My mother and I used to whip this up and make all kinds of things: bread, cinnamon rolls, bread sticks, roll little balls of dough in cinnamon and sugar and fry them, roll little balls in melted butter then coat with cinnamon and sugar and put them in a bundt pan for coffee cake....anything we could think of. (and I mean we'd make all those things out of one recipe - that's why it's called Big Batch Buns!!)
We'd get one thing baking in the oven and then ask, "what else should we make?" We'd spend all day baking. Ahhh, great memories.
I honestly have to say; servings, prep and baking time are a total guess. It depends what you make and how many things you make. :-)
