1. Put oats in blender and grind to a fine meal.
2. Add all other ingredients, and blend until very smooth.
3. To use immediately, measure 1:1 for nondairy milk in recipes.
4. For later use, refrigerate and shake vigorously just before using.
Works well for baking and gravies; haven't tried it yet in coffee.
Source of recipe: I came up with this when I needed soymilk for a bread recipe, but was out; much to my surprise, it worked great!
