Chill in the freezer for 15 minutes. Filling: In a large bowl, beat the cottage cheese, sugar, and eggs until smooth. Add the vanilla and light cream and continue to beat until smooth and fairly thick. Gently fold in the crushed peaches. Pour the mixture into the chilled pan. Place the springform pan inside of a larger pan containing 3 cm of water and bake in a preheated 325 degree oven for 1- half hours. Transfer the cake to a wire rack and allow to cool for 30 minutes. Topping: In a small mixing bowl, beat the sour cream and sugar until smooth. Spread the mixture evenly over the top of the cake and bake in a preheated 350 degree oven for 5 minutes. Transfer the cake to a wire rack and let cool completely. Remove the sides of the springform pan and decorate the top of the cake with the sliced peaches. Refrigerate overnight.
