Place all of the ingredients into your Instant Pot and lock the lid into place, making sure the nozzle is in the sealing position.
Use the Manual or Pressure Cook setting and set the timer for 3 minutes. Use the natural release method when the timer is up.
When all of the pressure is out of the pot, take off the lid and allow to cool for about 10 – 15 minutes, and then transfer the mixture to your blender and blend until super creamy and smooth, about 2 full minutes. You may have to blend this in batches.
