For the Raffaello tiramisu, line the loaf pan with baking paper.
Mix the egg yolks with the sugar until foamy, add the mascarpone, add the coconut flakes and chill briefly.
Then mix coconut milk with rum, briefly turn the biscuits in it and put the first layer of biscuits in the form.
Spread a thin layer of the cream on top, then the biscuits again, etc. until all the utensils are used up.
Put the Raffaello tiramisu in the refrigerator for at least 1 hour (ideally 3 hours), then turn out and sprinkle with remaining coconut flakes.
