The American peanut butter cookie has gotten bigger, richer, and bolder tasting over the years, but usually retains its characteristic crisscrossed top. My decadent, updated family-pleasing version features a butter-and-brown-sugar-dough studded with semisweet chocolate and peanut butter morsels. Both kinds of morsels add bursts of flavor, and the peanut butter chips contribute an appealing creaminess too. For extra peanutiness, you can toss some chopped, salted peanuts into the dough as well.
Tip: Several manufacturers make peanut butter morsels, but I greatly prefer the Reeses brand. Their morsels taste a lot like their traditional peanut butter cup candies and are a great enhancement to these cookies.
