In a small bowl add condensed milk, salt, and cinnamon stir until smooth. Beat the eggs and vanilla in a wide shallow dish. Next, whisk in the cinnamon mixture into the eggs until the color is even.

Place a griddle over medium heat and add enough butter to coat the surface. Soak 2-4 slices of bread into the egg mixture for about 5-10 seconds on each side. Put the soaked bread onto hot griddle and cook through until golden brown on both sides, about 3 mins per side. Be careful with the heat, adjusting as needed to avoid burning. Repeat until all of the bread has been cooked, serve with fresh fruit or any desired toppings!
