Babka is made of a type of dough called enriched dough that makes the pastry the delightfully fluffy baked good we all love. Doughnuts are often made with the same kind of dough. Babka can contain jelly and so do the traditional Sufganiyot (jelly doughnuts) that we eat on Hannukah. These babka sufganiyot are a delicious combination of the two pastries, with a blueberry and lemon filling that lightens up the fattiness from the frying oil.
