Begin by cutting each slice of bread into sticks or strips, typically about 1 inch wide. This will be the shape of your French toast sticks.
In a mixing bowl, whisk together the eggs, milk, sugar, vanilla extract, and ground cinnamon until well combined. This creates the custard mixture for your French toast sticks.
Heat a non-stick skillet or frying pan over medium-high heat. Add a small amount of cooking oil or butter to coat the bottom of the pan.
Dip each bread stick into the egg mixture, ensuring that all sides are coated evenly. Allow any excess mixture to drip back into the bowl.
Place the coated bread sticks onto the hot skillet. Cook for about 2-3 minutes on each side, or until they turn golden brown and crispy.
Remove the French toast sticks from the skillet and place them on a plate lined with paper towels to absorb any excess oil.
Serve your French toast sticks while they’re still warm, with a side of maple syrup or your favorite dipping sauce.
