Preheat oven to 225 degrees. Line a cookie sheet with parchment paper.
Slice the apples very thin using a very sharp knife or a mandolin. The thinner they are the crisper they will be! I sliced them so that the seeds would make a star shape in the middle of each chip. Once you get to where the seeds are, just pop them out with the tip of a knife.
Lay the apple slices on the prepared cookie sheet.
Sprinkle the coconut sugar and cinnamon over the apple chips.
Bake at 225 degrees F for about 1.5 - 2.5 hours. Oven temperatures vary, so after about an hour, you make want to check on the apples periodically.
Once the edges are curled up and the apples are dried and crisp, remove the cookie sheet from the oven. Let the chips cool. then eat! Or store in an airtight container.
Notes
Store leftover chips in an airtight container. They should stay fresh for about 4-5 days.
