Lemon cake with chia seeds and kefir. A cake that is moist, airy, fragrant and is the best way to utilize the lemons that are in abundance this season.

What makes this lemon cake moist and airy?
This lemon cake with chia seeds and kefir is as moist and airy as you want. But what makes this lemon cake so special?
- In this cake kefir was used instead of milk. Kefir makes the cake more airy due to its bacteria.
- According to a Japan cake recipe a tablespoon of sunflower oil adds extra moisture to a cake. I trusted the recipe, and it did not let me down.
- Also, an important role for making a cake fluffy plays how fluffy the butter will be with the sugar. This is because the longer we beat these two ingredients, the more air is trapped in them.
- Last but not least, the addition of a syrup in the cake made it extra moist. The syrup is made very simply by mixing lemon juice with powdered sugar. Be careful, the syrup should be added to the cake ten minutes after removing the cake from the oven.
May I not add the syrup?
If you don’t want to add lemon syrup of course and you can do it. However, keep in mind that then your cake will not be so fragrant and moist. Also, if you are afraid that it will become too “lemon”, you can use orange juice for the syrup instead of lemon juice. Or both!

Is it ok to skip chia seeds?
If you want you may skip chia seeds and not adding them to the mixture. But adding them to the cake mixture has only positive side effects. Why? Because chia seeds contain fiber, minerals, vitamins, omega-3 fatty acids, potassium and calcium. They also have a neutral taste and therefore will not alter the taste of the cake at all.
May I substitute kefir?
If you do not have kefir you can replace it with sour milk. If you still do not have sour milk then you can do the following. Add to a corresponding amount of milk half a tablespoon of white vinegar or lemon juice. Set aside for 5 minutes and it is ready.
