Prepare a 9 by 13 pan, lining it with a parchment paper sling (check it out here).
In a microwave-safe mixing bowl, melt the butter. Add brown sugar and granulated sugar. Use a fork (or a hand mixer) to mix the sugars and butter together.
Add vanilla and eggs. Mix until the ingredients are fully incorporated.
To the center of the bowl add the salt and baking soda. Mix.
Add the flour and mix until combined.
Mix in the chocolate chips. Spread evenly into the pan.
Bake about 30 minutes until crispy around the edges but still a little gooey in the middle. Let sit for 20 minutes in the pan before lifting out with the parchment paper. Cool before cutting into bars. Enjoy!
