Chocolate Babka French Toast with Mascarpone Step-by-step instructions

Before you start

Before you begin, slice the chocolate babka into 2-inch-thick slabs. If the babka is very soft, freeze it for 15 minutes to make slicing easier. In a shallow dish, whisk together the eggs, heavy cream, vanilla, and orange zest until smooth.

Set the clarified butter in a small pan and have the mascarpone, sea salt, and warm ganache ready for topping. Preheat the griddle over medium heat so it's hot when you're ready to cook.

Instructions

Soak and Heat

1. 1Prepare the Custard and Soak the Babka
   In a wide, shallow bowl, whisk the eggs, heavy cream, vanilla extract, and orange zest until fully combined and smooth. Place the babka slices in the custard and let them soak for 60 seconds per side, turning gently with a spatula to coat evenly. The bread should absorb the custard without becoming soggy.
   Look for The custard is pale yellow and slightly thickened; the babka slices are moist but hold their shape.
   Tip Use a shallow dish so the slices lie flat and soak evenly.
2. 2Heat the Griddle
   Place a cast-iron griddle or large skillet over medium heat and add the clarified butter. Swirl to coat the surface. Heat until the butter shimmers and a drop of water sizzles on contact, but do not let it smoke.
   Look for The butter is melted and shimmering but not browning.
   Tip If using regular butter, add a splash of oil to raise the smoke point.

The custard is smooth and well combined, and the babka slices have absorbed it for 60 seconds per side. The griddle is hot with clarified butter shimmering, but not smoking. The babka slices are moist but hold their shape when lifted.

Sear Until Golden

3. 3Sear the French Toast
   Carefully lay the soaked babka slices on the hot griddle in a single layer. Cook for 3 minutes per side, or until the bottoms are deeply golden and the chocolate swirls begin to caramelize. Flip gently with a spatula and cook the other side for another 3 minutes. Work in batches if needed, adding more butter between batches.
   Look for The edges are crisp, the surface is golden brown with caramelized chocolate streaks.
   Safe temperature 160°F (71°C) internal temperature (egg dishes)
   Tip Press lightly with a spatula while cooking to ensure even browning.
4. 4Check the Internal Temperature
   To ensure the eggs are fully cooked, insert an instant-read thermometer into the thickest part of a slice. The temperature should register at least 160°F (71°C). If not, continue cooking for another minute or two per side until the target is reached.
   Look for The thermometer reads 160°F (71°C) or higher.
   Safe temperature 160°F (71°C) internal temperature (egg dishes)
   Tip If you don't have a thermometer, cut into a slice to check that the custard is set and no raw egg remains.

The French toast has cooked for 3 minutes per side, developing a deep golden-brown crust with caramelized chocolate streaks.

The kitchen smells of toasted bread, butter, and chocolate. The slices are crisp on the outside and set on the inside, with no raw egg visible.

Top and Serve

5. 5Top and Serve
   Transfer the cooked French toast to serving plates. Dollop with mascarpone cheese, sprinkle with flaky sea salt, and drizzle generously with warm chocolate ganache. Serve immediately while hot and crisp.
   Look for The mascarpone is soft, the ganache is glossy and warm, and the salt adds a savory crunch.
   Tip Warm the ganache in the microwave or on the stovetop just until pourable.

The finished French toast is topped with dollops of mascarpone, a sprinkle of flaky sea salt, and a generous drizzle of warm chocolate ganache. The ganache is glossy and slightly runny, and the salt adds a savory crunch. The dish is ready to serve immediately.

Common mistakes

One common mistake is using slices that are too thin, which causes them to become soggy and fall apart. Stick to 2-inch-thick slices for the best texture. Another pitfall is overcrowding the griddle—cook in batches to maintain even heat and ensure proper browning.

Avoid flipping too early; wait until the bottom is deeply golden to get that caramelized crust. Finally, don't skip the orange zest—it balances the richness and prevents the dish from being cloying.

How to tell it’s done

The French toast is done when the exterior is deeply golden and crisp, and the chocolate swirls have caramelized to a glossy, dark brown. The interior should be set—no raw egg visible—and the bread should feel firm but spring back when pressed.

For safety, insert an instant-read thermometer into the center of a slice; it should read at least 160°F (71°C). The edges will be slightly crunchy, while the center remains tender and custardy.
