Ingredients
For the sponge layer
- 200g sponge fingers
- 300ml strong black coffee, cooled
- 2 tbsp coffee liqueur, optional
For the mascarpone cream
- 4 large eggs, separated
- 100g caster sugar
- 500g mascarpone cheese
For finishing
- 2 tbsp cocoa powder, for dusting
- Dark chocolate shavings, optional

How to Make James Martin Tiramisu
- Prepare the oven: This is a no-bake dessert, so no oven is required. Clear space in the fridge and choose a serving dish around 20 x 25cm.
- Mix the egg yolks: Place the egg yolks and caster sugar in a large bowl. Whisk until pale, thick, and creamy.
- Add the mascarpone: Gently fold the mascarpone into the yolk mixture until smooth and fully combined.
- Whisk the egg whites: In a clean bowl, whisk the egg whites to soft peaks. Carefully fold them into the mascarpone mixture to keep it light.
- Prepare the coffee dip: Mix the cooled coffee with the coffee liqueur, if using. Quickly dip each sponge finger into the coffee, making sure they are soaked but not soggy.
- Assemble the layers: Arrange a layer of soaked sponge fingers in the base of the dish. Spoon over half of the mascarpone cream and smooth the surface.
- Repeat and chill: Add another layer of sponge fingers, followed by the remaining cream. Cover and chill in the fridge for at least 4 hours, or overnight for best results.
Tips
Why is my tiramisu runny?
This usually happens if the sponge fingers are over-soaked or the mascarpone mixture is overmixed. Dip the sponges quickly and fold gently.
Can I make this without raw eggs?
You can replace the eggs with 300ml lightly whipped double cream, folded into the mascarpone with the sugar.
How do I get clean slices?
Chill the tiramisu overnight and use a sharp knife wiped clean between cuts.
Serving Suggestions
- Dust generously with cocoa just before serving
- Add dark chocolate shavings for extra richness
- Serve with fresh berries on the side
