Using a hand or stand mixer, combine the butter, egg, brown sugar, white sugar, vanilla extract, and water.
In a separate bowl combine flour, baking powder, and salt with a fork.
With the mixer on low speed, add the flour mixture 1/2 cup at a time until it is combined.
Beat on medium speed for 1-2 minutes, scraping down the sides of the bowl with a spatula as needed. Mix in the chocolate chips.
Line a cookie sheet with aluminum foil, dull side up.
Use an ice cream scoop or a 1/3 cup measuring cup and scoop out enough dough for 2 cookies.
Roll the dough into 2 balls and place 2 balls on the cookie sheet with plenty of room to spread out.
If the cookie sheet is large enough, use 3 or 4 balls of dough. I don't recommend making more than 4 cookies on one cookie sheet at a time.
Preheat oven to 350°.
Place the cookie sheet with the cookies on it, in the freezer for 15 minutes. Do not skip this step.
Place the ice cold cookie sheet with cookies into the preheated oven and bake for 10 minutes.
Remove the cookies and bang the cookie sheet on the countertop 3-4 times.
Return the cookies to the oven and bake for 3 minutes.
Remove them from the oven and bang them on the countertop 3-4 times, the cookies should start to spread in circular ripples.
Repeat this process 1 more time - bake for 3 minutes and bang. (Because oven temperatures vary, your cookies may be done at this point and may not need the extra 2 minutes.)
Return the cookies to the oven for 2 minutes. Remove the cookies and bang on the countertop 1 more time.
This time let the cookies cool for 10 minutes at room temperature on the cookie sheet.
Transfer them to a wire rack to cool.
