In a spacious mixing bowl, combine the eggs, milk, vanilla extract, ground cinnamon, sugar, and a pinch of salt. Use a whisk to blend the ingredients thoroughly until the mixture is smooth and well integrated.
Cut each slice of bread into thick sticks, about 1 inch wide, creating finger-sized pieces that will be easy to dip and cook.
Place a large skillet or griddle over medium heat. Add the butter or coconut oil, allowing it to melt and evenly coat the surface of the pan.
Take each bread stick and dip it into the egg mixture. Let it soak briefly, ensuring it absorbs the mix without disintegrating.
Arrange the soaked bread sticks in the preheated skillet. Allow them to cook for 2-3 minutes on each side, turning them once they are golden brown. Keep an eye on the heat, adjusting as necessary to avoid burning.
Once the French toast sticks are cooked to a golden perfection, remove them from the skillet and place them on a paper towel-lined plate. This will help remove any excess butter or oil.
Before serving, generously dust the sticks with powdered sugar and drizzle warm maple syrup over them for added sweetness.
