I often read other facebook friends' blogs to get new recipe ideas, and sometimes it can lead to great/awful things. In this case, it lead to both because this recipe was so good that I couldn't stop eating the result!
So here's the recipe. I altered it a bit by using Hershey's milk chocolate chip/peanut butter chip mix, and omitted the sugar on top. I also didn't have light brown sugar, but regular brown sugar worked just as well.
Tip: I keep cookies moist by putting a piece of white bread in the cookie jar/bag. The starch keeps them soft. It also works well with brownies.
