Creating these amazing Cinnamon Sugar French Toast Roll-Ups is both fun and simple. Follow these steps:

1. Prepare the Bread: Remove the crust from each slice of bread and gently flatten using a rolling pin.
2. Make the Egg Mixture: In a bowl, whisk together the eggs, milk, sugar, vanilla extract, and cinnamon until well combined.
3. Add Filling: Spread your choice of filling evenly across the flattened bread slices, leaving a small border.
4. Roll Up the Bread: Starting from one end, roll each slice tightly and secure with a toothpick if necessary.
5. Heat the Pan: In a large skillet, melt the butter over medium heat.
6. Dip the Rolls: Dip each roll-up into the egg mixture, ensuring they are well-coated.
7. Cook the Roll-Ups: Place the coated roll-ups in the skillet and cook until golden brown on all sides, about 2-3 minutes per side.
8. Make Cinnamon Sugar: In a shallow dish, mix together the granulated sugar and ground cinnamon for rolling.
9. Roll in Cinnamon Sugar: Remove the roll-ups from the skillet and immediately roll them in the cinnamon-sugar mixture while warm.
10. Serve Warm: Plate the roll-ups and remove any toothpicks before serving. Enjoy with maple syrup, fresh berries, or a dusting of powdered sugar.
