Instructions

First, coat a 9-inch springform pan with cooking spray and line the bottom with parchment paper. Wrap the pan with two layers of aluminum foil, bringing the foil up the sides of the pan. Make sure the foil is tight and secure so no water gets in during the baking in the water bath!

To make the Oreo crust:

1. Finely ground whole Oreo cookies with the filling to get fine crumbs, using a food processor.  Combine the crumbs with melted butter and stir until evenly moistened.
2. Press the mixture into the bottom of the springform pan and set it in the fridge to firm while preparing the filling.

To make the cheesecake filling:

1. Preheat the oven to 350 F.
2. Beat softened cream cheese with sugar until smooth.
3. Mix in peanut butter, heavy cream, and vanilla.
4. Add eggs one at a time beating after each addition just to combine, do not over-mix it.
5. Stir in chocolate chips and spread the mixture over a chilled crust. Smooth the top and place the springform pan in a roasting pan. Pour hot water into a roasting pan (about a quarter of the way).
6. Bake for 55-70 minutes, until the cheesecake is set around the edges and slightly loose in the center. Tent the top of the springform pan with aluminum foil if starts browning.
7. Remove the cheesecake from the water bath and set it on a cooling rack to cool. Remove aluminum foil and refrigerate (at least 5 hours or overnight).

Milk Chocolate Ganache:

1. When the cake is completely cooled run a thin knife around the edge and release the ring of the springform pan, then transfer the cake to a serving plate.
2. On medium heat bring heavy cream to a boil. Place half of the milk chocolate chips (or chopped chocolate) in a heatproof bowl and pour the cream over the chocolate. Stir until the chocolate is melted completely. Add the remaining chocolate and stir until it’s melted and smooth. Set aside to cool. The ganache should be pourable but not too thin.
3. Spread the ganache on top all over to the edges and let it drip down the sides. I suggest you do this in two layers to avoid the ganache running down too much and cover the whole edges of the cake. Also if the ganache won’t drip enough you can slightly reheat the second batch and drizzle it with the spoon. Let the ganache set slightly then sprinkle with chopped peanuts and pile with coarsely chopped Reese’s.
4. Set in the fridge until ready to serve.
