Instant Pot Carrot Cake with Cream Cheese Frosting

"Yes, you can cook carrot cake in an Instant Pot - it's super easy and the steaming cooking process results in an incredibly moist cake! This is probably one of our all-time favorite cakes. This version of carrot cake uses whole wheat flour, which adds a little extra texture and holds up better to the steam. We also use a pinch of orange zest, which in our opinion elevates the cream cheese frosting from absolutely delicious to spectacular. "
