These cookies are based on a recipe that originally appeared in Bon Appetit, for hazelnut shortbread. The first time I made them, I used hazelnuts in the cookie dough but coated them in pistachios because the green color looked nice against the dark chocolate. When I made them again, I used coarsely-chopped pistachios in the dough as well, and I just loved the outcome. either way, I prefer bittersweet chocolate to the milk chocolate called for in the original recipe. —Rivka
Position a rack in center of the oven and preheat to 325°F. Line a large baking sheet with parchment paper.
Whisk flour, baking powder, and salt in medium bowl and set aside. In a large bowl using an hand mixer or in a stand mixer fitted with the paddle attachment, beat butter and sugar until smooth. Add 1/2 cup pistachios and vanilla. Beat in flour mixture until just combined.
Shape tablespoonfuls of dough into logs about 3 inches long. Place on baking sheet, leaving about 1 inch of room between each cookie. Bake until golden brown around edges, 18-20 minutes. Cool completely.
Put chopped chocolate in a double boiler set over barely-simmering water. Stir chocolate until melted and smooth, about 5 minutes. Remove from heat. Place remaining 1/3 cup pistachios in a small shallow bowl. Dip one end of each cookie in the melted chocolate about 1-1 1/2 inches deep. Let excess chocolate drip back into bowl, then roll chocolate-coated end in chopped pistachios. Repeat with the rest of the cookies. Let stand until chocolate has hardened, at least one hour. Cookies will keep in airtight container up to 1 week.
I'm a healthcare consultant by day, food blogger by night, and I make a mean veggie chili. I'm eat a mostly-vegetarian diet, but have a soft spot for meat, especially braised short ribs. And this profile wouldn't be complete without an admission that I absolutely am addicted to cookies and chocolate. Finally, I love the idea of food52 and can't wait to share and read my and others' favorite recipes!
