milk, maple syrup, or freshly whipped cream(optional)
Select simmer/saute on the pressure cooker and add the butter to melt. Add the oats. Toast for about 3 minutes, stirring constantly, until they're fragrant and smell nutty.
Stir in the water, carrots, spices, raisins, pecans, and brown sugar. Lock the lid in place and select high pressure for 10 minutes.
When the cook time ends, turn off the pressure cooker. Quick release the pressure or allow it to release naturally. Stir the oatmeal and either serve or cover again and allow the oatmeal to reach your desired thickness.
Serve topped with milk, maple syrup, or whipped cream.
The actual "pressure cooking" time for this oatmeal is only 10 minutes, However you'll want to allow about 10-15 minutes for the pressure cooker to come to cooking temperature and an additional 5-10 minutes as needed to thicken the oatmeal while resting.
