Creating Nutella Bread Pudding is simple if you follow these easy steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish.
2. Prepare the Bread: Cut the bread into cubes, roughly 1-inch in size. Place the bread cubes into the greased baking dish.
3. Mix the Custard: In a large mixing bowl, whisk together the eggs, whole milk, granulated sugar, vanilla extract, salt, and ground cinnamon until well combined.
4. Add Nutella: Gently fold in the Nutella into the custard mixture until fully incorporated. You can leave some swirls for an aesthetic touch.
5. Combine with Bread: Pour the custard mixture over the bread cubes. Gently press the bread down to ensure it absorbs the liquid.
6. Let It Sit: Allow the mixture to sit for about 10-15 minutes. This helps the bread soak up the custard.
7. Bake: Place the baking dish in the preheated oven and bake for 45-50 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
8. Cool: Remove from the oven and let it cool for about 10 minutes before serving. This cooling time helps the pudding set.
9. Dust with Powdered Sugar: If desired, dust the top with powdered sugar for a decorative finish.
