This Oatmeal Chocolate Toffee Skillet Cookie Makes Baking Cookies Even Easier

Sadly, summer has passed, but wonderful memories remain.  What I love about summer is the simplicity: relaxed schedules, easy meals and later bedtimes.  There is no rush and with that, at least in my house, there is no fuss (well, there is less of it…).  This is a simple skillet cookie recipe that I created for my younger son who, like myself, is a cookie lover.  I have added oatmeal and toffee to make a bit more interesting, and according to my son and husband, delicious.skillet cookie

This easy recipe is baked in a cast iron skillet and makes me think of campfires and glorious lazy days.  Cookies are a fairly easy thing to make already, but placing the entire batter into a cast iron pan makes them even easier, including for all my non-baker friends.
