The source for today’s recipe is Martha Stewart Living magazine. Easy, fast, and tasty. All you peanut butter lovers, YUM! Has that warm peanut butter cookie taste right out of the oven. The first bite took me back to the elementary school lunchroom peanut butter cake dessert. That was my favorite. And, yes, I could not wait for cupcakes to cool for frosting! Just as good without it. Also, saves money and time not to make the frosting. Great lunch box treat! This recipe is a keeper!
