Kermakakku is a favorite of mine. Kermakakku is a traditional Finnish cake. It is slightly dense with a hint of cardamom and almond. Translated Kermakakku is Cream Cake. I have been missing my childhood food lately. Maybe turning 40 has something to do with this. I made the original Finnish sour cream cake a few weeks ago, then on Saturday I made this lemon blueberry version. Love at first bite!
The lemon juice added a hint of lemon and made the cake moist. I didn’t add a glaze to the top but a lemon glaze would make it even better! I will add a recipe for that at the bottom of the post.

If you do not have a sifter. You can use a small strainer or colander and lightly tap the sides. Works like a charm.


When the cake is done you will notice cracking on the top. Gently poke the cake with your finger, it should bounce back. You can also check the cake by poking it with a skewer or fork. If it come out clean it is finished.
