Start by peeling and chopping the apples into small pieces. In a large bowl, whisk together the eggs, milk, ground cinnamon, and brown sugar until well combined.

In a skillet over medium heat, melt 2 tablespoons of butter. Add the chopped apples along with brown sugar and ground cinnamon. Cook for about 5 minutes, stirring occasionally, until the apples soften and become fragrant.

Take each slice of bread and flatten it with a rolling pin. Place a scoop of the warm apple mixture at one end of the bread slice, then carefully roll it up tightly, sealing the filling inside.

Dip each roll-up into the prepared egg mixture, ensuring they are coated thoroughly. Let any excess mixture drip off before moving to the skillet.

In the same skillet, add the remaining butter. Cook the roll-ups seam side down over medium heat. Sauté each side for about 2 minutes until they're golden brown and crispy.

Place the delicious roll-ups on plates, then drizzle them with warm maple syrup or dust them with powdered sugar for an inviting finish.
