Chocolate Peanut Butter Shortbread Squares
The milk-chocolate topping of these cookies looks like the result of masterful piping, but it's actually a cinch to make using a mold. Beneath the chocolate hides a layer of peanut butter on top of brown-sugar shortbread, all of them adding up to a treat that's creamy and crumbly and rich throughout.
You will need a basket-weave mat (we used an 8"-by-16" rubber texture mat in basket weave (PA 01-6), $12, from chineseclayart.com) to imprint the chocolate with the woven motif. To make the squares without a mat, spread the melted chocolate atop the peanut butter layer, and refrigerate until firm, about an hour.
