Creating Classic Malvern Apple Custard Pudding can be straightforward if you follow these simple steps:

1. Preheat the Oven: Set your oven to 350°F (175°C) and grease a baking dish with butter.
2. Prepare the Apples: Peel, core, and slice the apples into thin wedges. Arrange them evenly in the bottom of the greased baking dish.
3. Make the Custard Mixture: In a medium bowl, whisk together the milk, eggs, sugar, vanilla extract, flour, salt, and cinnamon (if using) until well combined.
4. Pour the Custard: Carefully pour the custard mixture over the arranged apple slices in the baking dish.
5. Bake: Place the baking dish in the preheated oven and bake for 45-50 minutes, or until the custard is set and a golden top forms.
6. Cool: Once baked, remove the pudding from the oven and let it cool for 15-20 minutes before serving.
7. Serve: Cut into portions and serve warm or at room temperature.
