Arrange the bread and the berries in a 2 1/2 to 3 quart baking dish. Try to even out the berries and get some down in between the slices of bread.
Whisk together 1/2 cup of the sugar and 1 teaspoon of the cinnamon and the salt in a large bowl. Add the eggs, milk and vanilla extract, continuing to whisk until combined.
Pour egg mixture evenly over the bread and berries. Press down to submerge the bread even more.
Let sit on the counter for an hour or refrigerate for up to one day.
Preheat the oven to 350.
Mix together the rest of the cinnamon and sugar and sprinkle evenly over the top.
Bake until puffy and golden brown, about 60 minutes. If it starts to get too brown, cover loosely with foil.
Remove from the oven and let stand for ten minutes before serving.
I used Brioche bread, challah would also be good and if you wanted to make it a little healthier you could use whole wheat. I used raspberries and blackberries, your favorite fruit would work. If using pears or apples, peel and core before slicing.
