Preheat a griddle or large skillet over medium heat on the stove.
Put eggs in a shallow bowl. Add milk and vanilla. Mix well with a fork.
Coat the griddle or skillet with nonstick cooking spray.
Dip both sides of bread, one slice at a time, in egg mixture and cook on hot griddle or frying pan.
Cook on one side until golden brown. Turn bread over to cook the other side. It will take about 4 minutes on each side. If using cinnamon, sprinkle it on top. If using syrup, spread on cooked French toast
