Cut your bread into 1.5 inch cubes. Let them sit out at room temperature overnight or until stale and hard like croutons.
600 g stale bread
In a large bowl mix together milk, eggs, cream, sugar, cinnamon, and vanilla.
2 cups milk, 2 large eggs, ¼ cup heavy cream, ¼ cup sugar, 1 tbsp cinnamon, ½ tbsp vanilla
Add the hardened stale bread, mix and let it soak for 5 minutes.
Pour half of the mixture into a baking dish, layer with blueberries, then top with the remaining half of the mixture and top with more blueberries. A baking dish about 10x6 inches will work fine. Keep in mind that the mixture will rise when baked.
1 cup blueberries
Bake at 350F for 40-50 minutes or until toothpick inserted comes out clean. The larger the pan, the shorter amount of time it will take. I used a smaller circular dish which is why it actually took me 50 minutes.
While this bakes, I made a custard
