I'm going to be honest: I'm not vegan or, at least, not yet. I've, however, been thinking about reducing the amount of animal-derived food I consume. One place I have missed is coffee creamers. My wife and I (and everyone on planet earth) drink coffee constantly. So, I'm looking for some good vegan alternatives that can either be bought at the store or recipes that I can make at home.
All you need is Xanthan gum. It's a powdered thickening additive without any flavor or calories, and you can slowly blend it with any liquid to make it into a jelly-like syrup. I blend up soy milk, vanilla, sweetener, and sloooowly sprinkle the Xanthan gum powder in.
I'm not vegan or even vegetarian, not try to cut back diary generally. We have used Planet Oat oatmilk creamer for the last couple years and really like it. It is certified vegan for those that look for that. It has the right consistency to replace normal dairy creamers pretty well and tastes good. There's a variety of flavors if you go for that as well.
