Break up the biscuits into a bowl. Heat the milk slightly, then stir in the coffee until it dissolves. Sweeten the mixture to your liking with maple syrup or an alternative sweetener.
Pour this over the crumbled biscuits and combine thoroughly. Move the mixture into a small container with a lid, smoothing it flat with a spoon to create the base layer.
Combine the low fat greek yogurt with a generous teaspoon of cream cheese. Layer this mixture over the biscuit base.
Seal the container with the lid and place in the refrigerator to set for at least 30 minutes, or leave it overnight for best results.
Before serving, sprinkle a thin layer of cocoa powder on top for the final touch.
