Panettone French Toast (Rabanada)

Slice the panettone.

Beat the egg in a shallow dish.

Dip the panettone slices into the beaten egg, making sure to coat both sides.

Melt the butter in a skillet.

Fry the panettone slices in the skillet with the melted butter until golden brown on both sides.

Remove the slices from the skillet and place them on a plate.

Sprinkle sugar and cinnamon over the slices.
