For crust, combine graham crackers, nuts, and melted butter. Press crumb mixture onto a 9-inch springform pan.
In a small sauce pan, combine the caramel and water. Melt the caramel on low heat. Set aside.
For filling, beat cream cheese, sugar, flour, and vanilla with an electric mixer till combined (don't over mix). Add eggs and egg yolks, beating on low till combined. Stir in milk.
Pour half filling into springform. Then pour melted caramel onto the filling, pour the remaining filling on top of the caramel.
Bake at 375 degrees for about 35 minutes or till center appears nearly set.
Cool on wire rack for 20 minutes. Loosen the crust from sides of pan and cool completely. Cover and chill overnight before serving.
