Grease a 9-inch springform pan with cooking spray. Wrap the outside of the pan in aluminum foil and set aside.
In a large mixing bowl, combine the cinnamon roll crumbs, melted butter, and granulated sugar. Mix well until the crumbs are coated in the butter mixture.
Press the cinnamon roll mixture into the bottom of the prepared springform pan. Set aside.
In a separate mixing bowl, beat the cream cheese and granulated sugar until smooth and creamy. Add the eggs, one at a time, mixing well after each addition.
Add the flour, brewed coffee, and vanilla extract to the cream cheese mixture. Mix well.
Pour the cheesecake batter into the prepared crust. Smooth the top with a spatula.
Bake the cheesecake for 50-60 minutes, or until the edges are set and the center is slightly jiggly.
Remove the cheesecake from the oven and let it cool to room temperature.
While the cheesecake is cooling, prepare the peanut butter cup topping. Melt the chocolate chips in the microwave or on a double boiler until smooth. Add the peanut butter, melted butter, and confectioner's sugar to the chocolate mixture and stir well.
Pour the peanut butter cup topping over the cooled cheesecake. Spread it evenly with a spatula.
Chill the cheesecake in the refrigerator for at least 2 hours, or overnight if possible.
