Add the milk, eggs, vanilla and sugar to a wide shallow bowl and whisk until well combined.
Soak the bread slices in this mixture for 2 minutes on each side. You might have to do this in 2 batches depending on the size of your frying pan.
Heat a frying pan with some oil and cook the bread for about 2-3 mins on each side over medium heat until golden.
Serve the French toast warm with some maple syrup and fruit.
Notes
Most French toast recipes have at least one more egg to this amount of milk so feel free to add more eggs as required. You can also add in other spices to your taste.
