Chocolate custard cake

Boy do I love custard! So when I discovered the custard cake my mind was blown. All made from scratch even though the temptation to grab a tin from the shop was very strong.

Ingredients
4 Eggs -room temperature
1 Tsp Vanilla essence
1 & 1/4 cups of caster sugar
110g Melted butter
1/2cup of plain flour

1 Tbsp icing sugar

Method
1. Preheat the oven to 160 degrees.
2. Grease & line a loaf tin. Well at least thats what I used ;).
3. Seperate the egg yolks from the whites. This is always great fun... not a great one for the nerves.
4. Beat the whites until stiff and put aside.
5. Whisk the egg yolks, vanilla and sugar until creamy.
6. Add melted butter & mix for 30 sec.
7. Add flour and cocoa and mix well.
8. Pour in milk gradually and beat .
9. Add the whites in one third at the time.
10. Pour into the tin and bake for 60 min.
11. Allow to cool and sprinkle with icing sugar.
