Pre-heat oven to 250F and line 2 large baking sheets with parchment paper.
Add the apples slices in a large bowl and add in the maple extract, cinnamon, ginger and coconut oil.
Mix the spice mixture on each apple slice and place on baking sheet - be sure that there are no overlapping apple slices.
Bake for 4 hours. Once time is up, turn off oven and let sit for 1 hour or up to overnight.
