Ingredients

Cookies

  • 1 cup (170 g) semisweet chocolate chips
  • 1 cup (227 g) unsalted butter softened
  • 3/4 cup (150 g) granulated sugar
  • 1/4 cup (55 g) light brown sugar packed
  • 1 large egg
  • 1 egg yolk
  • 1 1/2 tsp (7 ml) vanilla extract
  • 1 1/4 cups (157 g) all-purpose flour
  • 1/4 cup (24 g) unsweetened cocoa powder natural, not Dutch-process
  • 1/2 tsp (2 g) baking powder
  • 1/4 tsp (1.5 g) baking soda
  • 1/2 tsp (3 g) kosher salt

Chocolate Glaze

  • 1/2 cup (113 g) unsalted butter
  • 1/4 cup (24 g) unsweetened cocoa powder natural, not Dutch-process
  • 3 tbsp (45 ml) buttermilk
  • 2 cups (240 g) powdered sugar sifted if lumpy
  • 1 tsp (5 ml) vanilla extract
  • chopped pecans (optional) for glaze, stir in as desired

Equipment

  • Mixing bowls
  • Electric mixer
  • Baking sheet
  • Parchment paper
  • Wire rack
  • Small Saucepan

Instructions
 

  1. Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
  2. In a microwave-safe bowl, melt the semisweet chocolate chips in 30-second bursts, stirring between rounds, until smooth and glossy. Let cool slightly.
  3. In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
  4. In a large mixing bowl, using an electric mixer, cream the softened butter, granulated sugar, and brown sugar until fluffy and pale, about 2–3 minutes.
  5. Add the egg, egg yolk, and vanilla extract. Beat on low speed to combine. Mix in the cooled melted chocolate until incorporated.
  6. With a spatula, fold in the flour mixture just until the dough comes together. If the dough is very soft or sticky, refrigerate for 30–60 minutes.
  7. Scoop tablespoon-sized dough balls onto the prepared baking sheet, spacing them apart. Bake for 8–10 minutes, until edges are set but centers still look soft.
  8. Let the cookies cool on the pan for 5 minutes, then transfer to a wire rack to cool completely before frosting.
  9. For the chocolate glaze: In a small saucepan over medium heat, melt the butter. Whisk in the cocoa powder and buttermilk until combined and smooth. Bring just to a bubble, then remove from heat.
  10. Immediately whisk in the powdered sugar and vanilla until no lumps remain and the glaze is glossy. (Stir in chopped pecans now, if using.)
  11. Spoon the warm glaze over each cookie, spreading gently to the edges. Let stand 10–15 minutes for the glaze to set before serving.

Notes

Storage: Store in an airtight container at room temperature for 3–4 days, layered with parchment to prevent sticking. To freeze, place cookies on a tray to freeze solid, then transfer to a freezer-safe container for up to 2 months.
Variations: Use milk or dark chocolate chips, add a teaspoon of espresso powder to the dough, or stir pecans into the glaze. No buttermilk? Substitute 3 tbsp milk plus 1 tsp lemon juice or vinegar, and let stand 5 minutes.
