Line a 8″x8″ glass pan with foil, be sure to cover the sides, you are going to use this to lift the cheesecake out of the pan.
Combine the melted butter and gingersnap crumbs and press into the bottom of the pan. Cook for 10 minutes. Remove and allow to cool.
Reduce oven temperature to 325 degrees.
In the bowl of a stand mixer (or with a handheld mixer) beat cream cheese and sugar until smooth. Beat in eggs one at a time. Beat in eggnog, sour cream and nutmeg. Mix on medium speed until silky and smooth.
Pour mixture into cooled crust. Bake in preheated oven for 40 - 45 minutes or until center is set. Remove from oven and allow to cool at room temperature for 30 minutes. Chill in the refrigerator for 2 more hours before slicing.
