In a mixing bowl, whisk together the eggs, milk, sugar, vanilla extract, and ground cinnamon until well combined. This creates the flavorful custard mixture for your French toast.

Heat a non-stick skillet or frying pan over medium-high heat. Add a small amount of butter or cooking oil to coat the bottom of the pan.

Dip one slice of bread into the egg mixture, making sure to coat both sides evenly. Allow any excess mixture to drip back into the bowl.

Place the coated bread slice onto the hot skillet. Cook for about 2-3 minutes on each side, or until it turns golden brown and slightly crispy.

Repeat the dipping and cooking process for the remaining slices of bread, adding more butter or oil to the pan as needed.

Remove the French toast slices from the skillet and place them on a plate.

Serve your delicious French toast warm, topped with your favorite toppings such as maple syrup, powdered sugar, fresh fruit, or a dollop of whipped cream.
