In a shallow dish, whisk together eggs, milk, maple syrup, vanilla extract, and cinnamon until frothy.

Dip thick-cut slices of bread into the egg mixture, soaking each side for 20-30 seconds.

Heat a skillet over medium heat. Add unsalted butter until melted and bubbling, then cook soaked bread slices for 3-4 minutes on each side until golden brown.

In a separate pan, scramble eggs until fluffy and cook beef bacon or sausage until crispy.

Layer scrambled eggs, crispy bacon or sausage, and cheese between two slices of French toast.

Return the sandwich to the skillet to melt the cheese, if desired.

Cut the sandwich diagonally and serve warm with syrup or condiments.
