Prepare the Egg Mixture: In a large bowl, whisk together 12 beaten eggs, 1 cup of milk, ½ teaspoon of cinnamon, 1 teaspoon of vanilla extract, and 3 tablespoons of sugar until well combined and smooth.

Slice the Bread: Cut the loaf of Italian or French bread into thick slices, about 1-inch thick, so they hold up during cooking.

Heat the Pan: Preheat a large skillet or griddle over medium heat. Add a small amount of vegetable oil or butter, just enough to lightly coat the pan.

Dip the Bread: Dip each slice of bread into the egg mixture, making sure to coat both sides evenly. Let any excess mixture drip off before placing the bread in the pan.

Cook the French Toast: Place the coated bread slices in the preheated skillet. Cook for 2-3 minutes on each side, or until golden brown and crispy on the outside. Add more oil or butter as needed between batches.

Serve: Once cooked, transfer the French toast to a plate and serve warm. Top with your favorite toppings like maple syrup, powdered sugar, or fresh fruit.

Enjoy your delicious homemade French toast!
