Preheat the oven to 400F, and spray a 9x9 baking pan with nonstick spray. Set aside.

Place the slices of bread onto a baking sheet, and place in the oven for a few minutes as it pre-heats. When one side of the bread is toasted, flip the slices and toast the other side. If your bread is sufficiently stale/hardened, you can skip the toasting step!

Arrange the sliced bread in a single layer in your prepared pan. I placed mine "sitting up" so all the bread would fit in my pan, and also because I thought the crusty edge on the top would look extra pretty.

In a medium bowl, whisk together the eggs, milk, vanilla, raspberry jam, and powdered sugar, and beat until smooth (the jam will stay in tiny chunks, that's okay!). Pour the mixture evenly over your prepared bread in the pan. Now, grab the raspberries and chocolate chunks, and tuck them in-between the slices of bread. They will seep into the bread as it bakes and make your french toast super yummy! Top with additional chocolate and raspberries if desired.

Cover the pan with aluminum foil, and place in oven for about 60 minutes. Then, remove foil and continue baking for another 20-30 minutes. French toast should be minimally jiggly in the center! Let cool for 15-20 minutes before cutting and serving. Top with extra powdered sugar and serve with more fresh berries!

Pro tip: you can make this the night before, then just reheat in the oven the next morning! :)
