In a medium bowl, whisk the eggs, vanilla, monk fruit powder, and coconut cream until combined.
Divide the mixture evenly among 4 (6-ounce) ramekins, filling them until ¾ full. Cover with foil. Pour 1½ cups water into the Instant Pot bowl and set a steamer rack or trivet in the bottom. Place three ramekins on the rack, and one on top of the three, in the center.
Secure the lid on the Instant Pot and lock it in place. Move the vent knob to the sealed position.
Select “Manual” and cook on high pressure for 9 minutes. Once the cooking time is up, carefully move the vent knob to “Venting” to quickly release the pressure.
The ramekins will be hot and slippery, so wear oven mitts or use a towel to remove them from the Instant Pot.
Cool to room temperature (about 1 hour), then place in the fridge to chill for at least 2 hours.
Just before serving, garnish with a dash of fresh ground nutmeg if desired.
