Creating your Very Berry Bread Pudding is simple when you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
2. Prepare Bread: In a large mixing bowl, combine the cubed bread and mixed berries. Gently toss to distribute the berries evenly.
3. Mix Wet Ingredients: In another bowl, whisk together the eggs, whole milk, granulated sugar, vanilla extract, and ground cinnamon until well combined.
4. Combine Mixtures: Pour the egg mixture over the bread and berries. Stir gently to ensure all bread pieces are soaked.
5. Let It Sit: Allow the mixture to sit for about 10 minutes, giving the bread time to absorb the custard.
6. Transfer to Baking Dish: Pour the bread pudding mixture into the prepared baking dish, spreading it evenly.
7. Bake: Place in the preheated oven and bake for 40-45 minutes or until the top is golden brown and a knife inserted in the center comes out clean.
8. Cool: Once baked, remove from the oven and let it cool for 10-15 minutes before serving.

Following these steps will lead you to a delightful Very Berry Bread Pudding that is sure to impress.
