Add the sugar to the berries and let them sit or 30 minutes to an hour while the cream cheese softens.
Smear 6 slices of bread with the softened cream cheese, place into a greased foil pan, and top with half of the mixed berries. Repeat once and top with the last of the bread.
Whisk eggs and milk together and pour over the layers of bread.
Next, cover with foil and weigh the whole thing down with cans to compress it so that the French toast is easier to cut and serve.
The next morning, set the over to 350 and pop in the dish. It should be covered for 40-50 minutes then uncovered for 10 or until the top is browned.
