Method

1. Cream together the sugar and margarine/sunflower spread.

2. Sieve in the gluten free flour and cocoa powder into the sugar and margarine, then beat well until you get a dough type consistency, you may want to use your hands to pull it all together.

3. Grease and line a rectangle baking tray and push the mixture into the tin until all evenly covered, the top doesn't need to be flat, using a palette knife to create some ridges in the gluten free dough is great for some texture and little pockets from the sugar sprinkling to sit in.

4. Bake in an oven preheated to gas mark 6/200c for 25-30 minutes until the top is firm.

5. Remove from the oven and allow to cool slightly, sprinkle over some granulated sugar and then cut into 12 squares while still in the tin, use a fish slice to help remove it from the tin if you need too. Place the pieces on a cooling rack and allow to go fully cold or serve slightly warm with custard.
