These are the two most important ingredients in baking:

Milk

It’s pretty easy to replace milk all you need is to use soy or almond milk. They always taste the same in baking anyway. I tend to use almond milk because it’s healthier.

Butter

Believe it or not there is a dairy-free option for butter. I always use “Olivani Spread Lite”. It tastes the exact same and is delicious on toast as well.
