Spoon the mango puree on to the bottom of your glass.
To make the milk layer pour in your milk, half maple syrup and 2 cubes of ice in the cocktail shaker. Shake for a few seconds until it's all chilled and combined. Taste if it is sweet enough for you and add more sweetener and shake again. Pour over the mango layer slowly making sure you have at least 1 inch gap. Add ice making sure there is still a gap for the pandan.
Next make the pandan layer. Wash out your cocktail shaker and add in the pandan powder, the rest of the maple syrup and 2 cubes of ice. Shake until well blended and pour over the milk layer.
Drink right away.
Notes
So this does not have any coffee in it, but you can add a shot of expresso along with the milk when you are making that layer.
