Making Wisconsin Apple Kringle can be a fun and rewarding experience. Follow these steps to create this delightful pastry:

1. Prepare the Dough: In a large bowl, mix together the flour, baking powder, salt, and granulated sugar.

2. Cut in the Butter: Add the chilled butter and use a pastry cutter or your fingers to mix until the mixture resembles coarse crumbs.

3. Add Wet Ingredients: Stir in egg yolk, vanilla extract, and cold water. Mix until just combined.

4. Chill the Dough: Wrap the dough in plastic wrap and refrigerate for 30 minutes.

5. Make the Apple Filling: While the dough chills, combine the diced apples, cinnamon, brown sugar, raisins (if using), and lemon juice in a bowl. Set aside.

6. Preheat the Oven: Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.

7. Roll Out the Dough: On a floured surface, roll the chilled dough into a rectangle about 1/4 inch thick.

8. Add the Filling: Place the apple mixture in the center of the rolled-out dough, leaving about an inch of space on each side.

9. Fold the Dough: Fold the edges of the dough over the filling, creating a rectangle. Pinch the seams to seal.

10. Bake the Kringle: Transfer the assembled Kringle to the baking sheet. Bake for 30-35 minutes or until golden brown.

11. Cool and Glaze: Remove from the oven and allow to cool for 15-20 minutes. In a small bowl, mix powdered sugar and milk to create a glaze.

12. Drizzle the Glaze: Once cooled, drizzle the glaze over the Kringle and dust with additional cinnamon if desired.

13. Slice and Enjoy: Cut into pieces, and enjoy your homemade Wisconsin Apple Kringle!
