Start by preheating the oven to 350ºF. Prepare a baking sheet with parchment paper.
First, peel the apples and dice them into small pieces. Spread the diced apple on the parchment paper. Bake for 25 minutes and cool. This step can be done the day before.
Next, cream together your sugars and softened butter. Then, add egg and vanilla extract.
Then, combine the sifted flour, salt, baking soda, rolled oats, and spices with the wet ingredients. Now, fold the baked apples into the mixture. Cover the cookie batter and place it in the refrigerator.
Preheat the oven to 350ºF. Allow the cookie batter to chill while the oven preheats. Prepare a baking sheet with parchment paper.
Once the oven preheats, use a cookie scoop to measure out the apple cookies on the prepared pan.
Now, bake for 15-20 minutes or until the apple oatmeal cookies are golden brown. Oven times may vary. Best enjoyed warm.
