This lemon cake with blueberries and sour cream is a potluck must have. Kermakakku is a traditional Finnish cake. It is slightly dense with a hint of cardamom and almond. Translated Kermakakku is Cream Cake. 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!

tips and tricks for kermakakku

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.

Using a butter knife. Gently slide the knife between the cake and the pan, pulling away from the pan. Do this all the way around the pan and in the center. This will loosen the cooled cake and make it easier to get the cake out.
