Pour the coconut milk, vanilla extract, and salt into the Instant Pot. Add the rinsed rice, then pour the maple syrup on top. Stir.
Cover the Instant Pot and turn the vent to Sealing. Cook on Manual high pressure for 18 minutes. Let the pressure release naturally for 10 minutes, then release the remaining pressure and open the pot.
Serve sprinkled with cinnamon and fruit. This pudding can be enjoyed warm or cold, but I prefer it warm. For the best texture, warm up the leftovers with a little extra coconut milk.
