Wash the pears and cut the pears into large chunks. You do not have to peel the pears.
Add the chunks of pears to the Instant Pot.
Add the rest of the ingredients into the Instant Pot on top of the pears. Mix to combine the ingredients.
Set the cooking time to 15 minutes on high pressure. After 15 minutes, allow the Instant Pot to natural release for 10 minutes. Quick release any remaining pressure.
With an immersion blender, blend the pears until it is the consistency of applesauce. Allow the pear butter to cool slightly before serving.
The mixture will continue to thicken as it cools. If you would like the pear butter thicker, set the Instant Pot to "saute" and cook for 5 minutes or until thick enough.
