If you are using small glasses like those shown in the photos, you will need approx. 3 ladyfinger biscuits per glass. This will vary depending on the size of your glass and the size of the ladyfinger biscuits.
I prefer to make one glass of tiramisu at a time.
Break each ladyfinger biscuit into 3 pieces.
Dip the edges of each biscuit into the coffee. You want just enough coffee to dampen the edges of the biscuit, but not soak the biscuit all the way through.
Arrange 3 pieces of soaked biscuits on the bottom of the glass.
Dollop a tablespoon of the cream filling on top of the soaked biscuits. You can simply use a spoon for this task, or a piping bag for cleaner edges.
Repeat the above steps until you have 3 layers of biscuits and 3 layers of cream filling.
Repeat for the remaining 5 glasses.
Refrigerate the tiramisu for at least 1 hour.
Sprinkle with cocoa powder just before serving.
