• Heat your oven to 325°F. Spray a 9-inch round pan with non-stick spray. Put some parchment paper on the bottom.
• Crush the Oreo cookies until they look like fine crumbs.
• Mix the crushed Oreos and melted butter in a bowl.
• Push this mix into the bottom of the pan. Bake for 10 minutes, then let it cool.

Chocolate Cheesecake

• Put chocolate chips in a bowl.
• Heat up 1/2 cup of the whipping cream until it's warm, then pour it over the chocolate chips. Wait 5 minutes.
• Stir until it's smooth.
• In a big bowl, use a hand mixer to make the cream cheese smooth.
• Add sugar and cocoa powder. Mix well.
• Add the eggs one at a time, then add the other half of the whipping cream. Mix well. Now add in the melted chocolate.
• Add vanilla and mix one more time.
• Pour this over the crust in the pan.
• Bake for 70 minutes. Put another pan under it to catch any drips. It’s done when the edges are firm but the middle wiggles a bit. Let it cool, then put it in the fridge for 4 hours.

Ganache

• Heat 3/4 cup of whipping cream until warm. Pour it over chocolate chips and wait 5 minutes. Mix until smooth. Let it cool.

Toppings

• Take the cold cheesecake out and spread the chocolate sauce over the top.
• In another bowl, put all the stuff for the whipped cream except the mini chips. Beat until it's thick.
• Put the thick cream in the piping bag.
• Use the piping bag to put little puffs of cream around the edge of the cheesecake. Throw mini chocolate chips on top.
• Let chill for at least 4 hours, then serve and enjoy!
