In a mixing bowl, whisk together the eggs, milk, vanilla extract, cinnamon, nutmeg, and sugar until well combined and slightly frothy.
Preheat a skillet or frying pan over medium heat and add 1 tablespoon of butter. Allow the butter to melt and bubble but not brown.
Dip each slice of bread into the egg mixture, ensuring both sides are well coated. Let any excess mixture drip off.
Place the coated slices in the skillet and cook for about 3-4 minutes on each side, or until golden brown. Cook in batches if necessary, adding more butter as needed.
Once cooked, transfer the French toast to a plate and keep warm while you cook the remaining slices.
Serve warm, dusted with powdered sugar, and alongside fresh fruit if desired.
For added flavor, incorporate a pinch of salt or a splash of rum into the egg mixture.
Feel free to experiment with different types of bread for varied textures and tastes.
Serve with maple syrup or your favorite topping for extra sweetness.
