GINGER CHEESECAKE BARS

Steps:

• Preheat oven to 350 degrees. Coat a 9-by-13-inch rimmed baking sheet with cooking spray; set aside. Place gingersnaps in a food processor; pulse to a powder. Transfer to a small bowl, and stir in butter until well combined. Press gingersnap mixture evenly into bottom of prepared baking sheet. Bake crust until firm, about 12 minutes. Let cool completely.
• Meanwhile, put cream cheese in the bowl of an electric mixer fitted with the paddle attachment; mix on medium speed until softened. Mix in sugar, egg, egg yolk, sour cream, and vanilla until well combined. Mix in crystallized ginger.
• Pour the cream cheese mixture onto crust, and spread evenly with a rubber spatula. Bake, rotating sheet halfway through, until filling has puffed and feels slightly firm to the touch (do not let brown), 20 to 25 minutes. Let cool completely on a wire rack. Refrigerate, covered with plastic wrap, until set,about 1 hour. To serve, cut into bars.
