Ingredients
1 box (15.25-ounce) chocolate or white cake mix
1 cup buttermilk, at room temperature
1/2 cup unsalted butter, melted and slightly cooled
3 large eggs, at room temperature
1 teaspoon vanilla extract
About 20 whole Oreo cookies, crushed into crumbs and small chunks
1 box (3.4-ounce) instant vanilla pudding mix (optional)
1/4 cup unsweetened cocoa powder (optional)
8 ounces full-fat block cream cheese, softened
1/2 cup unsalted butter, softened
3 to 4 cups powdered sugar, sifted
1 teaspoon vanilla extract
About 12 whole Oreo cookies, crushed
Instructions
1-Bake the cake: Preheat oven to 350°F and grease a 9×13-inch pan. Whisk together cake mix, buttermilk, melted butter, eggs, and vanilla until smooth; fold in crushed Oreos. Spread batter evenly in pan and bake for 25 to 30 minutes until a toothpick comes out clean. Let cool completely.
2-Whip up the cream cheese Oreo frosting: Beat softened cream cheese and butter until smooth and creamy. Gradually beat in powdered sugar, then add vanilla. Once light and fluffy, fold in crushed Oreos.
3-Frost and decorate: Spread frosting over completely cooled cake in a thick, even layer. Press mini Oreos on top and dust with cocoa powder if desired. Refrigerate for about 30 minutes to set before slicing and serving.

🧊 Always use full-fat block cream cheese and real butter for the frosting — low-fat or tub-style cream cheese has more moisture and will make the frosting runny.
⏰ Let the cake cool completely before frosting; spreading frosting on a warm cake will cause it to melt into a soupy mess.
❄️ This cake tastes even better after a night in the fridge — the cookies-and-cream flavor deepens, making it a perfect make-ahead dessert.
