Preheat your oven to 350°F (175°C).

In a stand mixer or a large mixing bowl, add the softened unsalted butter and granulated sugar. Beat together at medium speed for about 2-3 minutes until light and fluffy.

Add the vanilla extract and mix until fully combined.

Gradually add in the all-purpose flour and salt, mixing on low speed until the dough starts to form a crumbly texture.

Fold in the mini chocolate chips using a spatula or wooden spoon.

Lightly grease or line a 9x9 inch baking pan with parchment paper. Transfer the cookie dough into the pan and press down evenly.

Bake for 15-17 minutes until the edges turn golden brown and the center remains slightly soft.

Allow cookies to cool slightly in the pan, then cool completely on a wire rack before cutting into bars or triangles.
