Dough
- In a large bowl, mix together flour and butter, using a pastry blender, fork or by hand to break the butter into pea size pieces. (food processor could also be used) Add powdered sugar, baking powder, salt, vanilla, egg yolk, sour cream and lemon zest. Bring the dough together using your hands and transfer to a flat surface and knead dough until smooth, about 4 minutes. Divide the dough equally into 2 balls, cover with plastic wrap and refrigerator for 30 minutes.
Apple layer
- In a large bowl, mix together shredded apples, sugar, lemon juice and cinnamon. Squeeze and drain the juice from the apples using your hands or place in a colander.
- Preheat to 350°F. Grease and flour 8 x 8 inch baking pan.
Assemble
- On a lightly floured surface, roll out one part of the dough to the size of the baking pan. Place into the pan, tucking in the sides and corners. Sprinkle 2 tablespoons of ground walnuts over dough. Then spread the apple mixture evenly on the dough, sprinkle another 2 tablespoons of ground walnuts over the apple layer. Roll out the top crust and place over apples, seal the edges and corners, using the tip of a knife, make slits to allow air to escape. Brush with egg wash and sprinkle the remaining walnuts on top.
- Bake for 40 minutes, until the top is lightly browned. Let it cool. Cut into squares and sprinkle with powdered sugar. Enjoy!
