Chocolate Babka French Toast with Mascarpone

Thick slices of chocolate babka are soaked in a rich custard of eggs, cream, and orange zest, then seared on a hot griddle until the chocolate swirls caramelize into golden, crispy edges. Topped with whipped mascarpone, flaky sea salt, and warm chocolate ganache, this is the ultimate brunch flex that turns leftover babka into pure gold.

This chocolate babka French toast is a showstopper brunch dish that transforms leftover babka into something extraordinary. The key is using thick slices—about two inches—so they soak up the custard without falling apart. The custard is enriched with heavy cream and brightened with orange zest, which complements the dark chocolate beautifully.

Searing in clarified butter on a cast-iron griddle gives the exterior a crisp, caramelized crust while keeping the inside tender and moist. Finished with mascarpone, sea salt, and warm ganache, every bite is a balance of rich, sweet, and slightly savory flavors.

Ingredients

Why this recipe works

Soaking the babka in a custard of eggs and heavy cream ensures the interior becomes soft and custardy, while the exterior sears to a crisp golden brown. The orange zest adds a fragrant citrus note that cuts through the richness of the chocolate, preventing the dish from feeling heavy.

Using clarified butter allows for a higher cooking temperature without burning, producing a clean, nutty flavor that enhances the caramelization of the chocolate swirls.

Cooking the French toast on a cast-iron griddle provides even heat and a large surface area, so each slice develops a beautiful crust. The three-minute-per-side cooking time is long enough to set the custard without overcooking the bread, leaving it moist inside.

The final toppings—mascarpone, sea salt, and ganache—add layers of creaminess, crunch, and intense chocolate, making this a truly indulgent brunch experience.

Notes and substitutions

Choose a high-quality chocolate babka with visible chocolate swirls; the darker the chocolate, the more intense the caramelized flavor. If your babka is stale, it will absorb the custard even better, so don't shy away from day-old bread. The custard can be adjusted to your taste—add a pinch of cinnamon or nutmeg if desired, but the orange zest is key to brightening the dish.

For the best texture, use a cast-iron griddle or a heavy-bottomed skillet that retains heat well. Clarified butter is ideal because it won't burn at the high temperature needed for caramelization.

If you don't have clarified butter, use a mix of regular butter and a neutral oil to prevent burning. The mascarpone should be at room temperature for easy spreading, and the ganache should be warm but not boiling.

• chocolate babka: Use brioche or challah with chocolate chips folded in, or a store-bought chocolate babka.
• clarified butter: Regular unsalted butter works, but watch the heat to prevent burning.
• mascarpone: Use whipped cream cheese or crème fraîche for a similar tangy richness.
• orange zest: Omit or replace with 1/2 tsp almond extract for a nutty note.
