Preheat the oven to 350 degrees.
Line baking sheets with parchment paper or silicone baking mats.
Add the flour and baking soda to a medium bowl and mix together with a fork or whisk.
Cut the butter into pieces roughly tablespoon sized pieces.
Place the butter into a microwave proof container and microwave it until melted, about 30-40 seconds. I didn't melt it 100% because I was impatient, but it should be almost entirely melted.
Add the butter to the bowl of a stand mixer. (You can do this entirely with a spoon if you don't have a mixer.)
Add the brown sugar and the granulated sugar and beat until smooth. I beat it on low speed for about two minutes.
Add the two eggs, one at a time, beating until combined between each one.
Add the vanilla and mix.
Add the dry ingredients. Mix until combined, but don't overdo it.
Make sure to scrape up from the bottom of the bowl and down from the sides so that everything is combined.
Add the chocolate chips to the cookie dough, mixing by hand.
Using a cookie scoop or a tablespoon, drop large scoops of dough onto the prepared cookie sheets. You have to leave a pretty decent amount of space between the scoops as they will spread as they bake.
Bake on the middle racks for about 15 minutes, until golden. If you bake two sheets at the same time, make sure you rotate the trays about halfway through.
Let the cookies cool for two or three minutes, then transfer them to a wire rack. When completely cool, store the cookies in an airtight container. I used a large Ziploc and the cookies stayed chewy for as long as we had them - which wasn't long.
