Has anyone figured out approximately how many cups the smaller size BC mixes make? I figured about
5 1/2 cups per mix for the 18 oz. mixes and was able to determine how many mixes I would need for almost any size cake using the Wilton chart for cups of batter needed for each size. I don't have any idea how many cups the new smaller size makes as I am just using up my inventory of 18 oz. mixes. I have to make several larger cakes this weekend and don't want a lot of batter leftover. Thanks for any help!

I don't use the boxes so I can't tell you for sure, but it would seem like if 15oz is 83% of 18oz, then it will make 83% of 5.5 cups, or 4.58 ish cups.
