How to make
We start with the cake cream. Mix the sour cream with powdered sugar.
Separately grate the apples, add almost all the walnuts and cinnamon to them.
In a springform pan, we arrange the biscuits that we have previously soaked in milk. We put cream on top, then a row of apple filling.
Keep doing that until you run out of the products. The last row is finished off only with cream, decorate with grated walnuts, grated biscuits and chocolate.
Chill and serve the biscuit cake.
The biscuit cake with apples and walnuts is ready.
