Step 1

Whisk together eggs, milk, sugar, and salt (as well as the optional vanilla extract and cinnamon, if using) in a medium shallow bowl until the mixture is fluffy and light in color.

Step 2

Melt 1 tablespoon butter in a large skillet over medium-high heat. Working with one bread slice at a time, soak the bread in the egg mixture for 3 to 4 seconds per side. Don't let the slices sit too long; they will turn soggy and fall apart.

Step 3

Once butter is melted and bubbling, add 3 soaked bread slices to hot pan and cook until golden brown, or about 1 1/2 to 2 minutes. (There may be some spots that do not brown; that's normal.)

Step 4

Flip each slice, and cook until gold brown, or about 1 1/2 to 2 minutes. Repeat with remaining butter and egg-soaked bread. Serve hot with toppings of choice.
