How to space out your cookies
While it might be tempting to put all of your cookies on one tray - its not normally a good idea! Cookies need plenty of space between them as that little ball of dough will turn in to a cookie almost twice as big!
Try to leave at least 4cm (1.5 inches) between your cookies when laying them out as this gives them plenty of room to do their thing without sticking together.
Another good reason to space them out is that it allows the heat from your oven to circulate around each cookie and this will help them to have an even bake - resulting in a perfect cookie for you to enjoy!
