Preheat your oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan or line it with parchment paper for easy removal.
In a medium bowl, whisk together the all-purpose flour, baking soda, and salt. Set aside.
In a large mixing bowl, use an electric mixer to cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
Add the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract.
Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Be careful not to over-mix.
Fold in the semi-sweet chocolate chips using a rubber spatula until evenly distributed throughout the batter.
Spread the batter evenly into the prepared baking pan.
Bake in the preheated oven for 25-30 minutes, or until the edges are golden and a toothpick inserted into the center comes out clean.
Remove from the oven and allow the cake to cool in the pan for about 10 minutes. Then transfer the cake to a cooling rack to cool completely.
