Preheat the oven to 350°F (175°C).

Line a baking sheet with parchment paper.

In a mixing bowl, beat together the softened butter, granulated sugar, and brown sugar until light and fluffy.

Mix in the eggs one at a time, followed by the vanilla extract.

In another bowl, whisk together the flour, baking soda, and salt.

Gradually add the dry ingredients to the wet mixture, stirring until just combined.

Gently fold in the chocolate chips or your chosen mix-ins.

Using a cookie scoop, drop rounded tablespoons of dough onto the prepared baking sheet.

Bake for 10-12 minutes or until the edges are lightly browned.
