10/2/16 Updated Note: Originally, this recipe was created using a 9-inch spring form pan, which fits comfortably in the Instant Pot IPDUO 80.
After making the recipe again in a 7 inch pan, I found that you will need to adjust the pressure cooking time for this size, as the thickness of the brownies increases. Total pressure cooking time should be 30 minutes and steam release method should be NPR for 10 minutes.
