1 ¾ tsp baking powder
-
1 tsp baking soda
-
½ tsp salt
-
1 ¾ cups granulated sugar
-
2 large eggs
-
½ cup neutral oil (like canola or sunflower)
-
1 cup buttermilk, room temperature
-
1 tsp vanilla extract
-
¾ cup hot coffee (or hot water)
-
1 cup crushed Oreo cookies (without cream filling)
Fluffy Vanilla Cream Filling & Frosting
-
2 cups cold heavy cream
-
8 oz (225 g) cream cheese, room temperature
-
¾ cup powdered sugar

2 tsp vanilla extract or paste
Dark Chocolate Ganache Drip
-
1 cup semi-sweet chocolate chips

🧁 Instructions
1. Bake the Cake
-
Preheat oven to 350°F (175°C). Grease and line three 6-inch cake pans.
-
In a large bowl, whisk together the flour, cocoa, baking powder, baking soda, salt, sugar, and Oreo crumbs.
-
In another bowl, whisk eggs, oil, buttermilk, and vanilla. Pour into the dry ingredients and mix until combined.
-
Slowly stream in the hot coffee. Batter will be thin.
-
Divide evenly between pans and bake for 20–23 minutes, or until a toothpick comes out clean.
-
Cool completely, then level the tops if needed.
2. Make the Frosting
-
Beat cream cheese and powdered sugar until smooth.
-
Slowly pour in cold heavy cream and vanilla while beating.
-
Whip until stiff peaks form. Chill until ready to use.
3. Prepare the Ganache
-
Heat heavy cream until simmering. Pour over chocolate chips in a bowl.
-
Let sit for 1 minute, then stir until smooth.
-
Let cool until the texture is like runny honey.
🎂 Assembly
-
Place one cake layer on a serving board. Spread ¾ cup of cream evenly.
-
Repeat for all layers. Lightly press extra Oreo crumbs around the edge for a “naked cake” look.
-
Chill assembled cake for 15 minutes.
-
Spoon ganache drip around the edge and pour a little in the center.
-
Pipe 8–10 rosettes on top with leftover cream. Add whole Oreos upright.
-
Dust with powdered sugar and scatter extra cookie crumbs around the base.
🧡 Pro Tips:
-
For sharp edges, use an offset spatula and chill between layers.
-
Use Dutch cocoa for a deeper flavor and color.
-
Add a few drops of espresso to the batter for even richer chocolate taste.
