Make sure not to overcook the cookies. They are meant to be moist in the middle so, if unsure about cooking times, less is the better option.
I'm a tough bloke who likes beer and lifting heavy things. I had some PB and some condensed milk and thought: Hey, there's got to be a recipe incorporating both these ingredients. A quick Google search later and i found this recipe. Well as a tough bloke let me tell you- They were absolutely darling!! Really simple and super delicious and scrumptious. Next time I'm going to incorporate mini m&m's. Make sure u take them out SOFT at 8 minutes, they continue to get harder. - 19 Jun 2015
