A great cake recipe for any occasion:
Heat butter, pour in oatmeal, let brown slightly, stir and cool.
Remove seeds from dates and cut into very small cubes.
Beat eggs with sugar, vanilla sugar and baking powder until creamy. Add dates and oatmeal and stir well. Form small heaps on a baking tray covered with parchment paper. Put the tray into the preheated oven (center, 175 degrees, 20 to 25 min).
Makes about 75 cookies.
