Chocolate chip Cookies

I have followed many chocolate chip cookie recipes but everytime i make them it turns into one big flat disc , no matter how many times I  have tried the result is the same and I think most of other cookie makers must have experienced this phenomenon.I guess it might be because I stay in a very humid country or maybe the ingredients I use are different but every chocolate cookie recipe I have tried turns out the same and it is actually quite a feat that I have manged to come up with one huge flat disc everytime, so this recipe is for all those cookie makers like myself , so please try this recipe and let me know how this one turns out . So here goes .....
