Lightly grease a 7-inch round pan and line with parchment paper.
In a large mixing bowl, whisk together the flour, sugar, salt, baking soda and cinnamon.
Stir in the egg, coconut oil and vanilla until mixture forms into batter.
Using a wooden spoon or spatula, gently fold in the oats and raisins until thoroughly combined.
Press the cookie dough into the prepared pan and press it into an even layer.
Add 1 cup of water to the Instant Pot. Cover pan with foil or parchment (to prevent condensation from damaging cookie), place covered cookie pan on trivet and lower trivet into Instant Pot.
Secure and lock the Instant Pot lid and set valve to Sealing. Select Manual/Pressure Cook and set to HIGH pressure for 25 minutes.
Once cooking is complete, allow the pressure to release naturally for 10 minutes before moving the valve to Venting to release remaining pressure. Once float valve drops (after all pressure is released), unlock and remove the lid.
Using pot holders, remove the trivet and cookie pan from the Instant Pot. Allow cookie pan to cool on a wire rack for about 1 hour before cutting.
Before serving, cut into 8 equal wedges (like cutting a pizza). Enjoy plain, or with a scoop of vanilla ice cream or frozen yogurt.
Place any leftovers in an airtight container and store in the refrigerator.
