In a glass pie dish, whisk together the eggs, milk, vanilla, and salt.
Melt four tablespoons of butter in a large skillet over medium-high heat.
Place a slice of bread into the milk mixture allowing the bread to soak a few seconds on each side.
Shake off excess milk mixture from the bread and place the slices into the hot skillet. Fry the toast until browned on one and flip to brown the other side.
Top the toast with a pad of butter and maple syrup.
