Preheat oven to 350°F. In the bowl of a food processor, combine the graham crackers and 2 tablespoons sugar. Process until finely crushed. Add the melted butter and pulse until well mixed.
Press the mixture firmly into the bottom and sides of a 9-inch pie plate. Bake for 8 minutes. Cool while preparing the filling.
To prepare the lemon filling:
In a medium bowl beat the sour cream until smooth with an electric mixer. With the mixer on low, slowly add the sweetened condensed milk and blend until combined. Add the egg yolks, lemon juice and zest. Pour the filling into the prepared crust and bake for 15-18 minutes or until the filling is set, but still jiggles a little in the middle. Cool on a wire rack to room temperature then refrigerate until ready to add the topping.
To prepare the topping:
Beat the cream cheese until smooth using an electric mixer. Slowly add the whipping cream and beat until combined. Add the powdered sugar and vanilla. Beat on medium-high until soft, but stiff peaks form. Mound the topping onto the pie using an ice cream scoop or pipe all over in a pattern as desired. Top with fresh lemon zest, sliced lemon and chocolate curls if desired.
To prepare chocolate curls:
Melt 2 ounce of white chocolate according to package directions. Spread on the back of a baking pan and refrigerate until set, about 3-4 minutes. Using a sharp spatula, create little curls. If the chocolate breaks into shards, allow it to sit at room temperature another minute or two until slightly softer. If the chocolate does not curl, pop it back in the refrigerator for a few minutes more. Curls may be made ahead and frozen until needed.
