Creating a beautiful Tiramisu Crepe Cake is surprisingly straightforward. Just follow these steps:

1. Make the Crepes:
– In a bowl, whisk together the flour, eggs, milk, sugar, and salt until smooth.
– Stir in the melted butter.
– Let the batter rest for about 10-15 minutes.

2. Cook the Crepes:
– Heat a non-stick skillet over medium heat. Lightly grease with butter or oil.
– Pour about ¼ cup of batter into the skillet, swirling to coat the bottom evenly.
– Cook for 1-2 minutes until the edges start to lift. Flip and cook for another 1 minute or until just golden.
– Repeat until all batter is used, stacking the cooked crepes on a plate.

3. Prepare the Filling:
– In a bowl, combine the mascarpone cheese, heavy cream, powdered sugar, and vanilla extract.
– Whip until smooth and fluffy.

4. Assemble the Cake:
– Place one crepe on a serving plate. Brush the top with a mixture of cooled coffee and coffee liqueur (if using).
– Spread a layer of the mascarpone filling over the crepe.
– Continue layering crepes and filling, alternating until all crepes and filling are used, finishing with a crepe on top.

5. Chill the Cake:
– Cover the assembled cake with plastic wrap and refrigerate for at least 2 hours to allow the flavors to meld.

6. Garnish and Serve:
– Before serving, dust the top with cocoa powder and garnish with chocolate shavings if desired.
