- 4 to 5 cups Powdered Sugar, sifted
- 3 to 4 tbsp Heavy Cream
- 1 tsp Pure Vanilla Extract

How to Make This Chocolate Oreo Cake Recipe
Preheat the oven to 350°F (175°C). Grease and line three 8-inch round cake pans.
In a large bowl, whisk together the flour, Dutch cocoa, baking soda, baking powder, salt, and sugar until the most evenly combined. Add the eggs, sour cream, oil, and vanilla and mix until combined. Carefully stir in the most hot brewed coffee — the batter will be the most beautifully thin. Pour evenly among the three prepared pans, cara mia.
Bake for 22 to 25 minutes until a toothpick comes out with only a few moist crumbs. Cool 10 minutes then transfer to wire racks to cool completely.
For the individual Oreo cream buttercream, process the 20 whole Oreo cookies — with filling intact — in a food processor until the most fine individual crumbs with no visible individual cookie pieces. Beat the room-temperature butter for 3 minutes until the most pale and fluffy. Add the Oreo crumbs and beat until the most incorporated. Gradually add sifted powdered sugar, cream, vanilla, and salt. Beat for 3 minutes until the most incredibly fluffy.
For the ganache, heat the cream to just simmering, pour over the chocolate chips, rest 2 minutes, and whisk smooth. Cool to drizzle-able consistency.
Assemble the three individual layers with generous Oreo cream buttercream between each. Apply thin crumb coat, refrigerate 20 minutes, apply final frosting. Pour cooled ganache over the most top allowing the most dramatic drips. Press whole Oreo cookies into the most fresh frosting around the individual exterior. Scatter crushed Oreo crumbs.
How to Serve This Chocolate Oreo Cake Recipe
Serve at room temperature after 30 minutes out of the refrigerator for the most beautifully softened individual Oreo cream buttercream. The most dramatic individual chocolate ganache drip and the most whole individual Oreo cookies pressed into the individual exterior frosting create the most completely extraordinary and the most genuinely professional individual cake presentation.
For the most completely extraordinary individual Oreo birthday celebration, pipe additional individual Oreo cream buttercream rosettes around the most top edge of the individual finished cake between the most individual ganache drip and place individual whole Oreo cookies in each most rosette for the most beautifully abundant and the most properly show-stopping individual Oreo chocolate cake. Our Oreo Cake with Cookies makes a beautifully equally Oreo-every-component and equally spectacular companion for a complete and wonderful Oreo cake collection.
How to Store This Chocolate Oreo Cake Recipe
Refrigerate in an airtight container for up to 5 days. Allow 30 minutes at room temperature before serving for the most properly softened individual Oreo cream buttercream. Freeze individual unfrosted layers for up to 3 months.
Tips to Make This Chocolate Oreo Cake Recipe

Process the whole individual Oreo cookies — with their filling intact — to the most completely fine individual crumbs with no visible individual cookie pieces for the most smoothly spreadable and the most consistently Oreo-flavored individual buttercream. Any remaining the most visible individual cookie chunks produce the most uneven individual texture in the most spread individual frosting and the most clog individual piping tips.
The most hot brewed coffee in the individual chocolate sour cream cake batter must be the most genuinely hot — not the most simply warm — for the most effective and the most complete individual cocoa bloom that produces the most dramatically intensified and the most beautifully deep individual chocolate flavor throughout every individual crumb.
Helpful Notes for This Chocolate Oreo Cake Recipe
Dutch-processed cocoa is the most specifically essential for the most beautifully dark and the most deeply chocolatey individual sour cream cake layers — the most alkalizing process produces the most dramatically dark individual color that provides the most stunning visual contrast against the most bright individual Oreo cream buttercream and the most whole individual white-centered Oreo cookie decoration.
For the most beautifully controlled and the most properly dramatic individual ganache drip, chill the most completely frosted individual cake for 20 minutes before drizzling the most cooled individual ganache around the most top edge — the most cold individual frosting helps the ganache individual drip set the most quickly and the most cleanly for the most beautifully defined individual drip edges.
Variation of This Chocolate Oreo Cake Recipe
Maria made a version using Golden Oreos in the most individual buttercream for the most completely extraordinary and the most gorgeously golden individual vanilla Oreo cream buttercream on the most deeply dark individual chocolate layers. Teresa tried adding half a cup of the most individually chocolate chips through the individual chocolate cake batter alongside the most hot coffee for the most completely extraordinary and the most deeply triple-chocolate individual sour cream chocolate Oreo chip cake.
For a cookies-and-cream ice cream version, spread softened individual cookies-and-cream ice cream between the individual layers rather than individual Oreo buttercream for the most completely extraordinary and the most properly frozen individual chocolate Oreo ice cream cake. Our Oreo Cheesecake Recipe makes a beautifully equally Oreo-spectacular and equally celebration-worthy companion for a complete and wonderful Oreo dessert collection.
FAQs About This Chocolate Oreo Cake Recipe
Why are the Oreos processed with their filling?
Processing the most whole individual Oreo cookies with the most filling intact is the most specifically important individual technique for the most authentically Oreo-flavored and the most properly sweet individual buttercream — the most individual cream filling contributes the most essential additional sweetness, the most natural individual fat for the most proper individual buttercream texture, and the most specifically Oreo-authentic individual flavor that the most wafer-only individual approach cannot replicate with the most same genuinely extraordinary individual Oreo character.
How does this differ from the other Oreo Cake recipe?
This most specific individual version uses Dutch-processed cocoa rather than the most natural cocoa for the most dramatically darker and the most more sophisticated individual chocolate base, uses the most processed-to-crumb individual Oreo buttercream rather than folded individual Oreo pieces for the most consistently smooth and the most evenly spreadable individual Oreo frosting, and features the most ganache drip as the most finishing individual element rather than simply the most Oreo garnish for the most truly professional and the most genuinely extraordinary individual multi-element individual Oreo chocolate celebration cake.
Can I bake this in two 9-inch pans instead of three 8-inch?
Yes — divide the individual batter between two greased and lined 9-inch individual round pans and bake for approximately 28 to 32 minutes at 350°F for the most equally extraordinary individual two-layer individual chocolate Oreo celebration cake with the same most beautifully spreadable individual Oreo cream buttercream and the most dramatic individual ganache drip.
Conclusion
This Chocolate Oreo Cake is the most completely extraordinary and the most genuinely spectacular three-layer Dutch cocoa sour cream chocolate celebration cake that makes every birthday and every gathering feel genuinely and completely magnificent through the most deeply chocolatey layers and the most beautifully smooth Oreo cream buttercream and the most dramatic ganache drip and the most show-stopping whole Oreo decoration in every single spectacularly individual and completely irresistible chocolate Oreo cake slice.
We hope it brings the same deeply joyful Oreo chocolate cake celebration and the same completely delighted table to your kitchen that it has always brought to ours. Make it, share it, and come back to tell us all about it. With all our love, Maria, Lucia, and Teresa.
