Other than another type of milk what liquid can be substituted for 1/2 cup milk in muffin recipe?
I use sour cream or creme fraiche in lieu of milk in baked goods.
I use almond mild, flavour is better than milk
almond milk sorry
If it's a food allergy, then Picnic's suggestion isn't possible.
It depends on the type of muffin. I've used both applesauce and home-boiled pumpkin (more watery than canned). Might add a spoon of oil, and less sweetner if needed. Corn based muffins, try a broth (not too salty)
Shredded zucchini (don't release juices inside) plus water also works.
