Preheat the oven to 350 degrees.
Line a 9×13 baking pan or casserole dish with parchment paper and then spray lightly with oil or cooking spray. Be sure to leave a little hanging over to make removal easy.
Combine butter, granulated sugar, and brown sugar in a large mixing bowl and beat together until fluffy.
Add the eggs and vanilla and then beat until just combined.
Slowly stir in the flour, baking soda and salt, mixing until just combined.
Fold in the chocolate chips, reserving a small portion to add to the top.
Spread the dough into the prepared pan. It’s pretty sticky, so I like to lightly wet my hands with water and press the dough into an even layer.
Top with reserved chocolate chips and then bake for 35-40 minutes, or until golden brown.
Allow to cool to room temperature before removing from the pan and cutting.
