To make the dough: In a large bowl, whisk together the flour, cocoa, malted milk powder, sugar, salt, and baking powder. Work in the butter until the mixture is unevenly crumbly; some larger bits of butter will remain. Stir in the chocolate chunks (or chips).
-
In a separate bowl or large measuring cup, whisk together the egg, vanilla, and milk. Add to the dry ingredients and stir until the dough is evenly moistened and holds together.
-
Line a baking sheet with parchment, and flour the parchment. Scrape the dough onto the parchment and divide it in half. Shape each half into a 6” disk about 3/4” thick, leaving a couple of inches between the two disks.
-
Use a wet bench knife to divide each circle into six wedges. Pull every other wedge away from the circle, to ensure all the scones bake evenly.
-
Loosely cover the unbaked scone dough with plastic wrap and place in the refrigerator for at least 1 hour to chill.
-
When you're ready to bake, preheat the oven to 375°F. When the oven is up to temperature, bake the scones for 16 to 18 minutes, until the edges looked fully baked.
-
Remove the scones from the oven and cool on the pan for 5 minutes before transferring to a rack to finish cooling.
-
To make the glaze: Sift the confectioners’ sugar and malted milk powder through a strainer into a small bowl. Add the milk gradually, stirring as you go; add just enough milk to make a drizzle-able glaze. Drizzle over the cooled scones.
