• Preheat oven to 350℉. Spray a 9 inch springform pan with 2 ¾ inch sides with non-stick cooking spray.

Crust

• Add cookie crumbs, pecans and ginger to the bowl of a food processor and pulse until nuts are finely ground.
• Add melted butter and pulse until crumbs come together.
• Press crumb mixture on bottom and 2 inches up sides of springform pan.  Bake crust for approximately 10 minutes or until set and lightly browned.  Cool completely on a wire rack.
• Keep oven preheated to 350 degrees.

Filling

• In the bowl of an electric mixer blend cream cheese and sugar for about 2 minutes or until light and fluffy.  Add pumpkin and mix until well incorporated.  Add eggs, 1 at a time, blending on low speed after each addition, scraping down bowl occasionally.  Add the flour, spices and salt and beat to blend.  Beat in vanilla.
• Pour filling into cooled crust, filling to just above top of crust.
• Bake until edges begin to crack and filling is just set in the centre.  Filling should move just slightly in the center when pan is gently shaken.  This should take about 1 hour and 20 minutes.  Cool for one hour on wire cooling rack.  Cut around edges to loosen cake and cool in the cake pan over night.

Marshmallow Topping

• Combine marshmellows and milk in a large saucepan and heat over low heat until marshmellows are melted.  Remove from heat and stir in vanilla and salt.  Cool mixture to room temperature, stirring occasionally.  Gently fold sour cream into marshmellow mixture.  Pour topping over cheesecake leaving a 1/2 inch border around edges.  Chill for at least 1 hour to set topping.  If there are any cracks in the cheesecake, this topping will cover them up!
• Remove springform ring when ready to serve
