Begin by draining the canned corn (no need to rinse).
In a small bowl of the non-dairy milk, whisk in the flour until nearly all clumps dissolve.
Add all of the ingredients to the Instant Pot. With a spatula, stir to combine lightly.
Close the lid to the Instant Pot and set the valve to sealing.
Pressure cook on HIGH pressure for 3 minutes.
Once the timer goes off, quick release the steam until the pin drops, then open the lid.
Set the Instant Pot to the Sauté function. Using the spatula, stir the creamed corn until is reduces and thickens, about 3-5 minutes.
Taste and adjust salt and pepper as necessary.
Remove from Instant Pot and cool, then serve and enjoy!
