Prepare the Dough: In a large mixing bowl, whisk together all-purpose flour, granulated sugar, salt, and instant yeast. Cut in the cold butter until the mixture resembles coarse crumbs. Gradually stir in milk and the beaten egg until combined, forming a soft dough.

Chill the Dough: Gather the dough into a ball, wrap it in plastic wrap, and refrigerate for at least 30 minutes to make it easier to roll out and create flaky layers.

Make the Filling: While the dough chills, peel, core, and dice your preferred apples. Combine the diced apples with cinnamon and nutmeg in a bowl, mixing thoroughly.

Shape the Kringle: Preheat your oven to 375°F (190°C). Roll out the chilled dough into a large oval shape, about ¼ inch thick. Spoon the apple filling down the center, fold the sides over the filling, and pinch the edges to seal.

Bake: Transfer the kringle to a lined baking sheet and let it rest for about 10 minutes. Bake for 25-30 minutes, or until golden brown.

Glaze: Allow the kringle to cool slightly, then mix powdered sugar and vanilla extract. Drizzle the glaze over the warm kringle.

Serve: Let the kringle cool to room temperature or serve warm. Slice and enjoy.
