  • 2 1/2 cups all purpose flour
  • 8 oz unsalted cold butter, diced
  • 6 tbsp iced water
  • 1 tsp sugar
  • 4-5 large Autumn Glory Apples
  • 1 cup brown sugar
  • 1 tsp cinnamon
  • 1/4 tsp flaky sea salt


  • 1 cup all purpose flour
  • 1/2 cup cold butter, grated
  • 1/4 cup sugar
  • 1/4 cup brown sugar
  • 1/4 cup rolled oats
  • 1/2 tsp cinnamon


  • 1 cup powdered sugar
  • 3 tbsp milk
  • 1 tsp vanilla extract


  • Preheat the oven to 400 degrees F.
  • In a bowl combine the flour and diced butter in a food processor.
  • Add the sugar and iced water and pulse until the dough forms a ball.
  • Cover with plastic wrap and store in the fridge while you prepare the filling.
  • Core and peel the apples and slice into wedges
  • Cut the wedges into small dice and add to a bowl with the brown sugar, cinnamon and salt.
  • Toss well and let rest while you make the slab pie.
  • Take the dough from the fridge and roll it out large enough to fill a 15x10x1 inch baking pan making sure to leave a slight overhang of dough.
  • Place the dough sheet into the pan and press down around the edges making sure to fit it in nicely.
  • Trim any dough around the edges.
  • Take the apple filling and place it into the pie crust spreading the apples out to fit evenly and covering any gaps you can see.
  • In a separate bowl make the topping by combining the flour, grated butter, both sugars, oats and cinnamon.
  • Sprinkle the topping evenly over the apples and bake in the oven for about 45-50 minutes
  • Once the slab pie is baked, make the glaze by whisking the powdered sugar, milk and vanilla together until smooth.
  • Use a spoon to drizzle the glaze over the apple slab pie. Slice into small squares and serve.
