Heat a small pot over medium heat.

Melt the vegan butter.

Add in the oat flour and stir with a wooden spoon to create a light roux. The flour and butter should be fully incorporated. If the flour isn’t completely incorporated into the butter, it will react with the water in the next step and make lumpy gravy.

Add in water and vegetable bouillon.

Stir constantly while bringing to a boil.

As soon as it’s reached a boil, reduce heat to simmer.

Simmer for two minutes, stirring occasionally.

Add salt and pepper.

Serve hot.
