Make 2 cups of espresso or strong coffee and let it cool completely.
Pour the cold heavy cream into a large chilled mixing bowl and then add half of the powdered sugar. Now, use an electric mixer to whip the cream until it forms stiff peaks and becomes fluffy whipped cream.
In a different large bowl, whip the cold mascarpone cheese together with the other half of the powdered sugar until it’s a smooth and creamy consistency.
Gently fold the whipped cream into the mascarpone mixture with a rubber spatula. Do not overmix.
Transfer the mascarpone filling into a piping bag for easier assembly. You can also use a spoon to spread the cream.
Pour the cold espresso into a shallow bowl. Then dip half of the ladyfingers, one at a time, into the liquid and place each one in a single layer on the bottom of a deep 8” dish. You may need to break some of the cookies in half to cover the entire surface.
Pipe half of the mascarpone cream on top of the ladyfingers in the dish.
Repeat the process by adding another layer of coffee dipped ladyfingers followed by another layer of mascarpone cream.
Dust the top layer with cocoa powder.
Place the tiramisu in the refrigerator to chill for 15-20 minutes before serving. This gives the dessert time to set and the flavors to meld.
