Whisk together the flour, cocoa powder, baking soda, and salt. Set aside.
Using an electric mixer on medium speed, beat the butter and brown sugar until light and fluffy. Add the honey, and mix well.
Reduce mixer speed to low. Gradually add the flour mixture, mixing just until combined. Mix in the chocolate.
Refrigerate the dough for 30 minutes.
Preheat oven to 325°F (160°C). Line baking sheets with silicone liners or parchment paper.
Using about a teaspoonful of dough at a time, roll the dough into balls. Roll each ball in sugar to coat.
Place the dough balls about 1 inch apart on the prepared pans. Bake (one pan at a time) 10 minutes, or until the tops of the cookies crack and the cookies are set.
Cool the cookies on the pans on wire racks for 5 minutes. Then transfer the cookies from the pan to a wire rack to cool completely.
