Start by taking the butter out of the fridge and letting it soften at room temperature for about 30 minutes. Once it’s soft, place the butter in a large mixing bowl and beat it together with brown sugar and granulated sugar using an electric mixer on medium speed for 5-7 minutes.

Next, incorporate the eggs into the butter mixture one at a time. Make sure to mix well after each addition to ensure they're fully combined. Then, add the vanilla extract, giving it a good mix until the batter is smooth and creamy.

In a medium bowl, whisk together the all-purpose flour, ground cinnamon, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing gently with a spatula.

Now it’s time to fold in the old-fashioned oats and chopped dried apples, gently incorporating them into the dough until evenly distributed.

Prepare two ungreased baking sheets, spacing them to allow room for spreading. Using a rounded tablespoon, drop heaping spoonfuls of the dough onto the sheets.

Preheat your oven to 350°F and bake the cookies for about 10-12 minutes. Allow the cookies to cool on the baking sheet for a minute before transferring them to wire racks to cool completely.
