Beat the eggs until frothy. Add sugar and vanilla sugar and continue to beat until frothy. Then add the margarine and continue to beat until smooth. Gradually add the remaining ingredients and pour the dough into a large loaf pan.
Bake at 180 ° C top / bottom heat for 40 - 50 minutes. Use the chopstick sample to test whether the cake is properly baked through.
