Step 1
Combine the egg, sugar and flour in a medium bowl. Gradually add the milk, stirring constantly, until well combined and mixture is smooth. Set aside for 30 mins to rest.
Step 2
Heat a 15cm (base measurement) non-stick frying pan over medium heat. Brush with melted butter. Pour about 1 tbs of batter into the pan and swirl to coat. Cook for 1 min or until lightly golden and just set. Use a spatula to turn and cook for a further 30 seconds or until golden. Transfer to a plate. Repeat to make about 24 crepes.
Step 3
To make the tiramisu filling, stir the coffee and water in a medium bowl until the coffee dissolves. Add the mascarpone, icing sugar and marsala. Stir until well combined. Whisk until mixture thickens slightly.
Step 4
To make the Nutella filling, combine the Nutella, chocolate and mascarpone in a medium bowl. Whisk until mixture thickens slightly.
Step 5
Place 1 crepe on a serving plate. Spread with a little of the tiramisu mixture. Top with another crepe. Spread with a little Nutella filling. Continue layering with remaining crepes and alternate layers of tiramisu filling and Nutella filling. Place in the fridge for 1 hour or until firm.
