My Instant Pot (both of them) have been life-changing when it comes to getting dinner on the table on time. I started seeing Instant Pot cheesecakes on social media but didn’t see one with a thick peanut butter layer and swirled on top so I developed one! The Instant Pot’s steamy environment is perfect to make a cheesecake and without heating the oven (and your kitchen) for over an hour. This recipe uses the 6 quart duo Instant Pot with the “pot in pot” method.
