Ingredients
  

For the cookies:

  • ½ cup butter softened
  • 1 cup granulated sugar
  • 1 egg
  • ¾ cup buttermilk or substitute 1 tablespoon of white vinegar + almost ¾ cup regular milk
  • 1 teaspoon vanilla
  • ½ cup cocoa
  • cup flour
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup chopped pecans

For the frosting:

  • 3 oz unsweetened chocolate
  • cup 5⅓ tablespoons butter, softened
  • 3 cups powdered sugar
  • 1 teaspoon vanilla
  • 2–3 tablespoons milk

Instructions
 

For the cookies:

  • Place the butter and sugar in the bowl of a stand mixer. Beat on medium speed until fluffy, about 3–4 minutes.
  • Turn off the mixer and add the egg. Beat until combined.
  • In a medium bowl, combine the cocoa, flour, baking soda, and salt. Whisk to combine.
  • With the mixer on low, add half of the buttermilk. Once it is incorporated, add half of the flour mixture. Repeat with the remaining buttermilk and flour mixture.
  • Add the chopped pecans and mix until just combined. Refrigerate the dough for at least 2 hours, or up to 48 hours.
  • Preheat the oven to 375°. Use a spoon to scoop out one tablespoon of dough and place on a cookie sheet lined with parchment paper or a silicone mat. Repeat with the remaining dough, leaving 3 inches of space between each tablespoon of dough (the cookies will spread).
  • Bake for 8–10 minutes, until the cookies no longer look wet on top. Let sit for 5 minutes on the cookie sheet. Remove the cookies and place on a cooling rack.

For the frosting:

  • Place the unsweetened chocolate in a microwave-safe bowl. Microwave in 20 second increments until melted.
  • Place the softened butter, melted chocolate, powdered sugar, vanilla, and 2 tablespoons milk in a large bowl. Use a handheld mixer to mix until it reaches frosting-like consistency and the powdered sugar is incorporated. Add an additional tablespoon of milk if the mixture looks too stiff.

Frosting the cookies:

  • Use an offset spatula to spread approximately 2 tablespoons of frosting on each cookie. Serve with a tall glass of milk!
