Step 1: Prepare the Cinnamon Sugar - In a small bowl, combine the granulated sugar and cinnamon. Set it aside; this will be your delicious coating for the French toast sticks.
Step 2: Make the Custard Mixture - In a large mixing bowl, whisk together the eggs, whole milk (or nut/seed-based milk), vanilla, maple syrup, freshly grated nutmeg, and kosher salt until well combined.
Step 3: Soak the Bread - Take each slice of bread and cut it into three equal strips. Dip each strip into the egg mixture, ensuring that both sides are well coated but not overly soggy. Allow any excess custard to drip off.
Step 4: Heat the Skillet - In a large skillet or griddle, melt 2 tablespoons of salted butter over medium heat. Swirl the butter around to coat the surface evenly.
Step 5: Fry the Sticks - Place the soaked bread strips in the skillet, making sure not to overcrowd the pan. Fry for about 2-3 minutes on each side, or until golden brown and crispy. Add more butter as needed for subsequent batches.
Step 6: Coat with Cinnamon Sugar - Once the sticks are cooked, immediately toss them in the cinnamon sugar mixture, ensuring they are fully coated. Transfer them to a cooling rack while you repeat the process with the remaining bread.
Step 7: Serve Warm - Serve your Cinnamon Sugar French Toast Sticks warm, with additional maple syrup for dipping and whatever toppings you desire—fresh berries, whipped cream, or even a dusting of powdered sugar.
