Cut brioche loaf into 1-inch pieces and use half to line a 2 ½ quart baking dish, pressing the bread down into the dish.
In a medium mixing bowl add block of cream cheese and microwave for 60 seconds on high to soften.
Add maple syrup and vanilla to cream cheese and stir until the mixture becomes smooth.
Pour mixture over first layer of bread and use a spatula to ensure an even layer.
Next, sprinkle half the strawberries over cream cheese mixture.
Add remaining bread to dish and press down.
In a large mixing bowl add 6 eggs, milk, heavy cream, and cinnamon. Whisk to combine.
Pour egg mixture into dish. Cover dish and refrigerate for at least 3 hours or overnight.
When you are ready to bake your casserole, preheat oven to 350 degrees Fahrenheit.
Bake for 45 minutes to 1 hour. Baking a little longer results in a firmer less moist French toast.
When finished baking, top with remaining diced strawberries. For extra garnish you can drizzle chocolate syrup over the casserole or powdered sugar is also nice! Enjoy!
