Place steamer basket in the Instant Pot and add 1 cup water.
Arrange scrubbed potatoes on their ends inside the steamer basket. Cover the Instant Pot and place vent on lid to "Sealed". Set the Instant Pot on "Steam" program and set time for 10 minutes.
When finished cooking, don't open the lid. Allow pressure to reduce naturally, about 25 minutes.
Remove lid and remove the steamed potatoes from the steamer basket, carefully wipe the peelings away with a paper towel and transfer to a large mixing bowl. Add the butter to the potatoes using a potato masher until the potatoes are well mashed. Slowly incorporate the half and half, mashing and stirring until just enough of the half and half has been incorporated and the potatoes are the consistency you prefer. Stir in the salt and pepper and serve.
