Steps to make Old-Fashioned Apple Slab


Make pastry


Place 2 ½ cups of all-purpose flour with 1 teaspoon of salt, 1 teaspoon of baking powder, 2 tablespoons of confectioners' sugar and 2 tablespoons of buttermilk powder in a large bowl and mix together. Work in ¼ cup of shortening and add 10 tablespoons of cold butter cubes. Work in until it resembles crumbs. Add 1 teaspoon of vinegar and 4 tablespoons of water, and toss to combine. The dough should hold together when you gather it up and squeeze it in your hand.


Divide and refrigerate


Divide the dough into two pieces, one slightly bigger than the other (40-60). Shape into rectangles and cover with plastic wrap. Chill in the refrigerator for 30-60 minutes.


Roll pastry


Remove the large piece of dough from the refrigerator and transfer it to a floured work surface. Roll it into a 11x15" rectangle and place in an ungreased 9" x 13" cake pan. Place in the refrigerator to chill.


Heat oven


Preheat the oven to 350 °F.


Fill pastry crust


Spread 1 cup of bread crumbs or crushed cornflakes evenly over the pastry crust and top the crumbs with sliced apples. Sprinkle ⅔ cup of cinnamon-sugar over the apples.


Make pastry lid


Remove the second piece of dough from the refrigerator, and roll it into a 9" x 13" rectangle. Place the lid over the apple filling. Seal the edges of the two crusts and slash the lid several times with a knife to allow steam to escape.


Coat lid sugar


Brush the crust with milk or cream, and sprinkle with sugar.




Bake the pie in the oven for about 60 minutes until the crust is golden brown and the filling is bubbling through the hole in the top.


Leave to cool

Remove the pie from the oven and leave to cool completely.




Combine 1 ½ cups of confectioners' sugar, ⅓ cup of boiled cider, a small pinch of salt and ½ teaspoon of cinnamon and enough milk or cream to make the mixture pourable. Drizzle the glaze over the cooled slab.



Serve the slab cut into even pieces.
