Preheat a griddle to 350F. Using a serrated knife slice bread into 1¼ inch slices. Cut into each slice keeping the end attached, and fill with a heap of Nutella, then set aside.
In a medium bowl whisk together milk, cream, eggs, vanilla, sugar, flour, baking powder and cinnamon, and then pour into a shallow dish.
Butter the griddle, and dip each side of the toast into the egg mixture, squeezing it a bit to really soak it in.
Cook french toast until golden on each side, and then serve immediately topped with sliced strawberries and maple syrup.
