Devils choc slice

Directions

1. 1
   Preheat oven to 350 F (180 C), and grease a 9x13 inch square baking dish.

   Stir together the flour, corn starch, white sugar, brown sugar, cocoa powder, walnuts, baking powder and baking soda in a bowl, sifting with a fork to remove lumps.
3. 3
   Pour in the eggs, apple sauce and margarine, and mix with a large spoon or electric mixer on low until the mixture forms a smooth batter, 3 to 5 minutes.
4. 4
   Scrape the batter into the prepared baking dish.
5. 5
   Place a sheet of aluminium foil on the oven rack to prevent spills as the brownies rise, then fall during baking.
6. 6
   Bake until a toothpick inserted in the centre of the brownies comes out clean, 40 to 45 minutes.
7. 7
   For best results, cover the baking dish with foil for the first 20-25 minutes this technique helps the brownie to rise and keep from drying out too much.
