I was today years old when I found out that adding mayonnaise to a chocolate cake recipe levels it up to an upper echelon type of moistness. On a recent TikTok bender, I happened upon the above video for a chocolate cake recipe that incorporates mayo into it.
As the home chef indicates in the clip, the mayonnaise adds "extra egg yolk and a very creamy texture."
Apparently this cake hack hearkens back to around World War II or the Depression, when cooks were forced to get creative with replacements in recipes due to ingredient scarcity, as cited by The Kitchn.
Though mayo in cake may incite an automatic "nah" on paper, the end result of the creamiest, most moist chocolate cake ever sounds enticing enough to try.
