InstructionsFor the cheesecake
Preheat the oven to 350 degrees. In a large mixing bowl, cream together the cream cheese and the sugar. Add the flour, eggs, vanilla and cream and mix together till blended. Stir in the Oreo pieces.
In a 9 inch springboard pan lined with parchment paper and sprayed with cooking spray, pour the batter.
Bake for 25- 30 minutes or until the center is set.
Remove from the oven and allow to cool on a cooling rack for 20 minutes and then, cover and place in the refrigerator while you make the chocolate cake layers.
Make the Chocolate cake layers
Preheat the oven to 350 degrees and spray two 9 inch round cake pans with cooking spray.
In a large mixing bowl, stir together sugar, flour, cocoa, powder, soda, and salt.
Add the eggs, buttermilk, oil, and vanilla and mix until blended
Add the coffee and mix until blended
Pour batter evenly into the two pans and bake for 25-30 minutes or until the center of the cakes are set.
Remove from the oven and allow to cool on a cooling rack for 10 minutes before carefully removing from the pans. Allow to completely cool on the rack.
Using a long serrated knife, remove the top portion of each cake so they are level.
Make the frosting
Coarsely chop the white chocolate squares and melt them in the microwave in a small bowl for a minute.
In a large mixing bowl, cream the cream cheese and butter together. Add the vanilla and white chocolate and mix until blended. Add the powdered sugar one cup at a time, mixing until blended each time.
Assemble the cake
On a cake plate, place the first layer of chocolate cake, removing the cheesecake from the refrigerator, remove it carefully from the springboard pan, and add on top of the chocolate layer. Finally, add the top chocolate layer.
Frost the cake and garnish as desired. ( I frosted the cake with a crumb layer first and then the top layer. I then created five rosettes with a large Wilton tip. and placed a half Oreo in each. I broke up several Oreos and placed them in the center, and used chocolate cookie crumbs to lightly garnish the sides)
