How to make
Boil the starches separately according to the instructions. Sugar is also according to them, but also according to your taste. Add 1 level top tablespoon of margarine.
The biscuits are dipped very briefly in hot milk mixed with water. If you hold them according to the description on the biscuit box, they will fall apart.
Arrange a row of biscuits in a small tray, spread the boiled starch on top. On the white biscuits - brown, on the chocolate - yellow.
Sprinkle the biscuit cake with some ground walnuts and chopped blueberries. Alternate biscuits, starch, walnuts, and blueberries until they run out. I arrange the biscuits first lengthwise, then widthwise, along one diagonal, and then along the other.
Finish off the starch by sprinkling it with walnuts and blueberries. The starch is 2 packets because I prefer more between the biscuits.
This very simple biscuit cake is very tasty.
