Chocolate Chip Cookies Challenge

Chocolate chip cookies is one of the favorites for many.  My friends seem to know how to bake them, but not I.  Over the years, I only had one 'gwey' chocolate chip cookies that turned out with a wow.  But, I forgot to write down the ingredient measurements, and how.  So after twenty some years, it's start all over for the search for the best gwey chocolate chip cookies.  As a start, this year, I tried this recipe that was printed in the back of 25 lb All Purpose flour I bought.  The ingredients seems to be a bit different than the ones in the back of the chocolate chip package, so I decided to give it a try.
Well, the result of the taste is - very good.  Texture:  I would like to improve on it.
My friends tell me not to beat the eggs and butter like I do with my cakes with the mixer.  So, I basically beat and mixed everything manually with whisk and spatula.  Then, scooped the cookie dough with the 1 Tbsp cookie scoop.   Placed each one on top of the Silpat over the cookie sheet and baked at 350'F as recommended.  I also made sure to chill the dough before each handling because it is quite warm in my kitchen during the summer - 80 - 84'F.  I was also short in time, so I put the dough in the freezer for 2 min before each use.
My friends bake for 8 min.  I followed my recipe and baked for 12 min.  But they did not brown as theirs do.  They said to bake at 375'F the next time.   If you have a chocolate chip cookies recipe that is gwey or chewy, do please share with me.
I took my batch to the office and my friend brought her batch.  Well, it's like night and day difference.  Her's look nice and brown and soft.  Mine is pale and soft after 12 min.  or Brown and dry - after 17 min of baking to get them browned.  But taste wise, we like both.    Texture wise, my friends chocolate chip cookies win.
