Follow these simple steps to create your delicious Blueberry Bread Pudding:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish.
2. Prepare Bread: In a large bowl, combine the cubed stale bread and blueberries gently. Place them in the greased baking dish evenly.
3. Mix Custard: In a separate bowl, whisk together the eggs, milk, heavy cream, sugar, vanilla extract, cinnamon, and salt until well combined.
4. Combine Mixtures: Pour the custard mixture over the bread and blueberries, ensuring that all the bread is soaked.
5. Let It Soak: Allow the mixture to sit for about 15-20 minutes to let the bread absorb the custard.
6. Bake: Place the baking dish in the preheated oven and bake for 45-50 minutes, or until the top is golden brown and a knife inserted in the center comes out clean.
7. Cool: Remove from the oven and let it cool for about 10-15 minutes before serving.
8. Serve: Dust with powdered sugar if desired and enjoy warm.
