Combine the brown sugar with the cocoa powder and whisk together until there are no lumps.
Melt the vegan butter in a small saucepan over medium heat.
Add the brown sugar and cocoa powder mix, almond milk and a pinch of salt to the melted vegan butter. Whisk until smooth.
Bring the mixture up to a gentle bubble, whisking frequently, and then continue to cook and whisk for another minute.
Remove from the heat, and whisk in the vanilla extract. Let the sauce rest for five minutes before serving.
