Prepare 12 baking cups or panettone baking cups (I used 2 3/8 x 2 Inch ) or mini springform pan.
In a medium bowl, combine the graham cracker crumbs and melted butter. Stir until well combined.
Press evenly in the paper cups with shot glass, to make firm layer. Chill in the fridge whilst you do the rest!
Melt the chocolate in the microwave safe bowl on short bursts until fully melted – leave to cool slightly.
Whisk the Cream Cheese and Icing sugar and vanilla with an electric mixer until combined. Pour in the heavy cream and continue to mix until it is starting to thicken a lot like a Mousse does!
Pour 1/3 of mixture in a separate large bowl, and set aside.
Pour the melted chocolate in the remaining 2/3 of mixture and fold together until smooth, and then spread onto the cheesecake base. Leave it in the fridge to cool.
Add the peanut butter to the reserved mixture and mix it through until you get fine, smooth mixture. Spread evenly over chocolate cheesecake filling. Place it in the fridge.
Melt the chocolate and stir in heavy cream. Spoon chocolate ganache on top of each cheesecake. Sprinkle chopped peanuts and mini chocolate chips on top for garnish.
Store cheesecakes in refrigerator.
