Sunday Afternoon Chocolate Cake

1 cup SR flour
1/4 cup good quality cocoa
1 cup caster sugar
1/2 cup milk
1 tsp vanilla extract
2 eggs, lightly beaten
125g butter, melted
1 cup icing sugar
1/4 cup good quality cocoa, extra
20g butter, extra
Milk

Pre-heat oven to 180 degrees. Grease and line an 18x18 cm tin with cooking spray and baking parchment.
Melt butter in mixing jug in microwave. Add sugar, combined cocoa and flour, milk, vanilla extract and eggs. Mix as thoroughly as you feel you need to (remember, it is a Sunday afternoon!).
Pour batter into tin and bake in oven for approximately 45 minutes, or until cake is cooked when tested with a metal skewer.
Leave cake to cool.
Wash your mixing jug, or get your other pretty one, and sift icing sugar and cocoa into it. Melt the small amount of butter in a smaller bowl. Add enough milk to make icing sugar and cocoa into a nice icing consistency. Add melted butter as the last step.
Ice cake when cool.
