Whisk the eggs in a bowl until frothy.
Add milk, vanilla extract, sugar, and salt. Mix well.
Preheat a skillet over medium heat and add butter.
Dip each slice of bread in the egg mixture, soaking briefly.
Place soaked slices on the skillet once butter is melted.
Cook until golden brown, about 3-4 minutes per side.
Repeat with remaining slices, adding more butter as necessary.
Serve warm, topped with maple syrup and fresh berries.
Optionally, dust with powdered sugar before serving.
