Preheat the oven to 350°F (175°C).

Line the baking sheet with parchment paper.

In a mixing bowl, beat the softened butter with both sugars until light and fluffy.

Mix in the eggs and vanilla extract until combined.

In another bowl, whisk together the flour and salt.

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

Fold in the chocolate chips or your chosen mix-ins.

Scoop the dough onto the prepared baking sheet, spacing them about 2 inches apart.

Bake for 10-12 minutes, or until the edges are golden.

Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack.
