Amaretto Cheesecake

Toss cookies, sugar and butter in a food processor and blend. Crumbs should stick together. If they don't, add a little more melted butter. Pack into bottom and up the sides of a springform pan Place cream cheese, sugar, eggs and liqueur in a food processor and blend until smooth. Pour into the prepared crust. Bake for 1 hour at 350 degrees ... or until filling is firm and top is golden brown. When cake is cooled you can add topping. Combine sour cream, sugar and liqueur in a food processor, and blend. Pour on cake. Chill for about an hour so it sets up nice. Put the cake on your serving plate and remove the springform pan. If you want to be really decadent, pour a can of prepared cherry pie filling over the whole thing just before serving.
