In a medium bowl, combine all cookie dough ingredients. Microwave for 30 seconds at 600W to soften the butter and cream cheese.
Mix well and knead by hand until you have a smooth dough.
Once slightly cooled (you may refrigerate for 10 minutes), shape the dough into a ball.
Take small portions and roll them into balls with your hands. Place them on a baking tray lined with parchment paper. Flatten each ball gently into a round cookie shape. Do not worry if they are not identical.
Preheat the oven to 180°C (350°F). Bake for 10 minutes on one side, then flip and bake for 5 more minutes.
Remove from the oven and let the cookies cool on a wire rack.
For the decoration, melt the chocolate with the milk and butter in a bowl (20–30 seconds in the microwave at 600W). Stir until smooth.
Dip or drizzle the cooled cookies with the chocolate mixture. Sprinkle with shredded coconut if desired.
