01 - Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.
02 - In a small bowl, combine the softened butter, light brown sugar, ground cinnamon, and vanilla extract until thoroughly mixed. Incorporate the finely diced apple, if utilizing.
03 - Distribute the cinnamon-sugar mixture evenly across each flour tortilla, maintaining a 1/2-inch border around the edges.
04 - Tightly roll each tortilla into a wrap. Place the rolled wraps seam-side down onto the prepared baking sheet.
05 - Brush the tops of the wraps with melted butter. Sprinkle generously with the mixture of granulated sugar and ground cinnamon.
06 - Bake in the preheated oven for 12 to 15 minutes, or until the wraps achieve a golden hue and exhibit a slight crispness.
07 - Allow the wraps to cool for a few minutes before serving. They are best enjoyed warm or at room temperature.
