## Instructions
1. Preheat your oven to 375°F (190°C) and line baking sheets with parchment paper.
2. In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
3. Beat in the eggs one at a time, then stir in the vanilla extract.
4. In a separate medium bowl, whisk together the flour, baking soda, cinnamon, nutmeg, and salt.
5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
6. Stir in the old-fashioned rolled oats, diced apple, and optional chopped nuts until evenly distributed.
7. Drop rounded tablespoons of dough onto the prepared baking sheets, leaving about 2 inches between cookies.
8. Bake for 10-12 minutes, or until the edges are golden brown and the centers are set.
9. Remove from the oven and let cool on the baking sheets for a few minutes before transferring to a wire rack to cool completely.
**Short Tips**
* For extra apple pie flavor, you can toss the diced apples with a pinch of cinnamon and a teaspoon of sugar before adding them to the dough.
* Don’t overmix the dough once you add the flour, as this can make the cookies tough.
* If your apples are very juicy, pat them dry with a paper towel before adding them to prevent the cookies from becoming too wet.
* These cookies freeze well! Once cooled, store them in an airtight container in the freezer for up to 3 months.
* Enjoy warm with a scoop of vanilla ice cream for an extra indulgent treat!
