Grind cookies into crumbs in any way convenient for you. Add melted butter to the liver and mix well.
Put the mass in a detachable form covered with parchment, flatten and tamp. Refrigerate for 20 minutes.
Beat cottage cheese with a blender or rub through a sieve. Beat eggs with a whisk with sugar.
Pour the eggs into the cottage cheese, add sour cream, starch, vanilla and mix until smooth. Beating is not necessary.
Pour the curd mass onto the base, smooth and bake at 180 degrees for 40-60 minutes.
Cool the cheesecake completely, put in the refrigerator for 1 hour and only then remove the form. Bon Appetit!
