01 - Peel, core, and slice the apples into 1/2-inch wedges using a vegetable peeler and sharp knife.
02 - Place the apple slices into the Instant Pot insert. Sprinkle brown sugar, cinnamon, nutmeg (if using), and salt evenly over the apples.
03 - Drizzle maple syrup or honey over the apples if using, then pour in the water or apple juice.
04 - Distribute the butter pieces evenly across the top of the apple mixture.
05 - Close the Instant Pot lid and ensure the steam release valve is set to sealing. Cook on high pressure for 2 minutes.
06 - Allow the pressure to release naturally for 3 minutes, then carefully quick-release any remaining pressure.
07 - Open the lid and gently stir in the vanilla extract. For a thicker syrup consistency, select Sauté mode and simmer for 2-3 minutes, stirring occasionally.
08 - Serve warm over oatmeal, pancakes, or ice cream. Makes an excellent dessert or breakfast topping.
