In a small bowl, combine warm milk and warm water, then sprinkle in active dry yeast. Allow the mixture to sit for about 5 minutes until frothy.

In a large mixing bowl, whisk together all-purpose flour, sugar, and salt. Use a pastry cutter to cut in cold butter until the mixture resembles coarse crumbs.

Stir in the yeast mixture and the beaten egg until the dough just comes together. Form into a ball, wrap in plastic wrap, and refrigerate for at least 1 hour.

Roll the dough into a rectangle about 12 inches by 8 inches on a floured surface.

Spoon apple pie filling down the center of the dough and sprinkle cardamom over the filling.

Fold the sides of the dough over the filling, sealing edges tightly, and shape into a ring or horseshoe on a parchment-lined baking sheet.

Preheat oven to 375°F (190°C) and brush the kringle with an egg wash. Bake for 22-25 minutes or until golden brown.

Let the kringle cool for at least 15 minutes. Whisk together powdered sugar, vanilla extract, and enough water to achieve a drizzling consistency. Drizzle the glaze over the kringle.
