Oh No!
We need that recipe!
My Mom made a peanut butter cake when I was a kid - once - it was great but she never made another :>(
This peanut butter take is getting Proustian! I’ve never had one and I’m starting to long for one.
My cooking idol, Nigella Lawson, has one on her cooking site:
www.nigella.com/recipes/view/peanut-butter-cake-845
The measurements are metric but she has an excellent conversion chart on the same page. And “cornflour” is cornstarch.
