Friendship cake

Add soda to the kefir.

Then add eggs, jam and mix everything well.

Then add flour (if you use liquid jam, add more flour, if thick – add less) and mix the dough. Its consistency should be thicker than dough for pancakes. Grease the pan with butter, place the dough and bake in the oven at 325-350F for an hour. Check the readiness with a match. While cooking, don’t slam the oven doors, otherwise the cake will lower. Sprinkle the cooked cake with sugar powder.
