Finely grind whole Oreo cookies (with filling) into crumbs using a food processor. Combine crumbs with melted butter, mix until evenly moistened. Press mixture into the bottom of the springform pan and refrigerate to firm while preparing the filling.

Preheat oven to 350°F. Beat softened cream cheese and sugar until smooth. Mix in peanut butter, heavy cream, and vanilla extract. Add eggs one at a time, beating lightly after each addition. Stir in chocolate chips. Spread mixture over the chilled crust and smooth the top.

Place the springform pan in a roasting pan and pour hot water into the roasting pan (about a quarter full). Bake for 55-70 minutes until the edges are set and the center is slightly loose. If the top browns, tent the springform pan with aluminum foil. Remove from water bath and cool on a rack, then refrigerate for at least 5 hours or overnight.

Bring heavy cream to a boil over medium heat. Place half the milk chocolate chips in a heatproof bowl and pour the hot cream over the chocolate. Stir until melted, then stir in remaining chocolate until smooth. Let cool until thickened but pourable.

Run a thin knife around the edge of the cheesecake and release the springform pan ring. Transfer cheesecake to a serving plate. Spread ganache over the top, allowing it to drip down the sides. For better control, pour ganache in two layers, reheating slightly if needed. Garnish with chopped Reese’s cups and crushed peanuts. Refrigerate until ready to serve.
