01 - Preheat oven to 350°F. Line two baking sheets with parchment paper and set aside.
02 - In a medium bowl, whisk together the all-purpose flour, baking soda, and salt until evenly distributed. Set aside.
03 - In a large mixing bowl, beat the softened butter, granulated sugar, and packed brown sugar using an electric mixer on medium speed until the mixture is pale, light, and fluffy, approximately 2 to 3 minutes.
04 - Add the eggs one at a time, beating well after each addition. Pour in the vanilla extract and mix until fully incorporated.
05 - Gradually add the dry ingredient mixture to the creamed butter mixture, mixing on low speed just until the flour is fully incorporated. Avoid overmixing.
06 - Using a rubber spatula, gently fold the semi-sweet chocolate chips, chopped maraschino cherries, and nuts (if using) into the dough by hand until evenly distributed.
07 - Drop rounded tablespoons of dough onto the prepared baking sheets, spacing each portion approximately 2 inches apart to allow for spreading.
08 - Bake for 10 to 12 minutes, or until the edges are lightly golden. The centers should still appear soft and slightly underdone. Do not overbake.
09 - Allow the cookies to rest on the baking sheets for 5 minutes, then transfer them to a wire rack to cool completely before serving or storing.
