Core 2 pounds granny smith apples and 2 pounds honeycrisp apples and peel if desired. Cut into small chunks and place in Instant Pot.
Add ¾ cup water, 2 cinnamon sticks and 2 Tablespoons granulated sugar. Place the lid on the Instant Pot and make sure the vent is closed.
Cook on high pressure for 8 minutes. Quick release the pressure.
Remove the cinnamon sticks. Use a potato masher for chunky applesauce, or an immersion blender for smooth applesauce.
Enjoy warm or cold.
Store in an airtight container in the refrigerator for up to a week, or freeze for up to 6 months.
Notes
If you want, you can omit the sugar when cooking. Taste the applesauce when done and sweeten to taste. You can use regular sugar, honey, maple syrup, or your sweetener of choice.
