Jiffy Corn Muffin Mix - Baking as Cornbread
I have several boxes of Jiffy Corn Muffin Mix and want to make some cornbread to accompany tonight's dinner. But I have no idea how many boxes to use to make a 9X13 pan of cornbread.
Each box is enough mix for an 8X8 pan - so should I use two or three boxes? (Yeah, math is not my strong point today!)
