Melt 1 tbsp butter in pan on medium heat.
In a mixing bowl, whisk together eggs, milk, vanilla extract, and cinnamon.
Soak both sides of each bread slice in the egg mixture until it has absorbed some of the liquid (about 10 seconds per side).
Place 2 slices at a time (or as many will fit) onto the pan.
Cook french toast on both sides until golden and crispy. Repeat with remaining slices, if necessary.
Serve toast with butter and maple syrup, or any other desired toppings such as fresh fruit or powdered sugar.
