White chocolate cake with white chocolate frosting

I found this recipes online and decided to give it a try since I have unused cooking white chocolate inside the fridge. Furthermore, it will be different from any of the cakes that I ever baked before. Since I want it to be my birthday cake therefore, it is absolutely necessary to make it extraordinary special. So, here goes;

Ingredients:
21/2 cups of all purpose flour
1 tsp baking soda
1/2 tsp baking powder
1/2 tsp salt
30gm of white chocolate, chopped to pieces
1/2 cup of hot water
1 cup of butter, room temp.
11/2 cup of caster sugar
3 eggs
1 buttermilk ( if you don't have buttermilk you can make yourself, 1cup of milk+3/4 of cream of tartar)

Methods:
1.Preheat the oven to 175C. Sifted the dry ingredient together into a large bowl (flour, baking soda, baking powder & salt).Put aside
2. Melt the white chocolate together with the hot water in a saucepan over a low heat. Stir until smooth and leave to cool.
3. Beat the butter and sugar in another bowl until light & fluffy. Add the egg one by one, beating well with each addition. Stir in the flour/dry mixture alternately with the buttermilk. Mix in melted white chocolate and 11/2 tsp of vanilla essence.
4. Pour the mixture into a cake pans and bake for 30-40min. You can divided the mixture into two if you are using a 9inch round pans.

Frosting ingredient:
30gm white chocolate,chopped
21/2 tbsp all purpose flour
1 cup milk
1 cup butter, room temp.
1 cup white sugar
1 tsp vanilla extract

Method:
1. Combine the flour, white chocolate & milk in a bowl. Cook in a medium heat, stirring constantly until mixture is very thick.
2. Cream butter, sugar & vanilla essence in another bowl. Beat until light and fluffy. Gradually adding the cool chocolate mixture, beat at a high speed until it is the consistency of a whipped cream. Spread the frosting in between the cake, on top & at the side.

So, there it goes. Then you decorate your cake as you wish. This is the end result of my cake, first the side view. All the decoration are edible sugar which you can get from any cake shop.

This is the view from top. The wording are made from chocolate.
