A chocolate cookie for those who like to sneak some nutrition in when the kids (or husbands!) aren't looking. Brownie-like taste and texture. My grandsons originally called these mud pies ; the nuts and chips were the pebbles , and the name evolved from there. This is a tweaked version of an old family recipe. We like it without fruit, but my neighbor swears it's much better with a handful of dried cherries added; she also likes to use part whole wheat flour.
