Chocolate oreo cheesecake

Method :
1. Melt the butter and mix together to the crushed oreo cookies. Press the mixture into the cake tin base, baked for 10 mins and cool it then chill for later use.
2. Heat up the whipping cream and add in the chopped chocolate and stir till mix well and smooth.
3. Preheat the oven to 160°C. Pour some water to the base of the baking tray to create a water-bath. Wrap the base of the cake pan with aluminum foil to protect the water from sipping in.
4. In a mixing bowl, beat the cream cheese and sugar till fluffy. Add the eggs one at a time and beat again till combined.
5. Add chocolate mixture and stir well. Lastly, sift in the cocoa powder and cake flour and combine till mixture is smooth and add in oreo cookies.
6. Pour the batter into the prepared cake pan with the cookie base. Bake in the oven for 45 to 50 minutes (I baked the round cake for 35 mins and cupcakes for 15 mins). Making sure not to over bake, the center of the cake should still be a little "wobbly" when done.
7. Remove from oven and let cool for awhile.
8. Boil the chocolate, whipping cream and butter until mix well and smooth.
9. Pour onto the cake and let it cool completely before refrigerating. Chill for at least 4 to 6 hrs before serving
