I said it was easy and I wasn't lying. Beat the cream cheese and sugar then add the mascarpone cheese until light and creamy. Fold in your whipped cream and that's your base for the dessert! Take each lady finger one at a time and quickly dip it into the lemonade for about 2-3 seconds. The lady finger will absorb the liquid and end up with a texture just like a regular sponge cake! Make sure not to dip it in the lemonade for too long or the lady finger will take on too much liquid and just dissolve on you. Tiramisu cake is always better made the day before you need to serve it so that the filling can firm up and also all of the lady finger liquid can seep into the sponge.
