Make a batter for the base from cookie crumbs, nuts and butter. Press on in a size 26 mold and chill it.
For the filling, mix the cream cheese, sour cream, bananas, flour and sugar in a large bowl. Stir in the eggs one by one, then mix in the nuts, cinnamon, nutmeg and flavor.
Pour the mixture into the prepared form and bake at 180 ° C for approx. 45 - 55 minutes. Let the cake cool for 2 hours and chill for at least 6 hours. Now the cheesecake can be decorated with the banana chips.
