Let’s get into the fun part—baking! Here’s how you can whip up a batch of these delightful cookies:

1. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy, about 3-4 minutes.
3. Add the eggs, one at a time, beating well after each addition. Stir in the vanilla extract.
4. In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon if using.
5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
6. Fold in the chopped pecans until evenly distributed throughout the dough.
7. Drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart.
8. Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden. Remember, the cookies will continue to cook on the baking sheet after you take them out of the oven.
9. Allow the cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
