Step 1: In a shallow wide bowl or pie dish, whisk the eggs until the yolks and whites are fully combined and no streaks remain.
Step 2: Add the whole milk, granulated sugar, vanilla extract, ground cinnamon, and salt to the eggs. Whisk vigorously until the sugar is dissolved and the cinnamon is distributed.
Step 3: Place a large non-stick skillet or griddle over medium-low heat and add 1 tablespoon of butter, swirling to coat the surface as it melts.
Step 4: Dip two slices of bread into the egg mixture, allowing them to soak for 15-20 seconds per side until saturated but not falling apart.
Step 5: Place the soaked slices into the hot skillet. Cook for 3-4 minutes on the first side until deep golden brown and slightly crisp.
Step 6: Flip the slices carefully and cook for another 3-4 minutes on the second side. Repeat with the remaining slices, adding more butter to the pan as needed.
Step 7: Serve the french toast recipe immediately with your favorite toppings like maple syrup, fresh fruit, or powdered sugar.
