I used an an almagamation of recipes from True North Kitchen (here) and Alice Medrich (here).
My cake contains olive oil (Medrich) and buttermilk (TNK). I split the batter 55/45 between the vanilla and the chocolate. If anything, I might try a 60/40 split next attempt, as I had a little extra of the chocolate batter at the end.
I made a half-recipe (TNK volumes) in an 8”x4” Fat Daddio loaf pan, baking it for 60 minutes at 325.
The moisture level, flavor and texture came out great, and I’m looking forward to tomorrow’s taste, as I suspect a good thing will be yet improved overnight.
