Step-by-step instructions
- Preheat your oven to 180°C (350°F) and prepare two round cake pans by greasing and flouring them.
- In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt to combine.
- In a large mixing bowl, cream the softened unsalted butter with granulated and brown sugars until the mixture is light and fluffy.
- Beat in the eggs, one at a time, while stirring in the vanilla extract.
- Gradually alternate adding the dry mixture and buttermilk into the creamed mixture; mix gently until combined.
- Slowly stir in the hot water until the batter is smooth and well-combined.
- Evenly divide the batter between the prepared cake pans.
- Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.
- Allow the cakes to cool completely in their pans while you prepare the frosting.
- To make the frosting, beat softened butter and icing sugar until fluffy. Stir in vanilla and fold in the crushed Oreo cookies. Adjust with a splash of milk if the consistency isn’t spreadable.
- Once cooled, place one cake layer on a serving plate and spread a layer of Oreo frosting on top. Add the second layer and frost the entire cake.
- Decorate the top with Ferrero Rocher chocolates and press crushed Oreos onto the sides of the cake.
- Refrigerate the cake for at least 30 minutes to set the frosting before slicing and serving.

This cake is a hit on its own, but you can elevate the experience by serving it with a scoop of vanilla ice cream or a dollop of fresh whipped cream. A side of hot chocolate or a strong cup of coffee also pairs beautifully, enhancing the rich flavors. For added flair, consider drizzling some chocolate syrup over the slices when serving.
