Thank you, and also to @Desert-Dan, @CaitlinM, and @fivealive!
I also found the Alice Medrich hot milk cake recipe I had saved ages ago, so I rabbit-holed a bit (of course, haha) on proportions.
KAF is the only oil cake, all the others use butter. Eggs to flour are pretty consistent except for the Medrich recipe, which uses both eggs and yolks. Milk was the most inconsistent: drastically lower in the Medrich recipe relative to all others.
Hmm. I think I will try a 1 egg version of the higher milk version first, and try Medrich another time.
@Nannybakes you will likely beat me to the punch on a trial, so I am staying tuned!
