I absolutely love a good Oatmeal Cookie. I have tried all kinds of recipes. Most of them call for raisins and walnuts. I thought I would give the underdog of dried fruits a go at this. The prune is highly under rated for its flavor and usefulness. I have always liked them myself...I mean, it's just a dried plum, for Pete's Sake....and I think most people like plums. The prune would pair well with walnuts, but you can't deny the beauty of a good buttery pecan flavor. Pecans are the subtler nut. I hope you try this recipe as I have published it. You could substitute raisins and Walnuts.
