How to make
Preheat the oven to 360°F (180 °C). Beat the eggs until whitened and add the sugar and vanilla sugar.
While stirring constantly, add the slightly melted butter, milk and pre-sifted flour and baking powder.
As soon as it is a homogeneous mixture, mix in the poppy seeds and orange peels. Pour the cake batter into a greased cake pan or tray.
Put it to bake for 40 minutes.
