• Start by lining the bottom of a 7.5in springform pan with parchment paper and spray pan with baking spray or some other type of non-stick spray.
• Next, use a food processor and grind up the Oreos into small crumbs. Once done, mix in the melted butter.
• Then, take and spread the crust mixture into the springform pan and up the sides to completely cover it. 
• After that's finished, take and place it into the freezer while you start to make the cheesecake mixture. 
• You're going to want to use a standing mixer for this next step. Start to beat together the cream cheese and sugar until combined and smooth.
• Next, add in and beat in the vanilla, flour, nutella, and heavy cream until it's all combined very well.  
• Grab your eggs and beat them in one at a time. 
• After that, it's time to pour your cheesecake mixture into the crust.
• Add in 1 cup of water into the Instant Pot and then place the trivet inside. 
• Cover the cheesecake springform pan with foil and carefully place the cheesecake down into the Instant Pot.
• Next, take and lock the lid in place. Select high presser and set the timer for 50 minutes. 
• When it beeps and is done, allow for a natural release. Then turn off and allow the cheesecake to cool for 1 hour.
• Carefully remove the lid from the pot and make certain that you place it onto the counter and allow it to cool completely.
• Place your cheesecake in the fridge overnight.

Chocolate Ganache

• Grab a medium pot and heat-safe bowl and begin to heat the cream up in the pot until it's hot.
• When it's ready, add the chocolate chips into the bowl and pour the hot heavy cream over the chocolate chips to start the melting process.
• Start the timer and allow to sit for 2 minutes before whisking it all until smooth.
• Once it's smooth, you're going to take and pour the ganache over the top of the cake and spread it out evenly.

Chocolate Whipped Cream

• The time has come to make the homemade whipped cream! Start by grabbing a medium bowl and hand mixer and add in all ingredients except the sprinkles and beat until stiff peaks form.
• Then, take it all and put it into the piping bag.
• Pipe along the edges of the cheesecake and be generous...
• Once done, take and sprinkle chocolate sprinkles all over!
• Serve and enjoy!
