Preheat oven to 180ºC (356ºF) fan-forced. Line a baking tray with parchment paper and set aside.

In a large mixing bowl, add flour.

Add cold cubed butter and using your hands, rub the butter into the flour until it reaches the consistency of coarse crumbs, this takes about 2 minutes.

Add brown sugar and cocoa powder, mix until well combined.

Make a well in the middle and add beaten and milk. Mix until a cookie dough forms, using your hands for this step makes it easier.

Scoop up 1 tablespoon worth of dough and roll into a smooth ball. Flatten ball in the palm of your hand to form a round disc, place cookie disc onto lined sheet. Alternatively, place ball on lined tray and press down with the palm of your hand to flatten out into a round disc.

Repeat with remaining dough, leaving about 5cm space between each cookie.

Bake for 12-15 minutes and until cookies come away easily from the parchment paper.

Remove and cool on sheet for 2 minutes.

Transfer to a wire rack to cool completely.

Drizzle each cookie with the melted dark chocolate. Set aside and allow them to set.

Serve and enjoy!
