How many mini cupcakes will a box of Jiffy make? And how long do I cook them for?

I know that a box of Jiffy corn or apple-cinnamon muffins, for example, will make about 6 regular muffins. But how many mini muffins will it make? Also, what will the new cooking time be, and will I have to change the oven temperature? Thanks!|||Probably 12-18 mini muffins - depending on the size. I'd start checking them after 5 or 6 min - at the same temp
