Amish Friendship Bread Batter is a cake starter and all the variations I’ve found on-line to make it more bready are too sickeningly sweet. Does anyone have suggestions on how to either use the batter to make a sourdough bread variant?

Thus far, I’ve used variations in on-line recipe catalogs for both bread loaves and biscuits that claim to result in “sourdough”. But the bread loave recipe took a full cup of sugar which made the bread more a dessert bread and the biscuits, while without sugar, were more like the cross between a croissant and a buttermilk biscuit without the flakiness or fluffiness of either.

Suggestions welcome!
