Preheat oven to 350 degrees. Melt the 1-2 inches of butter and using a paper towel, grease your casserole dish.
Cut the bread into one inch strips, place them in the casserole dish overlapping each other.
In a mixing bowl, combine the eggs, milk, heavy whipping cream, vanilla and cinnamon. Pour over the bread.
In a saucepan melt butter, brown sugar, and maple syrup and continue to stir until bubbling. Drizzle over the bread and egg mixture.
Bake in an oven, uncovered for 40 minutes at 350 degrees
