Preheat your oven to 375°F (190°C). Line your baking sheets with parchment paper or silicone baking mats.
In a medium bowl, whisk together the all-purpose flour, baking soda, and salt. Set aside.
In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar with an electric mixer until light and fluffy, about 2 to 3 minutes.
Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
Gradually add the flour mixture to the wet ingredients, mixing on low speed just until combined. Avoid overmixing.
Fold in the chocolate chips, optional chopped nuts, and colorful sprinkles.
Drop rounded tablespoons of dough onto the prepared baking sheets, spacing about 2 inches apart. Bake for 9 to 11 minutes, until edges are golden but centers remain soft.
Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
