1. Prepare the Cream Mixture:
In a mixing bowl, beat the heavy cream until it reaches a medium consistency (not stiff peaks).
Combine the cream cheese or mascarpone cheese with the heavy cream until well combined.
In another bowl, whisk together the egg yolks, sugar, and water. Microwave the mixture for 30 seconds, then beat it until it turns white and dense.
Using an electric mixer, beat the mixture on medium speed for about 5 minutes until it reaches a dense texture and turns white.
Add the egg yolk mixture to the cream mixture and beat until homogeneous.
2. Assemble the Tiramisu:
Dip each ladyfinger biscuit into the raspberry liqueur and place them in a 9x9-inch baking dish to create a single layer.
Spread half of the cream mixture over the finger ladies, ensuring it cover the entire surface. Then sprinkle half of the frozen raspberries evenly over the cream layer.
Place the rest of the fingerladies over the cream mixture and then spread raspberry jam over them.
Finally, spread the rest of the cream mixture over raspberry jam, ensuring it covers the entire surface.
3. Chill and Serve:
Cover the baking dish with plastic wrap and refrigerate the tiramisu for at least 4 hours or overnight to allow the flavors to meld and the dessert to set.
Before serving, decorate the top with fresh raspberries and dust with powdered sugar if desired. .
Serve chilled and enjoy.
