Add butter, salt, brown sugar, cinnamon and water.
Cover the pot and make sure the vent on the top of the cover is set to "Sealing".
Press the "Pressure Cook" or "Manual" button. Set the timer for 4 minutes.
Once the carrots are done cooking, switch the vent to "Venting".
Stir carrots and serve.
Notes
Make Ahead. If you want to make these carrots ahead of time you can, I would suggest only a day ahead. Store them in an air-tight container in the fridge.
Reheat. Place them into a pan with about 2 Tablespoons of butter, and cook until heated through.
Store. Leftovers can be stored in an airtight container in the fridge for 2-3 days. Reheat in the microwave or in a pan on the stove.
Swap the brown sugar. You can use maple syrup or honey with great results.
Mix things up. Add more root vegetables such as parsnips, potatoes, and golden beets all work well!
Add nuts. Sprinkle the carrots with some pecans or walnuts just before serving.
Release the pressure right away. Don't let your pressure cooker release the steam naturally, this will result in overcooked carrots.
