Preheat oven to 350℉
First, you'll need to make melted butter. I recommend microwaving the stick of butter in a microwave-safe bowl for increments of 10 seconds. Once 90% of the butter is melted, stir around so the last bit of solid melts. Be sure to cover it well so if it does pop, it doesn't make a mess inside the microwave.
In a large mixing bowl, add sugar and salt. Then add the butter and mix until uniform.
Add an egg and vanilla extract and mix again until mixture is once again uniform.
Add the dry ingredients: all-purpose flour, baking soda, and baking powder. Mix until you achieve cookie dough making sure there are no clumps.
Lastly, fold in the chocolate chips.
Portion onto a baking sheet lined with parchment paper. I recommend the purple-colored Vollrath #40 cookie scooper (see links below recipe). Be sure to give each ball of dough enough space to spread.
Bake in the preheated oven at 350℉ for 12-15 minutes until the edges start to brown.
Remove from oven and let cool before enjoying!
