Non-dairy milk alternatives are perfectly acceptable for use in a cornbread recipe. This plant based cornbread used unsweetened almond milk, but you are welcome to incorporate your non-dairy preference. Depending upon the type of cornbread you are making - savory, sweet, filled with herbs or veggies - you will need to consider the flavor profile of the non-dairy milk. Select a neutral-flavored option if you intend to showcase savory flavors, so as not to overpower any of the other flavors.
