Time for a new cake recipe again! This time we tried something entirely new, using poppy seeds to make this German poppy seed streusel cake.

We didn’t want to go for the prepared poppy seed filling you can buy in stores so we made it ourselves. Of course you can find the steps below as well.

The result turned out very beautiful as you can see and this cake is a beautiful addition to our recipe collection as well as every Sunday coffee table. Classic and never out of fashion.

In Germany, it is called Mohnkuchen: it is a combination of poppy seeds (Mohn) and cake (Kuchen).

Conclusion

Taste

This German poppy seed streusel cake is a perfect match of different textures. The cake base is firm and a bit crunchy while the poppy seeds filling is soft, moist and a little jelly-like. The top of the cake, the streusel, are very crunchy again.

The level of sweetness is lovely balanced throughout the cake. It is not too much and not too little and brought to perfection thanks to the powdered sugar on top.
