Preheat the oven to 350℉. Prep the baking trays by lining them with parchment paper and set aside. Melt the butter in the microwave or using a double boiler method and set aside to cool for at least 10 minutes while you prep the rest of your ingredients.
Into a large bowl, whisk the brown sugar, white sugar, and melted butter.
1/2 cup butter, 1/3 cup dark brown sugar, 1/3 cup white sugar
Add in egg and vanilla and continue whisking.
1 egg, 1 tsp vanilla
Add in flour, baking soda, and salt. Fold until a soft dough forms.
3/4 tsp baking soda, 1 1/2 cups all-purpose flour, 1/4 tsp salt
Mix in chocolate chips.
1/2 cup semi-sweet chocolate chips
Scoop 6 cookie dough balls and place on the prepared cookie sheet.
Bake for 12-15 minutes. Mine took 14 minutes. The cookies will be ready when the edges are a light brown, but the inside will look very soft. Remember not to over-bake! They continue to bake as they cool on the hot tray. Remove from oven and add a few more chocolate on top if desired. Sprinkle flakey sea salt (optional but recommended).
Let the cookies cool on the hot pan for a few minutes before serving warm or cool completely and enjoy!
