My flawless vegan tiramisu with home-made coffee-soaked savoiardi sponge fingers and a smooth mascarpone style cream.
In a wide bowl, whisk together the espresso, rum and caster sugar until no granules of sugar remain.
One by one, dunk each savoiardi sponge finger in the coffee mixture, flip and dip again, before placing in a row on the bottom of a deep 21x15cm dish.
Once you have a row of 5 or 6 sponge fingers (depending on the size of your dish) across the base of the dish, pause the dunking and make the cream layer.
Place all the cream layer ingredients in the cup of a high-speed blender and blend until smooth. If the mixture appears to have split or doesn't quite look smooth, put the lid on the blender cup and sit it in a bowl of just-boiled water for 5-10 minutes before blending again.
Pour half of the cream mixture over the bottom layer of soaked savoiardi sponge fingers. Give the dish a gentle jiggle to even out the cream layer and fill the cracks between the sponge fingers.
Continue dunking and arranging the remaining sponge fingers in a second layer on top of the first then top with the remaining cream mixture. Use a pallet knife or spatula to flatten off the surface then cover with cling film (making sure it's not touching the cream surface) and place in the fridge for at least 4 hours or ideally overnight.
Once ready to serve, dust with the cocoa powder and finely grate with the vegan dark chocolate.
