Place oats, water, mango, coconut oil, salt, and cardamom (if desired) in a pot.
Stir to combine and bring to a boil.
Reduce heat to the lowest setting and simmer for about 22 minutes, stirring well every 5 minutes.
The oatmeal is done when it still looks somewhat soupy as it will continue to thicken as it cools.
Remove from heat and stir in coconut sugar (add more to taste if desired) and vanilla extract.
Portion into bowls and top with fresh mango plus a drizzle of almond butter.
To store: Store leftovers in an air-tight container for up to 5 days.
To freeze: Portion into individual containers and freeze for up to 3 months.
