Core and cut apples using the apple cutter, or a knife.
Add apples, water, lemon juice, cinnamon and vanilla to Instant Pot.
Using Manual, set Instant Pot to 10 minutes on high pressure. Allow natural release.
Once pressure is released, use an immersion blender or other blender until reaches desired consistency. Use caution and blend in small batches if using a blender when the apples are hot.
