This is the ultimate Babka. I am Polish and have eaten Babka my whole life. This is the best and you use a bread machine. The yeast I use is Fleischmann's Active dry Yeast. I have used bulk granular yeast from a co-op. Both work the same. This is my grandmothers recipe which I adapted to bread machine. Babci(gram) was born in late 1800's in Poland. My Mom 85 yrs. old cannot tell the difference in taste or texture.

2 eggs beaten
