Preheat the oven to 180° C (350°F) for 10 minutes. Line baking tray with parchment paper.
In a bowl add in the chopped chocolate and butter. Melt them together using double boiler method. You can microwave them in a microwave safe bowl for few seconds stirring well in between until the chocolate is completely smooth and melted. Do not overheat the chocolate as this can burn it.
Add in brown sugar, cocoa powder to the melted chocolate mixture and combine them.
Add in vanilla essence, milk, coffee powder, oil and mix well until combined.
Sieve in the flour, baking powder and salt. Mix until combined. The dough will be soft.
Cling wrap the bowl and refrigerate it for 10-15 minutes.
Scoop a tablespoon of the dough and gently press down the scooped dough. You need to press only slightly and not completely flatten the dough.
I have top some of the cookies with chocolate chips.
Use a standard size cookie scoop to scoop out the cookies onto the prepared baking tray. I used 1 tablespoon measuring spoon to scoop the dough.
Keep some distance in between the cookies as the cookies will expand as it bakes.
Bake the cookies at a preheated oven @180° C for 12 minutes or until the cookies have crackled and are set on the edges, but still gooey in the middle.
Remove from the oven and allow to stand for 5-10 minutes, then transfer them onto a cooling rack.
Enjoy once the cookies has cooled down completely.
