What better time to try a new cookie than at a solstice party (even if it was the zillionth rainy day in a row)? (Ok, I realize that this is yet again just a ridiculous justification for cookie baking.) We were going to Marcus and Lisa‘s for a solstice party, and I’d promised to bring cookies, so we whipped up a batch of peanut butter whoopie pies, which were a lot easier than I thought they were going to be. I was surprised that they actually puffed up into the proper little cakey cookies, and I was sure everything was going to fall to pieces when I spread on the peanut butter filling, but all held just fine. I got the recipe from a Martha Stewart Cookie magazine that came out a few Decembers ago; you can see the recipe here. Yum! Enjoy! Definitely more festive than regular old chocolate chip cookies (which had been my original plan).
