What did you cook or eat today (March 2022)?
I remember you are trying to avoid dairy, what kind of moisture did you use? I am just trying to figure out why the muffins were dry. I too would not like dry muffins. I use buttermilk but I am not sure if that's even something available to you, and also if you are avoiding dairy, that's out. Also oil or butter in the mix helps to keep the muffins moist. Did you use oil or butter? I also use egg in mine.
As far as the sweetness goes, I was just thinking that more natural sweeteners would be better than refined sugar, but 71g of sugar is a lot, yes.
Edited to add: this recipe for dairy free corn muffins. This one calls for sugar, but I think you could just cut the small amount used in half or sub with a lesser amount of honey. Also, this recipe author uses canned corn. I have read other recipes where people use canned creamed corn to help with moisture, but often that contains sugar. I suppose you could whir some corn and a touch of unsweetened almond milk in a blender to make your own? Just thinking...
