In a medium bowl add the cream, mascarpone and powdered sugar, beat on medium / high speed until thickened and creamy. Place in a pastry bag with a large round pastry tip.
Either dip the lady fingers one at a time in a flat bowl containing the coffee or place 3-4 lady fingers (depending on size of cookies) on a plate and spoon the coffee over the cookies.
Form a heart with the mascarpone filling on the coffee soaked lady fingers. Refrigerate at least 3 hours (can also be made the day before). Sprinkle with cocoa before serving. Decorate with chocolate dipped strawberries if desired. Enjoy!
Notes
You can add an egg if you choose. Italians believe the egg helps give the filling the creamy soft as a cloud texture.Tiramisu can be made 1 to 2 days in advance and should be stored in refrigerator. Definitely refrigerate the dessert at least 2-3 hours before serving.
Any left over Tiramisu should be refrigerated and never leave the dessert out for more than two hours. It will keep for up to 4 days in total and leftovers should be refrigerated immediately. Tiramisu can be frozen for up to 3 months.
