I accidently bought the 5.1 oz of instant vanilla pudding when I normally get the 3.9 or 4.1 oz. What can I adjust to make it work? I weighed it out and the mix it actually only came to 4 oz. So that also confused me... help! Please and thank you!

I did this too but since I have a food scale so just measured out the regular 3.4 oz amount and will save the rest for another cake or less servings of prepared pudding....
