Lightly grease a 9x13-inch baking dish with non-stick cooking spray. Set aside.
Prepare the French toast mixture: In a large bowl or deep baking dish, whisk together the milk, heavy cream, eggs, sugar, melted butter, extracts and ¼ teaspoon salt.
Dip bread: Dip each slice of bread into the milk and egg mixture, turning over, until fully coated.
Prepare the casserole: Transfer the dipped bread slices to the prepared baking dish, arranging the bread in 2 overlapping rolls standing upright. Pour the remaining milk and egg mixture evenly over the bread.
Add berries: Tuck 1 cup of the strawberries in between the bread slices. Sprinkle the remaining cup of strawberries over the top of the casserole. Cover the dish tightly with plastic wrap and refrigerate for at least 1 hour, or up to overnight.
Prepare the streusel: In a medium bowl, whisk together the walnuts, flour, both sugars and ¼ teaspoon salt. Drizzle in the melted butter and stir with a fork until both large and small chunks of streusel are formed. Set aside.
Preheat oven: When ready to bake, remove the French toast from the refrigerator and set on the counter while you preheat the oven to 375 degrees F.
Add streusel to top: Sprinkle the streusel evenly over the top of the bread.
Bake for 55-60 minutes or until puffed and golden. Loosely tent the top of the baking dish with aluminum foil during the last 15-20 minutes of baking if the top is browning too quickly.
Serve: Remove the casserole from the oven and allow to cool slightly. Dust with confectioner’s sugar, sprinkle with more berries and drizzle with maple syrup. Enjoy!
