Remove apple core. Thinly slice the entire apple. Line a cookie sheet with parchment paper and place apple slices on it. Sprinkle with cinnamon. Bake at 275 degrees for two hours. At the end of one hour flip them over so they bake evenly.
Thumbs up! Um, I was going to take a picture of the finished product but they didn't last long enough... I love easy snack recipes like this! The only "con" is how long it takes to make these. But it's worth the wait. And the house smelled incredible! Highly recommend! I will be making these again!
