Directions

1. Slice the brioche into 1 1/2-inch-thick slices (6 to 8 slices). Lay each slice on its side and cut a 2-inch slit into the bottom of each. Fill the slit with about 1 tablespoon of the chocolate-hazelnut spread.
2. Whisk together the milk, vanilla, salt and eggs in a shallow bowl or baking dish. Place the crushed cereal in another baking dish. Dip a slice of the filled brioche into the egg mixture on both sides a few times, making sure the mixture has soaked in, then transfer to the cereal dish and coat with cereal on both sides. Place the bread on a cutting board or plate while finishing dredging the rest. Repeat with the remaining slices, egg mix and cereal.
3. Heat a large, nonstick skillet over medium heat with 2 tablespoons of the butter. Place as many slices as will fit in the skillet. Cook on one side until the coating is crisp and golden brown, 2 to 3 minutes, then flip and cook another 2 to 3 minutes on the other side. Transfer to a platter. Add 2 more tablespoons of butter to the skillet and then more slices. Repeat the process with the remaining butter and slices, reserving 2 tablespoons of butter for the bananas.
4. Add the remaining butter to the skillet, let it melt and place the bananas in a single layer in the melted butter. Cook until caramelized, 1 to 2 minutes on each side. Top the toast with the bananas and sprinkle with confectioners' sugar. Serve immediately.
