Place the sponge fingers in a shallow bowl and pour the ¼ cup of the coffee evenly over the top, ensuring they are well coated. Set aside.
In a separate bowl, place the cream and 1 cup of the custard. Stir through to combine.
In another bowl, place the mascarpone and remaining custard and coffee, combine well.
Scatter 1 teaspoon of cocoa powder into the base of each cup.
Add 1 teaspoonful of the cream mixture and 1 teaspoon of the mascarpone mixture. Then crumble 1 sponge finger among the 6 molds.
Scatter another half a teaspoon of cocoa powder over each layer and continue layering as the first layer until all the cream and mascarpone are complete.
Ensure all are even and finish by scattering the top with more cocoa powder.
Cut aluminum foil into a square the size of the cups and slice a slit into the center of each, wider then the popsicle stick.
Fold and place as flatly as possible on top of each tiramisu and slowly place the popsicle stick through the slit right to the base of each tiramisu.
Set in the freezer for a minimum of 5 hours.
When ready to serve, allow to sit in room temperature for approximately 10 minutes or until it slides out easily.
Enjoy.
