What does ube French toast tiramisu taste like?

Imagine a thick slice of caramelized brioche, soaked in a vanilla-hazelnut ube custard, topped with airy mascarpone whipped cream, dusted with pure ube powder and finished with a sweet ube milk pour. The flavor is exactly like a tiramisu, but warm, with a French toast soul: vanilla, white chocolate, toasted hazelnut from the ube, and the richness of mascarpone.

Why brioche instead of regular bread?

Brioche is enriched with butter and eggs, giving it a soft, custard-like crumb that absorbs the ube milk soak without falling apart. Cut thick slices (3 cm minimum) for the proper French toast texture: crisp golden crust outside, soft custardy center inside.

Can I use a different bread?

Yes. Hokkaido milk bread, challah, or pain de mie brioché all work. Avoid sourdough or rustic country bread, the texture is too dense and the flavor competes with the ube. The bread must be slightly stale (one day old) to absorb the soak properly.

How much ube powder do I need?

Around 18g total: 8g in the soak for color and flavor, 10g for the sweet ube milk topping, plus a generous dusting on top of the mascarpone. Pure ube powder gives both the deep purple color and the signature vanilla-hazelnut taste.

Can I make this dairy-free or vegan?

Yes. Use oat milk for the soak, replace the egg with 60g of silken tofu blended smooth, swap mascarpone for whipped coconut cream, and use the oat milk version of the ube topping. The result is slightly lighter but still indulgent.

Why mascarpone whipped cream and not regular whipped cream?

Mascarpone gives the iconic tiramisu mouthfeel: rich, slightly tangy, dense yet airy. Plain whipped cream would feel too light and would slide off the toast. Mascarpone holds its shape, anchors the ube dusting, and balances the sweetness of the bread.

Can I prepare this in advance?

The mascarpone cream and ube milk can be made the day before and kept in the fridge. The French toast itself must be cooked à la minute and served immediately, while the brioche is still warm and the cream stays cold. Assemble at the last moment for the perfect contrast.
