Creating Wild Berry Bread Pudding Drizzled with Orange Sauce is simple when you follow these steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or cooking spray.

2. Prepare the Bread: In a large bowl, combine the cubed bread and mixed wild berries. Toss gently to combine, ensuring the berries are evenly distributed.

3. Make the Custard Mixture: In another bowl, whisk together the eggs, whole milk, heavy cream, sugar, vanilla extract, cinnamon, salt, and orange zest until smooth.

4. Combine: Pour the custard mixture over the bread and berry mixture. Gently press the bread down to ensure it absorbs the liquid evenly. Let it sit for about 15 minutes to allow the bread to soak up the custard.

5. Bake: Transfer the mixture to the prepared baking dish. Bake in the preheated oven for 45-50 minutes or until the top is golden brown and a toothpick inserted in the center comes out clean.

6. Prepare the Orange Sauce: While the pudding is baking, whisk together the powdered sugar and freshly squeezed orange juice in a small bowl until smooth. Adjust the consistency as needed.

7. Cool: Once the bread pudding is done, remove it from the oven and let it cool for about 15 minutes before serving. Drizzle the orange sauce over each serving.
