New Jersey winter chocolate cake

This is one of my own. Unfortunately I can't give out the recipe for the cake, but you can use any boxed dark chocolate cake as well.

Ingredients
one 22 inch moist chocolate cake

cream:
2 eggs
2 tbsp corn starch
3 tbsp sugar
6 oz white chocolate chips or chunks
1 cup milk
3 tbsp butter

topping:
1 cup white chocolate chips
0.5 cup cream
0.5 tbsp butter
0.25 cup unsweetened coconut flakes

Preparation
Cool the chocolate cake completely.

For the cream, mix the starch and sugar, then add the eggs and whip until smooth and fluffy.

Bring the milk and butter to a boil and pour in the egg mixture. Stir quickly as it will thicken rapidly. Add in the chocolate chips and cook for 1 minute.

Cover with foil and allow to cool.

Slice the cake using tooth floss or a fancy, expensive Wusthof super slicer knife I wish I had (not really, tooth floss works just fine:-).

Spread the filling onto the bottom half, then replace the top.

For the ganache, bring the cream and butter to a boil and pour onto the chocolate chips. Allow to sit for 2 minutes, then stir until smooth.

When the consistency is just thick enough, that it doesn't run down the cake, pour the ganache on top of the cake. Dust with cocoa powder. You can also decorate it with dark chocolate shavings after it cooled down.
