Flatten each slice of bread with a rolling pin to make them easier to roll up.
In a shallow dish, mix together the granulated sugar and ground cinnamon. Set aside.
Spread each slice of bread with a thin layer of your favorite spread and roll them tightly.
In a mixing bowl, whisk together the eggs, milk, and vanilla extract until well combined.
Preheat a skillet or griddle over medium heat and melt 1 tablespoon of butter.
Dip each rolled bread in the egg mixture, ensuring they are well-coated, then roll them in the cinnamon-sugar mixture.
Place the roll-ups seam side down in the skillet and cook for about 2-3 minutes on each side or until golden brown.
Remove from the skillet and place on a paper towel-lined plate to absorb any excess butter. Repeat the process with the remaining rolls.
Serve warm, drizzled with cream cheese icing or syrup if desired.
