Spray the inside of a 9-inch springform pan lightly with oil and place a piece of parchment on the bottom. Wrap the pan with two sheets of aluminum foil to keep it watertight for the water bath.

Use a food processor to grind complete Oreo cookies (including their filling) into fine crumbs. Stir in the melted butter until combined. Firmly press the mixture into the springform pan's base and chill it while the filling's made.

Set your oven to 350°F. Beat cream cheese with sugar until smooth. Add peanut butter, cream, and vanilla, then stir until well blended. Beat eggs in one at a time without overmixing. Fold in the mini chocolate chips. Spread this filling evenly over your crust.

Put the springform pan into a larger dish, then add hot water to the dish so it comes a bit up the sides of the pan. Bake for about 55-70 minutes, or until the edges are firm but the middle jiggles just a little. If the top browns too much, loosely cover with foil. Let cool out of the water, then refrigerate for at least 5 hours or more.

Heat up the cream on medium heat until it starts to boil. Put half of the chocolate chips into a heat-safe bowl, then pour the hot cream over them and mix until they melt. Stir in the remaining chips until silky smooth. Let it cool enough to thicken but stay spreadable.

Carefully loosen and remove the pan's outer ring. Transfer cheesecake to a serving plate. Spread ganache across the top and let it drip over the sides (do it in two rounds if needed). Sprinkle chunks of Reese's and crushed nuts over the top. Keep chilled until serving.
