Prepare the Dough: In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, instant yeast, and salt until combined.
Combine Wet Ingredients: In a separate bowl, mix the melted unsalted butter, warm milk, and the large egg until you achieve a smooth blend.
Create the Dough: Gradually pour the wet mixture into the dry ingredients, stirring with a wooden spoon or spatula until a dough begins to form. Transfer the mixture to a floured surface and knead the dough for about 5-7 minutes until you have a smooth and elastic texture.
Let the Dough Rise: Form the dough into a ball and place it in a greased bowl. Cover with a kitchen towel and set it in a warm place. Allow it to rise for approximately 1 hour, or until it has doubled in size.
Prepare the Filling: While the dough is rising, prepare the apple filling. In a mixing bowl, combine the finely chopped apples, lemon juice, ground cinnamon, brown sugar, all-purpose flour, and ground nutmeg. Toss the ingredients gently until the apple pieces are well coated. Set aside.
Roll Out the Dough: Once the dough has risen, gently punch it down to release any air. On a lightly floured surface, roll the dough out into a rectangle measuring about 18x12 inches.
Fill the Dough: Evenly spread the prepared apple filling across the rolled-out dough, ensuring it covers the entire surface.
Roll and Slice: Starting from one long edge, tightly roll the dough into a log shape. Once rolled, use a sharp knife to slice the log into 12 equal pieces.
Prepare for the Second Rise: Arrange the sliced rolls in a greased 9x13 inch baking dish. Cover the dish with a cloth and allow the rolls to rise again for an additional 30 minutes.
Bake the Rolls: Preheat your oven to 350°F (175°C). Bake the rolls for 25-30 minutes or until they are golden brown and cooked through.
Make the Glaze: While the rolls are baking, prepare the glaze by whisking together the powdered sugar, milk, and vanilla extract in a small bowl until smooth and creamy.
Finish and Serve: Once the rolls are finished baking, take them out of the oven and allow them to cool for about 5 minutes. Drizzle the prepared glaze generously over the warm rolls.
Notes
Serve these delightful cinnamon rolls on a decorative platter, drizzle additional glaze on top for a tempting finish, and garnish with thin apple slices or a light dusting of cinnamon to elevate the presentation.
