Prepare the Bread:

1. Remove the crusts from each slice of bread to create a uniform, soft texture.
2. Using a rolling pin, gently flatten each slice until thin but intact.

Make the Cinnamon-Sugar Filling:

1. In a small bowl, combine the melted butter, brown sugar, and ground cinnamon. Mix until well blended to form a spreadable paste.

Assemble the Roll-Ups:

1. Spread a thin, even layer of the cinnamon-sugar mixture over each flattened bread slice, leaving a small border around the edges.
2. Starting from one end, roll each slice tightly into a log shape. Press gently to seal the edge; if needed, use a dab of the cinnamon-sugar mixture to help it adhere.

Prepare the French Toast Coating:

1. In a shallow bowl, whisk together the eggs, milk, ground cinnamon, and vanilla extract until smooth and well combined.

Cook the Roll-Ups:

1. Heat a non-stick skillet over medium heat and add 2–3 tablespoons of butter, allowing it to melt and coat the pan evenly.
2. Quickly dip each roll-up into the egg mixture, ensuring it is fully coated but not oversaturated.
3. Place the roll-ups seam-side down in the skillet. Cook for 2–3 minutes per side, rotating to ensure all sides are golden brown and the roll-up is heated through.

Serve and Enjoy:

1. Once cooked, remove the roll-ups from the skillet and place them on a serving plate.
2. Dust with powdered sugar, drizzle with maple syrup, or top with cream cheese frosting, caramel drizzle, or whipped cream as desired.
3. Serve immediately and enjoy this sweet, indulgent treat.
