Brioche French toast meets tiramisu in this stunning dessert by Guillaume Marinette: golden slices of buttery brioche, a cloud of whipped mascarpone cream, a dusting of cocoa, and a silky coffee custard poured right over the top. It serves 4 people, and the whole thing is far simpler to pull off than it looks.
Brunch tables rarely get this kind of treatment. Most of the time, French toast is French toast, and tiramisu is tiramisu. But this hybrid recipe refuses to pick a side, borrowing the golden, custardy warmth of one classic and the espresso-soaked elegance of the other. The result is a dessert that feels restaurant-worthy without demanding restaurant-level technique.
If you love quick dessert ideas that don't require hours in the kitchen, this one belongs in your regular rotation.
The brioche French toast tiramisu recipe starts with a great coffee custard
The backbone of this dish is a coffee-infused crème anglaise, and it's what separates this recipe from a simple French toast with whipped cream. Guillaume Marinette builds it from scratch using 25 cl of whole milk, 3 egg yolks, 40 g of sugar, and 1 stick of instant coffee (or one well-pulled espresso shot as an alternative).
How to make the coffee crème anglaise
The process is classic but demands attention. Heat the milk with the coffee until it just begins to steam. In a separate bowl, whisk the egg yolks with the sugar until the mixture turns pale and slightly thick. Then, slowly pour the hot coffee milk over the yolk mixture while stirring continuously. Return everything to the saucepan over low heat, stirring without stopping until the custard coats the back of a spoon. That's the sign it's ready. Pull it off the heat and let it chill in the refrigerator.
This coffee custard is what gets poured over the finished plate, transforming the dessert from a simple brunch dish into something genuinely indulgent. The bitterness of the espresso cuts through the richness of the mascarpone beautifully.
The crème anglaise can be made the night before and kept refrigerated. It will thicken slightly as it cools, which is perfectly normal.
The mascarpone tiramisu cream is the real showstopper
While the custard chills, the tiramisu element comes together with minimal effort. 150 g of mascarpone, 15 cl of heavy cream (kept very cold), and 30 g of powdered sugar go into a bowl and get whipped together until the mixture is firm and smooth. That's the entire mascarpone cream. No eggs, no elaborate layering, no overnight setting time.
Why the cream temperature matters
The heavy cream must be very cold before whipping. This is not optional. Cold cream traps air more efficiently, giving you a stable, spoonable texture that holds its shape when piped onto the warm brioche. If the cream is even slightly warm, it won't mount properly, and the whole thing risks turning into a runny mess on the plate.
This whipped mascarpone filling is what gives the dish its tiramisu identity. It's rich, lightly sweet, and has that distinctive creamy density that makes the Italian classic so beloved. Think of it as a deconstructed tiramisu cream, sitting proudly on top of golden brioche rather than hidden between layers of soaked ladyfingers. For another take on custard-based desserts, the homemade pastry custard tart follows a similar logic of building richness from a few well-chosen ingredients.
Choosing the right brioche makes all the difference
This is not the moment for pre-sliced sandwich brioche. Guillaume Marinette specifically recommends a Vendéenne or Nanterre-style brioche, cut into 4 thick slices. The thickness is what allows the brioche to absorb the soaking mixture without falling apart in the pan. Thin slices will disintegrate. Thick ones hold their structure, develop a golden crust on the outside, and stay soft and custardy on the inside.
The soaking mixture and cooking method
The French toast soak is simple: 2 whole eggs, 20 cl of milk, and 20 g of vanilla sugar, whisked together. Each slice of brioche gets submerged in this mixture until well coated. Then it goes into a hot pan with 20 g of butter, cooked for a few minutes on each side until deeply golden.
Butter, not oil. The fat in the butter browns and adds a nuttiness that complements the coffee and mascarpone without competing with them. And if you have the time and inclination, making the brioche from scratch will give you the best possible result. A homemade loaf, still slightly enriched from the butter worked into the dough, absorbs the egg mixture differently than a store-bought version and holds together even better during cooking.
Always cut thick slices of brioche — at least 2 to 3 cm — for French toast. Thinner slices lose their structure during soaking and cooking.
Plating the tiramisu French toast
Assembly is where this dish becomes visual. The warm, golden brioche slice goes down first. Then the mascarpone cream gets piped or spooned on top in a generous mound. A dusting of unsweetened cocoa powder goes over everything, exactly as it would on a traditional tiramisu. And finally, the cold coffee crème anglaise gets poured around and over the plate.
portions from one batch — perfect for a brunch table or a dinner party dessert
The contrast of temperatures and textures is the whole point: warm brioche, cold cream, silky custard, a slight crunch of cocoa. Every component plays its role. This is the kind of dessert that looks like it took hours but actually comes together in a logical sequence of straightforward steps. If you enjoy creative two-in-one dessert combinations, this hybrid recipe follows the same satisfying logic: why settle for one classic when you can have both?
The dish works equally well as a brunch centerpiece or a plated dessert at the end of a dinner. Served to guests, it reads as sophisticated. Made on a slow Sunday morning, it's pure comfort. Either way, once the coffee custard hits the plate, there's very little left to say.
