NON DAIRY MILK ALTERNATIVES YOU CAN USE AND TEXTURAL DIFFERENCES Oat milk is the best choice for a smoothie recipe like this one as it’s creamier and sweeter than soy milk. Thus oat milk is preferred for cereal and beverages. Maybe the best alternative is almond milk, as it’s got a nuttier flavor and thinner consistency. Coconut milk is the creamiest and thickest non dairy milk -it has a similar texture to dairy milk or heavy cream.
