OK, the verdict is in.
Her first words were “it’s very rich!” I didn’t really find it to be, though obviously a bit moreso with the frosting.
The cake itself definitely isn’t quite right somehow. I think maybe a bit too much baking soda & powder, or maybe a tad too little sugar (I had reduced the original recipe’s sugar a bit).
It’s also pretty dry, and crumbles a lot when trying to cut it. Very messy.
All that being said however, as long as you get a bite with a bit of frosting with it, it’s really very tasty as the sweet balances out the slight saltiness of the cake.
So, whenever I try cake again, I’m going to cut the baking soda/powder back to only 1sp. each, and increase the sugar maybe to 3/4 cup. Might also use white sugar instead of brown. Probably also ditch the added salt.
If anyone else experiments and gets a better result, please do share!
