In a large mixing bowl, whisk together 1 cup of all-purpose flour, 2 tablespoons of sugar, and a pinch of salt. In a separate bowl, blend 1 large egg with 1 cup of milk, 2 tablespoons of melted unsalted butter, and 1 teaspoon of vanilla extract until smooth. Gradually pour the wet mixture into the dry ingredients, whisking until you achieve a smooth batter. Allow the batter to rest for about 10 minutes.

Heat a non-stick skillet over medium heat and lightly grease it with butter. Once hot, pour approximately 1/4 cup of the batter into the skillet, swirling to ensure an even layer. Cook for 1-2 minutes, until the edges begin to lift and the surface is set. Carefully flip the crepe and cook for another 30 seconds until both sides are golden brown.

In a separate pan, melt 2 tablespoons of butter over medium heat. Once melted, add 2-3 peeled and thinly sliced apples, along with 1 teaspoon of ground cinnamon and 2 tablespoons of brown sugar. Stir well, cooking for 5-7 minutes until the apples are soft and caramelized.

To assemble your Cinnamon Apple Crepes, place a warm crepe on a plate and spoon a generous amount of the caramelized apple filling in the center. Carefully fold the sides of the crepe over the filling or roll it up.

For a special finishing touch, dollop some whipped cream on top of each assembled crepe. Serve warm.
