In a pot, heat butter and start cooking it until brown. Crush the chocolates into bits. Once the butter browns, pour it into the mixing bowl, and add coffee. Keep mixing for about 2 minutes to infuse the coffee flavour well.

Now add both the sugars and beat well so no crystals remain.Then add the eggs and mix well so the mixture comes together. After, add the dry ingredients in 3 stages.

Now add the chocolate and give it a final mix for the dough to bind well. Scoop out dough balls, weigh it to be 57 gm/ 2 oz each. Shape into balls and freeze for a minimum of 36 hours. Maximum could be 3 to 4 days. Bake at 180 degrees for 15 to 18 minutes until the edges are golden and the center is soft yet dry from the top. Cool the cookies for 5 to 10 minutes and enjoy with glass of milk or coffee as you prefer.
