Cut the loaf into bite-size pieces and let it dry overnight on a cookie sheet or pan.
Spray the bottom and sides of your dish with nonstick baking spray.
Whisk the eggs and then add the milk, vanilla, sugar, brown sugar and cinnamon.
Add the dried bread pieces. Let them soak for about 10 minutes. Stirring occasionally to make sure every piece of bread gets into the milk mixture.
Dump the mixture into your prepared dish. Cover the dish really well with foil.
Place your trivet that came with the Instant Pot in the bottom of the pot and pour 1 cup of water into the pot. Place your baking dish on top of the trivet. Place the lid on the instant pot and make sure the vent is turned to “seal”.
Set manual and pressure to high for 40 minutes.
When the timer goes off cover the vent with a towel and quick release the steam.
Remove the dish carefully as it will be hot and remove the foil from the dish draining.
