Preheat the oven: Preheat your oven to 350°F (175°C). Lightly grease a small ramekin or oven-safe dish.
Prepare the custard: In a small bowl, whisk together the milk, egg, sugar, vanilla extract, and salt until well combined.
Assemble the bread pudding: Place the bread cubes into the ramekin and sprinkle the chocolate chips throughout. Pour the custard mixture over the bread, pressing gently to ensure all pieces are soaked. Let it sit for 5 minutes
Bake: Bake for 20–25 minutes, or until the top is golden and the custard is set.
Serve: Allow to cool slightly before serving. Enjoy warm, optionally topped with whipped cream, a drizzle of chocolate sauce, or a dusting of powdered sugar.
