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 light brown sugar using an electric mixer on medium speed until pale, light, and fluffy, approximately 2 to 3 minutes.
04 - Add 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 wet ingredients, mixing on low speed just until the flour is incorporated and no dry streaks remain. Do not overmix.
06 - Using a rubber spatula, gently fold in the semi-sweet chocolate chips, chopped maraschino cherries, and nuts if using. Distribute evenly throughout the dough without overworking.
07 - Drop rounded tablespoons of dough onto the prepared baking sheets, spacing each portion about 2 inches apart to allow for spreading.
08 - Bake for 10 to 12 minutes, rotating pans halfway through, until edges are lightly golden. The centers should still appear slightly soft and underbaked.
09 - Allow cookies to rest on the baking sheets for 5 minutes to set, then transfer to a wire rack to cool completely.
