Night before serving:
Using 1 tablespoon butter, grease a 21” x 13” x 3.5” disposable aluminum pan.
In a large bowl, combine 16 eggs, 2 cups milk, 6 cups cream, 1/2 cup plus 2 tablespoons granulated sugar, 4 teaspoons vanilla, 1 1/2 teaspoon cinnamon, 1/2 teaspoon ground nutmeg and 1/2 teaspoon salt. Beat with a whisk until blended. Pour mixture over the bread slices. Using a wide flat spatula, mix by gently lifting and rearranging the bread pieces, making sure pieces all are covered evenly.
When ready to bake, preheat oven to 350 degrees F. Spread Praline Topping evenly over the bread, pressing most of it into the spaces between the bread pieces. Bake about 45 - 55 minutes, or until puffed and lightly golden. Custard should be set, but still slightly wet.
