1. Prepare the apples: Start by peeling, coring, and finely dicing your two medium apples. Aim for pieces about 1/4 to 1/2 inch in size. Smaller pieces will cook faster and distribute more evenly throughout the fritters.

2. Season the apples: In a medium bowl, combine the diced apples with the granulated sugar, ground cinnamon, and ground nutmeg. Toss gently to ensure the apples are evenly coated with the spice mixture. This step infuses the apples with warm, comforting flavors.

3. Unroll the crescent dough: Preheat your oven to 375 F (190 C). Unroll the can of crescent roll dough onto a clean work surface. Do not separate the individual triangles. Press the seams together gently to form one large rectangle. You can use a rolling pin to lightly flatten it further if desired, ensuring it’s a uniform thickness.

4. Assemble the fritters: Spoon the seasoned apple mixture evenly over the entire surface of the crescent roll dough. Leave a small border around the edges. Carefully roll up the dough from one of the longer sides, creating a log.

5. Slice and bake: Using a sharp knife, slice the log into approximately 12-14 equal pieces, about 1 inch thick. Place these slices cut-side up on a baking sheet lined with parchment paper. Brush the tops of each fritter with the melted unsalted butter.

6. Bake until golden: Bake for 20-25 minutes, or until the fritters are golden brown and the apples are tender. The exact time may vary slightly depending on your oven. Keep an eye on them towards the end to prevent over-browning.

7. Prepare the glaze: While the fritters are cooling slightly, whisk together the powdered sugar, milk (or water), and vanilla extract in a small bowl until smooth. Adjust the consistency by adding more milk or powdered sugar as needed, aiming for a pourable but not too thin glaze.

8. Glaze and serve: Once the fritters are out of the oven and have cooled for a few minutes (they should still be warm), drizzle the glaze generously over them. Serve immediately and enjoy the warm, crispy goodness!
