Ingredients

Cookies

  • ½ cup (1 stick / 113 g) unsalted butter, room temperature
  • 1 ⅓ cups (267 g) granulated sugar
  • 1 large egg, room temperature
  • 2 tablespoons milk
  • 2 teaspoons vanilla
  • ⅓ cup (39 g) unsweetened cocoa powder
  • 1 ½ cups (187.5 g) all-purpose flour
  • ½ teaspoon baking soda
  • 1 pinch kosher salt
  • ½ cup (100 g) granulated sugar, for rolling

Filling

  • 3 tablespoons unsalted butter, softened
  • 3 tablespoons unsweetened cocoa powder
  • 1 tablespoon honey
  • 1 teaspoon vanilla extract
  • 1 cup (125 g) confectioners' sugar
  • 3 tablespoons whole milk, or heavy cream

Instructions

Cookies

  • To a stand mixer with the paddle attachment, add butter and sugar. Mix on medium speed for about 2 minutes.
  • Reduce the mixer speed to low and add in egg, milk, and vanilla. Mix for about 30 seconds to incorporate. Then, turn the mixer to medium-high and blend until light and fluffy.
  • In a separate bowl, sift cocoa, flour, baking soda, and salt. With the mixer on low, add the flour mixture to the sugar mixture and beat until just combined.
  • Remove the mixer bowl from the stand. Cover and refrigerate the dough for about an hour.
  • When ready, preheat the oven to 375°F and line 2 large baking sheets with parchment paper. Set aside.
  • Using a 2-tablespoon scoop, place dough on the lined baking sheet. Roll each scoop of dough into about a 1-inch ball.
  • Pour remaining sugar onto small plate or bowl.
  • Roll each dough ball in the sugar and place it on the lined baking sheets about 2 inches apart.
  • Bake for 10 minutes, or until set.
  • Remove the cookies from the oven and let them cool for about 10 minutes before adding the filling. While the cookies are cooling, make the filling.

Filling

  • In the bowl of a stand mixer with the whisk attachment (or a large bowl using a hand mixer), add the butter, cocoa, honey, vanilla, and confectioners' sugar.
  • With the mixer on low, combine the ingredients for about 30 seconds.
  • Slowly add milk, one tablespoon at a time, until you reach your desired consistency. You may not need all 3 tablespoons. On the other hand, you may need 1 more tablespoon; it can vary from season to season and kitchen to kitchen.
  • Spread filling on the bottoms of half the cookies and top with the remaining cookies.
