In a large, wide bottom bowl, beat eggs, milk, sugar, vanilla, salt, and cinnamon with wire whisk until smooth.
Cook the French Toast:
Heat a large non-stick pan over medium heat. Once hot, melt some butter.
Dip the bread slices into the egg mixture for about 30 seconds, just enough to soak up some of the mixture on each side but don’t soak it for too long.
Immediately, place several bread slices on the greased hot pan and cook for 2 minutes on the first side, and once golden, flip and cook for an additional 2 minutes on the other side. Repeat this process with the remaining bread slices and soaking mixture.
Serve:
Serve the cooked French toast slices with a little butter, banana slices (if using) and syrup on top.
