Step 1

Cut the day-old bread into thick slices. This recipe makes enough batter for four 1-inch (2.54-centimeter) thick slices of bread, or six ¾-inch (1.91-centimeter) thick slices of bread.

Step 2

Beat the eggs, vanilla, sugar, and cinnamon. Crack the eggs into a shallow dish, then beat them with a whisk until they turn pale yellow and no streaks remain. Add the vanilla, sugar, and cinnamon, and whisk again.

Step 3

Heat a large nonstick frying pan over medium heat. It you don't have a nonstick pan, grease a regular with about 1 tablespoon (15 grams) of butter or coconut oil. Allow the pan to get hot enough to sizzle a droplet of water.

Step 4

Dip a slice of bread in the batter. Dip first one side, then the other. Hold the bread in the batter for a few seconds to ensure that it is completely soaked. Allow the excess batter to drip back into the dish before proceeding.

Step 5

Add the bread to the pan and let it cook for 2 to 4 minutes on each side. Cook the bread for 2 to 4 minutes, turn it over with a spatula, then cook it for to 4 minutes more. It is ready when it turns golden-brown and crispy.If your pan is large enough, you may be able to fit two slices of bread, but make sure that they are not touching.

Step 6

Transfer the toast to a plate, then cook the rest. Re-grease the pan with butter or coconut oil as needed. Keep the already-made toast warm by covering it with a clean kitchen towel.

Step 7

Serve the French toast. You can serve the toast as-is, or garnish it with some sliced bananas or fresh berries. You can also drizzle some maple syrup over it.
