Why You'll Love This Recipe

Ingredients

This bake shines because every component plays a specific role. Thick‑cut brioche or challah provides a buttery canvas that soaks up the custard without falling apart. The custard itself is enriched with cocoa powder, hazelnut spread, and a hint of vanilla, creating a deep chocolate flavor. Toasted hazelnuts add crunch, while a simple maple‑brown sugar glaze gives the top a caramelized sheen. Together, these ingredients create a harmonious balance of creamy, crunchy, and sweet textures.

Main Ingredients

• 1 ½ lb (≈10) thick‑cut brioche or challah, sliced 1‑inch thick
• 3 large eggs
• 1 ½ cups whole milk
• ½ cup heavy cream

Chocolate‑Hazelnut Custard

• ¼ cup unsweetened cocoa powder
• ¼ cup hazelnut spread (e.g., Nutella)
• 2 tablespoons pure maple syrup
• 1 teaspoon vanilla extract

Hazelnut Chocolate Sauce

• ½ cup heavy cream
• 2 tablespoons unsalted butter
• ¼ cup hazelnut spread
• 2 tablespoons dark brown sugar
• Pinch of sea salt

Seasonings & Garnish

• ¼ cup toasted hazelnuts, coarsely chopped
• Powdered sugar, for dusting (optional)
• Fresh berries, for serving (optional)

Each ingredient has been chosen to amplify the chocolate‑hazelnut theme while keeping the texture perfect. The combination of milk, cream, and eggs creates a custard that’s both silky and sturdy enough to hold the bread together. Hazelnut spread adds natural sweetness and depth, while cocoa powder intensifies the chocolate flavor without bitterness. The sauce, enriched with butter and brown sugar, caramelizes during baking, giving the top a glossy, crackly finish that’s impossible to resist.

Step-by-Step Instructions

Preparing the Bread

Lay the brioche slices in a single layer on a large baking sheet. Lightly toast them in a 350°F (175°C) oven for 5‑7 minutes, just until the edges turn golden. This extra step creates a firmer surface that will absorb the custard without becoming mushy, ensuring each bite holds its shape after baking.

Mixing the Custard

In a large mixing bowl, whisk together 3 large eggs, 1 ½ cups whole milk, and ½ cup heavy cream until fully combined. Add ¼ cup unsweetened cocoa powder, ¼ cup hazelnut spread, 2 tablespoons maple syrup, and 1 teaspoon vanilla extract. Whisk until the mixture is smooth, glossy, and free of lumps. This custard will infuse the bread with chocolate‑hazelnut flavor while keeping it moist.

Assembling the Bake

Arrange the toasted brioche slices in a greased 9‑x‑13‑inch baking dish, overlapping slightly. Pour the custard evenly over the bread, pressing gently with a spatula so each slice is fully saturated. Let the mixture sit for 10 minutes; this allows the bread to soak up the custard, creating a uniform texture throughout the bake.

Baking

1. Preheat the Oven. Set your oven to 375°F (190°C) and let it fully preheat. A steady temperature ensures the custard sets evenly and the top caramelizes without burning.
2. Prepare the Sauce. While the oven heats, combine ½ cup heavy cream, 2 tablespoons unsalted butter, ¼ cup hazelnut spread, 2 tablespoons dark brown sugar, and a pinch of sea salt in a small saucepan. Melt over medium‑low heat, stirring constantly until smooth and glossy.
3. Drizzle the Sauce. Remove the casserole from the oven after the initial 20‑minute bake. Evenly drizzle the warm hazelnut chocolate sauce over the top, allowing it to seep into the edges.
4. Finish Baking. Return the dish to the oven and bake for an additional 15‑20 minutes, or until the center is set and the surface is a deep golden brown with a slight crackle.

Finishing & Serving

Once baked, let the French toast bake rest for 5 minutes. This short cooling period lets the custard finish setting and prevents the sauce from running off the plate. Sprinkle ¼ cup toasted hazelnuts over the top, dust lightly with powdered sugar if desired, and serve alongside fresh berries for a pop of acidity. Cut into squares and enjoy while warm.

Tips & Tricks

Perfecting the Recipe

Flavor Enhancements

For an extra layer of complexity, stir a splash of espresso into the custard or fold in a tablespoon of orange zest. A pinch of cayenne pepper in the sauce adds subtle heat that balances the sweetness. Top with a dollop of whipped mascarpone for a luxurious finish.

Common Mistakes to Avoid

Avoid over‑mixing the custard; vigorous beating can incorporate too much air, leading to a spongy texture. Also, don’t skip the final drizzle of sauce—without it the top will lack the signature glossy crust that defines this dish.

Pro Tips

Variations

Ingredient Swaps

Swap brioche for thick‑cut French toast bread or even cinnamon swirl bread for extra spice. Replace hazelnut spread with almond butter for a different nutty profile, or use dark chocolate chips in the custard for bursts of chocolate texture.

Dietary Adjustments

For a dairy‑free version, substitute whole milk and cream with oat or almond milk and coconut cream, and use a vegan hazelnut spread. To make it gluten‑free, choose certified gluten‑free bread or use a gluten‑free pancake mix as the base.

Serving Suggestions

Pair the bake with a dollop of Greek yogurt or ricotta for tangy contrast. Fresh berries, sliced bananas, or a drizzle of raspberry coulis add brightness. A glass of chilled espresso or a mimosa rounds out a brunch‑ready spread.

Storage Info

Leftover Storage

Allow any leftovers to cool to room temperature, then cover tightly with plastic wrap or transfer to an airtight container. Store in the refrigerator for up to 3 days. For longer keeping, freeze individual portions wrapped in foil and placed in a freezer bag; they’ll retain quality for up to 2 months.

Reheating Instructions

Reheat refrigerated slices in a 350°F (175°C) oven, covered with foil, for 12‑15 minutes until warmed through. For frozen portions, bake at 375°F (190°C) for 20‑25 minutes, removing the foil halfway to re‑crisp the top. A microwave works in a pinch—heat 30‑second bursts, adding a splash of milk to keep it moist.
