.

😱 What can go wrong (and how to fix it)

🍫 The cake sticks to the pan. Grease and line the pans with parchment before baking, then let the cakes cool for about 10 minutes before turning them out.

🍫 The layers slide around. If the cake or filling is too warm, everything starts skating across the plate. Chill the layers or the assembled cake for 20 to 30 minutes before frosting. I like to stick a couple of straws down through the assembled cake to hold the layers together.

🍫 The cake domes too much. Trim the rounded tops with a serrated knife so the layers stack evenly instead of leaning like they had a rough Saturday night.

🍫 The filling squishes out the sides. Don't spread the filling all the way to the edge. Leave about a ½-inch border so it has somewhere to go when the next layer settles on top.

🍫 The frosting is full of crumbs. Spread on a thin crumb coat first, chill the cake for 15 to 20 minutes, then finish with the final layer of frosting.

🍫 The cake seems dry. Be careful not to overbake. Pull the layers from the oven as soon as a toothpick comes out with a few moist crumbs attached. An instant read thermometer stuck in the center should read 205°F to 210°F.

🍫 The slices won't stay together. Chill the finished cake for 30 to 60 minutes before cutting. A cold cake makes cleaner slices and keeps those beautiful layers intact.

Cake Baking Tip: If you have trouble with your cake tops being domed try making a hollow in the center of the cake batter once it is in the pan It doesn't have to be real deep but the sides will rise a little differently than the center and your cake will be flat on top.

📚 More chocolate cakes to try

Obviously, this is not an everyday cake but for a special occasion, you won't find anything that tops this rich chocolate cake with the creamy Oreo filling!

Here is the deal. Each bite is perfectly balanced between cake and filling. The cake is moist, the frosting is creamy, the cookies add a nice crunch. This is a cake for those among us with a sweet tooth that may well have once belonged to a giant saber-toothed tiger.

Cut the slices thin and serve with espresso or a stout Earl Grey tea. We love this with a scoop of homemade French vanilla ice cream.
