directions
Preheat your oven to 350°F (175°C). Grease and line two 9-inch cake pans.
In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
In another bowl, mix the buttermilk, vegetable oil, eggs, and vanilla extract.
Add the wet ingredients to the dry mixture, stirring until combined. Then stir in the hot water and crushed Oreo cookies.
Divide the batter evenly between the prepared pans and bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean. Let the cakes cool completely.
For the buttercream, beat the softened butter until creamy. Gradually add powdered sugar and cocoa powder. Mix in the heavy cream and vanilla extract until smooth and fluffy. Fold in the chopped Ferrero Rocher.
Assemble the cake by spreading a generous layer of frosting between the cooled cake layers, then frost the top and sides.
Decorate with whole Ferrero Rocher chocolates and sprinkle crushed Oreos on top for a finished look.
