Prepare the Bread:

Use a rolling pin to flatten each slice of bread.

Make the Filling:

In a small bowl, combine the melted butter, granulated sugar, and ground cinnamon to form a paste.

Fill and Roll the Bread:

Spread a thin layer of the cinnamon-sugar mixture on each slice of flattened bread. Roll up the bread tightly, pressing the seam to seal.

Prepare the Egg Mixture:

In a shallow dish, whisk together the eggs, milk, and vanilla extract.

Coat the Rolls:

Dip each rolled-up piece of bread into the egg mixture, ensuring it is fully coated.

Cook the Rolls:

Heat the butter in a large skillet over medium heat. Place the rolls seam-side down in the skillet and cook until golden brown on all sides, about 2-3 minutes per side.

Serve:

Serve the Cinnamon Roll French Toast Rolls warm, drizzled with maple syrup or dusted with powdered sugar.

Variations
Cream Cheese Filling:

Add a layer of sweetened cream cheese to the bread before adding the cinnamon-sugar mixture for a richer, tangy flavor.

Nutty Delight:

Sprinkle finely chopped nuts, such as pecans or walnuts, over the cinnamon-sugar mixture before rolling up the bread.

Fruit-Filled Rolls:

Add a layer of fruit preserves or fresh fruit slices, such as strawberries or apples, to the bread before rolling.

Chocolate Cinnamon Rolls:

Sprinkle mini chocolate chips over the cinnamon-sugar mixture for a chocolatey twist.

Substitutions
Gluten-Free Option:

Use gluten-free bread to make this recipe suitable for those with gluten sensitivities.

Dairy-Free Version:

Replace the butter with a dairy-free margarine and use almond milk or another plant-based milk.

Low-Sugar Version:

Substitute the granulated sugar with a sugar substitute like stevia or erythritol.

Vegan French Toast Rolls:

Use flax eggs (1 tablespoon ground flaxseed mixed with 3 tablespoons water per egg) instead of eggs and a plant-based milk and butter alternative.
