To make Jar: Using a funnel, add flour to base of jar, gently tap jar to let flour settle, almost level. Add Cocoa followed by the caster sugar. Add chopped walnuts, and finish off with Milk Choc Bits.
To make Brownies: Preheat oven to 180°C (160°C fan-forced). Grease and line a 22cm square cake tin with baking paper, allowing paper to overhang the edges of the pan.
Melt 290g Dark Melts, 180g butter and ½ cup water in a saucepan over low heat until smooth.
Pour ingredients of jar (sifted flour, cocoa, sugar, milk choc chips and walnuts) in a large mixing bowl. Add chocolate mixture and eggs, then stir well. Pour mixture into prepared tin.
Bake for 45 minutes. Allow to cool in tin for 15 minutes before using the overhanging baking paper to lift out onto a wire cooling rack. Once cool, cut into 20 slices and dust with pure icing sugar.
