In a medium bowl, mash the banana until no large chunks remain.
Add the oats, plant milk, mango, coconut milk, hemp seeds (if using), flax, vanilla, and salt and stir until combined.
Divide equally into two or three jars (I used lidded jars from Dollar Tree that hold about 13oz). Cover and refrigerate at least 4 hours or overnight.
The next morning, add the toasted coconut and additional mango to serve. No need to warm it up. It's delicious eaten cold.
Notes
If I’m using frozen mango chunks, I like to dice large pieces into smaller (½”) chunks while the mango is still frozen. To thaw, I measure out the amount needed for both parts of the recipe and place it in a wire mesh strainer. Run hot water over the mango pieces for 15-20 seconds. Ta da! Thawed mango!
To toast shredded coconut: Toast the coconut in a small skillet over medium-low heat for around 3 to 5 minutes, stirring frequently, until it's lightly browned and fragrant. Immediately pour it into a heat-safe bowl to cool. Store any unused coconut in an airtight container.
