Preheat oven to 425°F (220°C).

Melt butter in a 15 x 10-inch jelly roll pan in the hot oven.

Remove pan from oven and sprinkle the melted butter with a mixture of sugar and cinnamon.

In a separate bowl, mix eggs and orange juice.

Dip each bread slice into the egg mixture until well soaked.

Arrange the soaked bread slices close together in the prepared pan.

Bake for 20 minutes, or until the French toast is set and golden brown.

Invert the French toast onto serving plates.

Serve immediately with hot maple syrup and sifted powdered sugar.
