Line the sides of the cooking ring, here with a diameter of 20 centimeters, with plastic wrap. Place the ring on a plate and pour in the cookie crumbs. Press down firmly with your hands or a glass to form an even layer. Refrigerate.
Put the cottage cheese in a bowl, using a sufficiently moist and not too lumpy variety. Add condensed milk.

Mix with a spoon.
Spread a couple of tablespoons of the cottage cheese mixture over the cookie crust. Arrange pieces of banana on top.
