Cut each slice of bread into 4 equal strips. Set aside. In a large bowl, whisk together eggs, whipping cream, milk, vanilla, sugar and cinnamon. In a large saucepan over medium heat, melt butter. After butter is melted, dip each piece of bread in egg mixture, let excess drip off and place in saucepan. Don’t place too many pieces of bread in the pan so it is overcrowded. Once one side is golden brown, flip over and cook the other side until golden brown and crispy on the outside. Sprinkle with powdered sugar and serve with maple syrup.
