Ingredients

The backbone of this bake is sturdy, buttery brioche that absorbs the custard without falling apart. Dark chocolate and hazelnut spread lend richness, while milk, eggs, and a touch of cream create a silky custard base. A few pantry staples—vanilla, cinnamon, and a pinch of sea salt—round out the flavor profile, and toasted hazelnuts add a satisfying crunch at the finish.

Bread & Custard

  • 1 loaf (about 10‑12 slices) brioche bread, thick‑cut
  • 4 large eggs
  • 1 ½ cups whole milk
  • ½ cup heavy cream

Chocolate‑Hazelnut Mix

  • ½ cup dark chocolate chips (70% cacao)
  • ¼ cup hazelnut spread (e.g., Nutella)
  • 2 tablespoons unsalted butter, melted

Seasonings & Garnish

  • 1 teaspoon pure vanilla extract
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon fine sea salt
  • ⅓ cup toasted hazelnuts, roughly chopped

Each component plays a purpose: the brioche provides a buttery canvas, while the egg‑milk custard binds everything together into a silky interior. Dark chocolate delivers depth, and hazelnut spread adds a creamy, nutty sweetness that complements the chocolate’s bitterness. The vanilla, cinnamon, and sea salt amplify the flavors, and the toasted hazelnuts finish the dish with a pleasant crunch and aromatic note.

Step-by-Step Instructions

Preparing the Bread

Slice the brioche into 1‑inch thick pieces and arrange them in a single layer inside a greased 9‑x‑13‑inch baking dish. If you prefer a softer interior, lightly toast the slices for 5 minutes at 350°F; this creates a slightly crisp edge that helps the custard cling without making the bread mushy.

Making the Chocolate‑Hazelnut Custard

  1. Combine wet ingredients. In a large bowl whisk together 4 large eggs, 1 ½ cups whole milk, ½ cup heavy cream, 1 teaspoon vanilla, ½ teaspoon cinnamon, and ¼ teaspoon sea salt until the mixture is uniform and slightly frothy.
  2. Melt chocolate and hazelnut blend. Place ½ cup dark chocolate chips, ¼ cup hazelnut spread, and 2 tablespoons melted butter in a microwave‑safe bowl. Heat in 20‑second bursts, stirring between each, until smooth and glossy. This creates a silky chocolate‑hazelnut emulsion.
  3. Incorporate the emulsion. Pour the melted chocolate mixture into the egg‑milk mixture, whisking constantly to prevent curdling. The custard should turn a deep, velvety brown with a glossy sheen.
  4. Soak the bread. Slowly pour the custard over the arranged brioche, allowing each slice to absorb the liquid for about 2‑3 minutes. Gently press the slices with a spatula to ensure even saturation without breaking the bread.

Baking & Finishing

Preheat the oven to 375°F (190°C). Cover the baking dish with foil and bake for 20 minutes, then remove the foil and continue baking for another 15‑20 minutes, or until the top is set, lightly browned, and a knife inserted in the center comes out clean. Once out of the oven, let the bake rest for 5 minutes, then sprinkle ⅓ cup toasted hazelnuts over the top for crunch. Serve warm, optionally drizzling extra melted chocolate or a dusting of powdered sugar.

Tips & Tricks

Perfecting the Recipe

Use day‑old brioche. Slightly stale bread absorbs more custard without disintegrating, giving you a creamy interior and a firm edge.

Don’t over‑mix the custard. Over‑whisking can incorporate too much air, leading to a spongy texture rather than a silky one.

Cover with foil for the first half. This traps steam, ensuring the bread cooks evenly before the top caramelizes.

Flavor Enhancements

Add a tablespoon of espresso powder to the custard for a subtle coffee note that deepens the chocolate flavor. A pinch of orange zest brightens the richness, while a drizzle of salted caramel after baking introduces a pleasant salty‑sweet contrast.

Common Mistakes to Avoid

Avoid soaking the bread for more than 5 minutes total; excess liquid can make the bake soggy. Also, don’t bake at a temperature higher than 375°F, as the custard may set before the top develops that coveted caramelized crust.

Pro Tips

Finish with a butter glaze. Melt a tablespoon of butter with a splash of maple syrup and brush over the top during the last 5 minutes for extra shine.

Use a kitchen torch. If you prefer a quicker caramelized finish, torch the surface after baking for a few seconds until golden.

Season the hazelnuts. Toss chopped hazelnuts with a pinch of sea salt and a dash of smoked paprika before sprinkling them on top for a subtle smoky edge.

Variations

Ingredient Swaps

Replace brioche with challah or thick‑cut sourdough for a slightly different texture. Swap dark chocolate for milk chocolate if you prefer a sweeter profile, or use white chocolate with toasted almond butter for a pastel twist. Fresh berries can be layered between bread slices for a fruity surprise.

Dietary Adjustments

For a gluten‑free version, use certified gluten‑free bread or a sturdy gluten‑free cake. Substitute dairy milk with almond or oat milk, and use coconut cream in place of heavy cream for a dairy‑free alternative. Vegan bakers can replace eggs with a flax‑seed “egg” mixture and use a vegan hazelnut spread.

Serving Suggestions

Pair the bake with a dollop of lightly sweetened Greek yogurt or vanilla‑flavored ricotta for tangy balance. A side of fresh orange segments or a simple mixed‑green salad dressed with citrus vinaigrette brightens the plate. For a truly indulgent brunch, serve alongside chilled mimosas or a robust cold brew.

Storage Info

Leftover Storage

Allow the bake to cool completely, then cut into individual portions and store them in an airtight container. Refrigerate for up to 3 days. For longer keeping, wrap portions tightly in plastic wrap, then foil, and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating Instructions

Reheat in a pre‑heated 350°F oven, covered with foil, for 10‑12 minutes, then uncover for an additional 3‑4 minutes to restore the caramelized top. Microwaving works in a pinch: 30‑second bursts on medium power, adding a splash of milk if the slice looks dry.

Frequently Asked Questions

Absolutely. Prepare the custard, soak the bread, and cover the dish tightly before refrigerating overnight. This allows the flavors to meld and saves you time in the morning—just pop it in the oven and bake.

Substitute with any nut butter (almond, cashew) mixed with a tablespoon of cocoa powder and a touch of maple syrup. The flavor will shift, but you’ll still get a creamy, nutty base that pairs beautifully with the chocolate.

Cover the dish with foil for the first 20 minutes of baking; this traps moisture. Remove the foil for the final 10‑15 minutes to achieve a golden, caramelized crust without drying out the interior.

This Decadent Chocolate Hazelnut French Toast Bake brings together the comfort of classic French toast with the elegance of a chocolate‑hazelnut dessert. You now have every detail—from ingredient selection to storage—so you can recreate it confidently any day of the week. Feel free to experiment with swaps, toppings, or presentation to make it truly yours. Serve warm, savor each bite, and enjoy the luxurious start to your morning!
