How much mayonnaise?

[Mistygirl]

I'm looking for conversion charts , I'm trying to put mayonnaise in my chocolate chip cake .last time I did it it came out amazingly most, it was so good, but I can't remember how much Mayo I use instead of eggs and oil .

Welcome to the forum! I've not tried this myself, but when I've read about people doing it they substituted mayonnaise for oil using a 1:1 ratio. I didn't think the substitution applied for eggs though, are you sure you omitted them last time?
