Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar using an electric mixer until light and fluffy, about 3 minutes.
Add in the vanilla extract and eggs, one at a time, mixing until well combined.
In another bowl, whisk together the flour, baking soda, and salt.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Fold in the semi-sweet chocolate chips using a rubber spatula. If desired, add in the white chocolate chips for a festive look.
Use a cookie scoop or tablespoon to drop rounded dough balls onto the prepared baking sheets, spacing them about 2 inches apart.
If using sprinkles, gently press some onto the top of each cookie dough ball before baking.
Bake in the preheated oven for 10 to 12 minutes, or until the edges are golden brown. The centers may look soft but will firm up as they cool.
Remove from the oven and let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.
Store the cookies in an airtight container at room temperature for up to a week.
For an extra festive touch, try dusting the cookies with powdered sugar before serving.
