Mara,
Here is the recipe straight from the "Cooking with Mickey around our world" cookbook.

STUFFED FRENCH TOAST
2 servings

2 or 4 slices sourdough bread cut 1-inch thick
1 banana
1/3 cup sugar
1 tsp. cinnamon
1 egg
1/4 cup milk
1/2 tsp. vanilla extract
Oil or shortening for frying
Whipped butter, if desired
Maple syrup, if desired

Depending on the size of the bread slices, cut a 1-inch pocket in one side of each bread slice. Cut bananas in half crosswise, then split each piece lengthwise. Remove peel and stuff 2 pieces in each pocket of bread, again depending on size. If slices are small, use 4 and stuff 1 piece of banana in each pocket. Set aside. Mix sugar and cinnamon. Set aside. Mix egg, milk and vanilla until well blended.

Heat about 4 inches of oil or shortening in a pan to 350°. Dip stuffed bread into egg and milk mixture, soaking a few minutes to penetrate into bread. Fry in hot oil or shortening until lightly browned, turning to brown both sides, about 3 minutes. Drain on paper towels on cake rack. Sprinkle with sugar and cinnamon and serve at once. If desired, spread with whipped butter and serve with Maple syrup.

NOTE: If more servings are desired, double only the amount of bread, bannans, egg milk and vanilla for 4 servings.
