Overnight Nutella French Toast

Ingredients: 
½ cup maple syrup
6 eggs
2 cups whole milk or heavy cream
1 teaspoon vanilla extract
1 loaf French bread, sliced into 10 slices
Nutella
Butter
Directions:
1.        Preheat oven to 360 degrees. 
2.        Butter a 9×13 inch baking dish. Pour maple syrup on bottom.
3.       In a large bowl, whisk together the eggs, milk or cream, and vanilla extract until somewhat frothy and set aside.
4.       Smear five slices of bread generously with Nutella and top with another slice each to make five sandwiches. Cut each diagonally into quarters.
5.       Soak each quarter in custard mixture for one to two minutes, flipping to coat evenly.
6.       Transfer to the prepared baking dish. Pour the rest of the custard over the top and dot the top with butter. Refrigerate overnight.
7.       Bake for 35 to 40 minutes until golden brown.
