First, Preheat the oven to 350 degrees F (180 C), and line a baking tray with parchment paper.
In a mixing bowl, add the flour, baking soda, baking powder, salt and whisk to combine.
In a larger bowl, add the cooled melted butter, brown sugar, and granulated sugar. Whisk the ingredients until you achieve a creamy consistency.
Then, add the egg and vanilla extract and whisk to combine.
Next, add the reserved flour mixture into the bowl and gently combine with the help of a spatula.
Then, add the chocolate chips and gently fold until combined with the cookie dough.
Use a large cookie scoop to scoop the cookie dough into balls, placing them a few inches apart. Bake for 11-12 minutes for a softer cookie center or 15 minutes for a crispier cookie. The cookies are ready when the edges are slightly golden, and the center is still puffed. They will look un-done but don't worry, they will continue to bake outside the oven and settle as they cool down. You can add more chocolate chips on top right after you remove them from the oven. Please wait at least 20 minutes before eating until they are cold down and finish baking out of the oven.
