5 small sour cream;
250 g powdered sugar;
4 boxes biscuits;
2 boxes of raspberry;
400 ml cream.
Mix the sour cream with the powdered sugar. In rectangular mold arrange 2 boxes of biscuits, then brush with half the mixture with the sour cream and finally sprinkle with raspberries. After that, repeat the same procedure.
When you are finished with it, brush with cream and would definitely put the cake in the refrigerator to cool.
Of course, you should not be surprised if virtually everyone will try and ask your recipe.
