Mix milk and coffee in a small bowl.
Start by setting up your station: Biscuits, Mascarpone mixture, Milk/coffee mixture, lotus spread.
Start by dipping the biscuits one at a time into the milk/coffee and laying them in the bottom of the square dish, to line the whole bottom (total 16 biscuits).
Then put about 1/3 of the cheesecake mixture on top of the biscuit layer and smooth it out with an inverted spatuala (or regular spatula).
Repeat this with the rest of the ingredients.
Melt about half of a jar of lotus spread in the microwave for 30 seconds, you can do this directly in the lotus jar if you are careful to remove all of the foil top (or you can put the spread in a microwave safe bowl).
Pour melted lotus on top of the last cheesecake layer. Cover with saran wrap and refrigerate until set, about 5 hours or overnight.
