Bonza brownies

1.Turn the oven to 180°C. Grease a 19cm x 29cm slice pan and line the base and sides with baking paper. The paper must come 3cm above all 4 edges of the pan. Chop the butter and put it in a small saucepan on the stove and turn the heat to medium. Put the caster sugar and brown sugar in a large bowl. When the butter is melted, pour it into the bowl and mix together with a whisk.

2.Break 1 egg into a jug then pour it into the bowl with the sugar and whisk to mix together. Repeat this step with the rest of the eggs.

3.Sift both the flours and cocoa into the sugar mixture, then whisk to mix together.

4.Pour the brownie mixture into the prepared pan, using a spatula to scrape out all the mixture. Bake for 15 minutes. Put a sheet of foil over the top of the brownie and continue baking for another 45 minutes. Using oven mitts, take the pan out of the oven and stand it on a wire cake rack. Put a skewer into the centre of the brownie to see if it is cooked. If the mixture sticks to the skewer when it comes out, put the brownie back in the oven for another 5 minutes and test it again. Leave the brownie in the pan on the wire cake rack until it is cold.

5.Using the baking paper, lift the brownie out of the pan and peel away the paper. Cut the brownie into rectangles about 7cm x 9cm. Sift the drinking chocolate over half the brownies and sift the icing sugar over the rest.
