Anyone found a good cake recipe for Domhain? (Experimental build)

Tried a few combinations, but can't seem to find any mixture of cake ingredients (flour, sweetener, toppings) that is actually worth the investment. I can still make a profit on it, but the margin is so small any interruption in supply puts me in the red.

I know the Orehearts and Ironbreakers have differing tastes (Orehearts like Vines, Ironbreakers like Brews for example), but neither seem terribly interested in desserts despite that one storybook quest.
