For the coffee soak, in a bowl add in water, coffee liquer and coffee powder. Mix this really well and set it aside.
For the mascarpone filling, in a bowl, add mascarpone cheese,whipped cream, vanilla and icing sugar. Combine everything really well until no lumps remain.
For the assembly- take a lunchbox. Start by soaking store bought lady fingers in coffee soak and place them on the base of the dish in a single layer. Pipe a generous layer of mascarpone filling over these soaked ladyfingers and spread it evenly. Repeat the process one more time.
Dust cocoa powder and cover the top entirely. Refrigerate the tiramisu for 6-8 hrs or overnight and serve!
