The combination of chocolate and peanut butter is one of my favorite things. These cookies have both chocolate and peanut butter in the dough and then again in the chips, in the form of the tiniest pb cups ever, from King Arthur Flour. Though micro-mini pb cups are hard to find and you might be tempted to use pb chips and chocolate chips instead, I can say from experience that the cookies will not taste the same, nor half as good. These pb cups don't melt into the dough, and they actually taste like peanut butter, which is not always the case. The recipe, also from KAF, can be found here.
