Creating Cozy Blueberry Bread Pudding is a straightforward process. Follow these simple steps to ensure your dish turns out perfectly:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). This will ensure that the pudding bakes evenly.
2. Prepare the Baking Dish: Grease a 9×13-inch baking dish with unsalted butter to prevent sticking.
3. Cube the Bread: Cut the stale bread into bite-sized cubes and place them evenly in the greased baking dish.
4. Add Blueberries: Scatter the fresh blueberries over the cubed bread, ensuring they are evenly distributed.
5. Whisk Wet Ingredients: In a large bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt until well combined.
6. Combine Mixtures: Pour the egg mixture over the bread and blueberries, gently pressing down to ensure all the bread absorbs the liquid.
7. Let Sit: Allow the mixture to sit for about 15-20 minutes. This helps the bread soak up the custard.
8. Bake: Place the baking dish in the preheated oven and bake for 45-50 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
9. Cool: Once baked, remove the pudding from the oven and let it cool for 10-15 minutes before serving.
10. Dust with Powdered Sugar: For a final touch, dust the top with powdered sugar if desired, adding a beautiful finish to your dessert.
