This is a recipe for chocolate chip cookies that took a lot of experimentation to perfect, much to the joy of my house mates. Now I have the perfect recipe for gooey, crackling, delicious cookies!
I use self-raising partly because I always have a stock of self-raising flour in my cupboard and never bother buying plain. However, with this recipe, it actually seems to help make the cookies go really gooey and delicious, by raising them up before they collapse and crack as you take them out the oven.
Also try to make sure they are the same size. I do this by making “quenelles” using two spoons, then squashing the mixture onto the tray. An ice cream scoop would also be a good solution.
